Abstract

The study examines the influence of whistle-blower engagement and integrity management in Nigeria’s public sector particularly in the Federal Ministries, Departments and Agencies (FMDAs) and proposes a stakeholder-led process of whistleblower mobilization as a means to address financial fraud. The study gathered data from 285 Heads of Department and accountants in FMDAs within Ondo State, utilizing a survey research design. A purposive sample was taken of those who had useful professional and administrative knowledge. A regression analysis was performed to determine the impact of whistle-blowing mechanisms, expert accountants, and internal control systems on  integrity management in Nigeria’s public sector. The results show that whistle-blowing mechanisms and internal controls have a positive significant influence on integrity management in Nigeria’s public sector with fight against financial fraud which play an important role in fraud reduction. The findings further revealed that the role of expert accountants was but not significant at 5% level of significant on the achievement of good organizational transparency and accountability. The study ultimately concluded that fraud cannot effectively be inhibited unless whistle-blowing protections, enhanced internal controls, and professionalism are all adopted in unison. The study recommended that government should establish a protection safety for whistleblowers; improvement of internal controls, and situating competent accountants within a larger context of compliance and governance initiatives because all these mechanisms add to the trustworthiness and responsiveness of anti-fraud mechanisms in public sector institutions in Nigeria. The implication of the findings implies that strengthening whistle-blowing mechanisms and internal controls is essential for enhancing integrity management and combating financial fraud in Nigeria’s public sector, thereby promoting greater transparency and accountability. The study call on the government to prioritize institutional reforms and encourage the general public’s confidence in public sector governance.

Keywords: Stakeholder approach, financial fraud, expert accountants, whistle-blowing, internal control.

1.0 Introduction

In an era where transparency is the bedrock of sustainable governance, whistle-blower engagement stands as a courageous beacon against corruption. An Auditor‑General’s report (covering 2020-2021) found over ₦197.7 billion paid irregularly by 32 MDAs in breach of procurement regulations. Highlights include ₦7.4 billion awarded without tender procedures; ₦167.6 billion paid for contracts that were never executed or were only partially done; and additional violations include improper contract awards and missing approvals. These cases illustrate large-scale financial misconduct within Nigerian MDAs, highlighting the urgent need for accountability, better internal governance, and stricter enforcement of financial regulations (Okafor et al., 2025; Bussey et al., 2024). Financial fraud is committed either on operational or managerial grounds, and the masterminds express themselves according to income levels (Chingwere et al., 2025). Ogunfowora et al. (2022) state that cases of fraudulent behaviors have been rather common lately mainly in emerging economies, financial institutions, investors and the people have lost through scams. According to the idea developed by Apalowowa et al. (2023a), fraud involves a deliberate and concealed undervaluation of an asset to gain benefit out of the same in individual or collective interests. The idea of legality on whistleblowing itself originated in the Western world and led to the U. S Sarbanes Oxley Act of 2002 requires corporations to offer whistle blower hotline access to employees in an anonymous and confidential manner. Bussey et al. (2024) posited that “internal control is conducted in an orderly manner by the management and employees of the organization to ensure that sufficient material is reported accurately in terms of financial reporting, laws, and regulations are followed among other factors based on the performance and efficiency of the operation”. Corporate governance is structures, process and rules which have been gained in the process of making an effort to ensure that a firm is managed in a way which fulfills towards achievement of the goals and interest of stakeholders (Awale et al., 2025).

Apalowowa et al. (2023b) argue that accountants are among the main in-gredi-ents that retain the credibility of auditors in the auditing area which ensures the generation of confidence of the general public in relation to the reliability and integrity of the financial records that are presented by the clients. Accountants need exposure to experience in the prevention of fraud and traditional auditing is needed to ensure integrity of the auditors. As shown in the case described several cases fail to follow their set pattern; this is attributed to the following reasons (Bussey et al., 2024). There is also a higher number of financial frauds; the accountants are also to be involved in the process of investigations and sentencing started against the illegal activities; their role in such a case is highly important (Okafor et al., 2024). However, the greatest variation of N2.12 billion was realized within the Rural Electrification Agency in Abuja. Enron, Arthur Andersen, and WorldCom are the most widespread fraud scandals that jolted the business community, and due to massive theft, there has been a worrisome erosion of the public confidence in the finances of Nigerian federal MDAs and lack of reliance on the integrity of the other departments by the heads of the departments and accountants. Major irregularities in budgets have been revealed in the audits of Nigeria MDA recently because expenses incurred on contracts through the unauthorised payment that was done by a breach of the Financial Regulation Paragraph 2921(i) 2009 amounted to N7.39 billion. Hence, the study examines the influence of whistle-blower engagement on integrity management in Nigeria’s public sector particularly in the Federal Ministries, Departments and Agencies (FMDAs) and proposes a stakeholder-led process of whistleblower mobilization as a means to address financial fraud and closes the gap in the literature of existing empirical studies.

2.0 LITERATURE AND THEORETICAL UNDERPINNING

2.1 Conceptual Review

2.1.1 Financial Fraud

Financial fraud refers to intentional act of deception through financial activities in pursuit of personal benefit or loss on a third party. Yahaya et al. (2024) assume that financial fraud is an act of misstatement, concealment of material information, manipulation of financial data to deceive investors, shareholders, banking institutions and regulating authorities. Financial fraud can harm financial systems seriously, including the trust in stakeholders. Financial fraud negatively affects corporate governance, falsifies financial reporting, and may trigger severe economic, reputational, and legal expenses among the offenders (Apalowowa, 2025). Financial fraud is a broad category of criminal activities that consists of embezzlement, insider trading, accounts falsification, misappropriation of assets, and fraudulent financial reporting by both perpetrators of fraud that encompass company managers and staff, and external parties, such as auditors and investors (Apalowowa et al., 2025). With respect to financial fraud organizations and regulatory bodies have formulated more rigid compliance regimes like forensic accounting tools and techniques, as well as elevated systems of auditing with is ever-changing and dynamic on how financial fraud should be dealt with in this ever-changing world thus requires a constant vigilance and an active stewardship to bring forth organizational integrity and sustain financial transparency (Awale, et al., 2025; Bussey et al., 2024).

2.1.2 Expert Accountants

Okeke et al. (2024), expert accountant plays major role in the trials that are conducted in courts in case of financial crimes, litigations and compliance to regulations because they provide proofs and clarify in the war against fraud cases. Expert accountants perform tests of anomaly and irregularity in the financial statements that might cause suspicion of frauds with the help of data analysis, making investigation on verification and audit of financial reports, and interviewing as a means of seeking some traits of fraud (Sibe & Kaunert, 2024).

 

2.1.3 Whistle-Blowers

A whistle blower is a person who exposes wrong-doings, financial crimes, environmental violations, workplace bullying or safety breaches in a broad range of an organization to state agencies or any other associations (Ugwu, 2011). Whistleblowers include either the staff, subcontractors and non-personnel who possess personal knowledge of the malpractice (Sule, 2025). Whistle blower refer to moral responsibility and ethical appeal provokes whistleblowing because a conscience bear unlawful and harmful actions which one is engaged in and which lead to the emergence of suspicious questions, remedial actions, and changes to prevent further damage and the establishment of law (Yahaya et al., 2024).

2.1.4 Mechanisms of Internal Controls

The proposed internal control of Uchenna et al. (2025) is a formal procedure implemented by the management and staff of the company to present a reasonable degree of certainty regarding the achievement of objectives based on efficiency and effectiveness of operation, good financial reporting, and the compliance with the required laws and regulations. Sibe and Kaunert (2024) outline that the primary objectives of internal control include the protection of assets, the completeness, and accuracy of financial data and detection of errors, fraud, and other irregularities. A good internal control system is formulated with firm operation and other activities and practices. Probably, nothing is as crucial an instrument a firm could have at its disposal as far as guaranteeing that a firm is operating in line with its legalities and intentions (Apalowowa et al., 2023b).

2.2 Theoretical Review

2.2.1 Moral Disengagement Theory

In 1986, Albert Bandura developed the Moral Disengagement Theory. This theory assumed that people were able to behave in a way that defined as unethical and immoral denying their moral principles and even call a certain harmful activity excusable. The theory assumes that the moral discomfort caused by the antisocial action mitigated with the aid of the displacement of guilt, diffusion of responsibility, dehumanization and endorse the cognition justification of the wrongful conduct (Chingwere et al., 2025; Ogunfowora et al., 2022). Moral disengagement is propagated by group processes and social contexts too; their efficiency and execution makes people prone to justifications of anti-constructive actions (Luo & Bussey., 2023). The critics believe that Moral Disengagement Theory difficult to apply the theory of Bandura to large cultural domains because the theory fails to offer an explanation on the plasticity of moral structures within civilisations and societies ((Bussey et al., 2024; Okeke et al., 2024; Okafor et al., 2024). The theory has had wider application in the explanation of behaviour as diverse as the violent behaviour to corporate deviance in different settings.

2.3 Empirical Review

Ali-Momoh et al. (2025) examine the strategic forensic role of forensic accounting in combating environmental fraud and enhancing the integrity of corporate financial reporting. This research, performed via a systematic survey of 30 intentionally chosen professional accountants at Afe Babalola University Ado Ekiti, Nigeria, produced noteworthy results. Regression analysis indicates that fraud detection exerts a strong, positive, and robust influence on the quality of financial reporting (β = 0.887, p < 0.001), hence confirming its role in improving transparency and trust. However, fraud prevention techniques exhibit a minimal and insignificant impact (β = 0.019, p = 0.891), indicating the need to modify the strategic approach.

Apalowowa (2025) examined the correlation between white-collar fraud and whistleblower investigations. The research employs a survey methodology, collecting data directly from participants; the analysed sample comprises 83 forensic auditors from southwestern Nigeria. The Census Sampling Technique was employed for the selection of the entire population to be studied. His findings indicate that although the effectiveness of forensic audits is positively associated with whistleblowing, internal controls, and corporate governance, none of these characteristics yielded statistically significant outcomes at conventional criteria (p > 0.05). The z-statistic values of 1.2521 for corporate governance, 1.1783 for internal controls, and 1.1647 for whistle-blowing suggest that the observed correlations are due to random variation rather than authentic causal relationships.

Apalowowa et al. (2025) examined the prophylactic function of the forensic auditor following the implementation of forensic auditing. They employed purposive sample techniques in their research utilising a survey approach grounded in a questionnaire. The target audience comprised 210 staff members from three state-owned colleges in Ondo State, specifically those employed in the Departments of Audit (source: Attendance Register, 2025). The study was performed with 120 senior personnel possessing ICAN and ANAN qualifications. The findings of their research demonstrate that responsive planning approaches lack statistical significance, but effective internal control and robust managerial supervision are statistically significant, with p-values of 0.0000 and 0.00105, respectively.

The quantitative findings were based on the research conducted by Abraham et al. (2025), which sought to evaluate the impact of perceived work alienation on the intention to whistleblow, with religious-political orientation serving as a mediator and social value orientation as a moderator. The study involved 263 Indonesian individuals, comprising 131 men and 132 women, and was conducted as correlational predictive research featuring mediation and moderation analysis. The standard deviation was 5.47 years, while the mean age of the participants was 25.91 years. The data suggest that the adverse impact of job alienation diminishes the likelihood of whistleblowing intentions. The current study found that prosocial social value orientation mitigates the inverse association between job alienation and the desire to whistleblow, while religious-political orientation does not significantly mitigate this inverse relationship as hypothesised.
Atmadja et al. (2024) examined the influence of internal control systems, compliance with human resource regulations, and competency on accounting fraud within the regional financial administration of Gianyar Regency, Indonesia. The quantitative technique including informational analytical procedure offered in the present research examined a survey questionnaire that was filled by the employees of the local work unit in Gianyar Regency by employing the multiple regressions. This study employs Non-Likelihood testing within the Purposive Sampling technique, revealing that internal control systems, negative regulatory compliance, and human resource capabilities all significantly influence accounting fraud in the Gianyar Regency Provincial Work Unit. Romero-Carazas (2024) discusses the accountant's role in adopting artificial intelligence, utilising numerous sources and bibliometric analysis from Scopus. The example documents were identified using Boolean operators and English terms such as forensic, auditing, artificial, and intelligence. Subsequently, VOS Viewer and Excel were employed for analysis. This research proposes three aspects concerning accountants' interest in AI development: the comprehensiveness of the topics addressed, the gravity of the offences committed, and the source data involved. The FMDAs in Ondo State provide training for their Department Heads and Accountants on new technologies, artificial intelligence courses, and collaboration with diverse specialists to maintain the highest levels of honesty and quality in their work. Odeyemi et al. (2024) delineate the function of accountants in contemporary society and present concepts about the implementation of digital strategies and new technology. It is also a strong hint for forensic accountants to update their technologies to address and combat contemporary fiscal crimes. The essence of the investigated topics culminates in the assessment of employing blockchain, machine learning, and artificial intelligence-driven data analytics in the procedural functions of accountants. It indicates that economic crimes are continuously evolving; therefore, forensic accountants must adapt to new methods and innovations for tracking fraudsters who utilise internet media to commit such offences.
In their 2024 study, Olutimehin et al. examined the compliance practices of corporate governance among Nigerian companies and identified deficiencies in executive remuneration, board independence, and risk management, while noting strengths in compliance policies, financial reporting, and board effectiveness. It analyses the influence of social, cultural, and economic variables on governance dynamics and advocates for firm and context-specific strategies that address local business conditions in Nigeria. It asserts the necessity of investing in stakeholder engagement processes that encompass communication, collaboration, and the development of shared value, which will effectively connect business objectives with the expectations of the populace. Consequently, technology-enabled solutions can be used to facilitate feedback loops and real-time communication among stakeholders, while online platforms will be utilised to provide informed and participative comments.

Chidi et al. (2024) aim to determine the impact of internal control on supermarket efficiency through measures such as division of labour, time and leave reporting, firewall protection, regular updates of job descriptions, documentation and record-keeping, and physical barriers to unauthorised access. The research employed a quantitative methodology utilising questionnaires as the research instrument. The study's population comprised all 192 employees of the main retail malls in Awka, Anambra State. The sample size was determined using a formula established by Krejcie and Morgan (1970). Multi-linear regression is utilised to determine the relationship between the dependent variable and the independent factors. Their empirical findings demonstrated that the components of the internal control system exerted varying degrees of influence on operational effectiveness.

Okwuokei (2024) discusses the role of whistleblowers in Nigeria combating corruption and advocates for the establishment of legal protections and incentive mechanisms. The background information in whistleblowing is twofold: it can be utilised to disclose irregularities and to assess the risks faced by the whistleblower. Whistleblowers are vulnerable due to the absence of protective legislation; they frequently face harassment, intimidation, and even termination from their employment. The essay highlights the necessity of enacting legislation such as the Whistleblower Protection Act in the United States to provide adequate protection.

Yahaya et al. (2024) evaluate the efficacy of whistleblowing policies in mitigating the severity of corruption in Niger State. The research employed survey methodology, utilising questionnaires as the data collection tool, and incorporated a mixed-methods approach, integrating both qualitative and quantitative data formats. The respondents selected for this study include workers from the following stakeholder groups: government officials, whistleblowers, and civil society members in the State of Niger. The uncomplicated random sample method was employed to obtain over 300 participants for the survey. The paper utilises a straightforward percentage, means, rankings, and frequency count in a multiple regression analysis. The whistleblower strategy has proven helpful in reducing corruption in Niger State by promoting accountability and transparency within regional institutions.
Apalowowa et al. (2023) examined how auditor activities may affect fraud investigation, prevention, and detection inside the State Pension Board in Nigeria. Employed primary data methodologies to perform a survey-based study. There were 186 employees aged from the State Pension Board in the three selected states. The study employed stratified and census sampling methods, with analysis conducted by Ordinary Least Squares Regression. Accountants are essential in the investigation, prevention, and detection of fraud. The findings established that internal audit and transparency and accountability rules significantly influenced the prevention and detection of fraudulent incidents.

Wokeh (2020) examined the impact of internal control on the financial performance of Deposit Money Banks in Nigeria. The triangulated methodology is employed for research purposes. The sample population comprises two hundred and twenty (220) individuals randomly selected from the thirteen (13) designated deposit money institutions. The hypothesis was tested using multiple regression analysis facilitated by the statistical software Stata12. The risk assessment exerted a positive albeit negligible impact on the net profit margin of the listed deposit money banks in Nigeria, whilst the control environment had a negative and insignificant effect.

2.4 Knowledge Gap

Enron, Arthur Anderson, and WorldCom (Oluzimehin et al. 2024), Yahaya et al. 2024, Odeyemi et al. 2024; and Apalowowa (2024) discussed the variation in literature on the role of accountants as whistleblowers since investigation approaches to detecting anomalies in Nigerian Federal MDAs help an individual comprehend some of the most notable issues missing in past research studies and hence the current study furthered. The prior research is primarily independent in its focus on white-collar crime, whistleblowing, and forensic auditing. At the same time, this research incorporates accountants' role and systems of whistleblowing as complementary approaches within the Nigerian federal MDAs for fiscal anomaly detection and avoidance that previous research has not addressed. By filling these gaps, this study adds to the body of knowledge on how stakeholder orientation to whistle-blower participation in fraud investigation enhances the financial integrity of the Head of Departments and Accountants working in federal MDAs in Ondo State, Nigeria.

3.0 Methodology

The study adopted a census sampling technique to select all 285 accountants and heads of departments working in federal Ministries, Departments, and Agencies (MDAs) in Ondo State, Nigeria. This approach was deemed appropriate due to the manageable size of the population and the need to capture comprehensive insights from every relevant respondent within the targeted institutions. Ethical considerations were duly observed in the course of the study. Participants were informed of the purpose of the research and assured of the confidentiality and anonymity of their responses. Their participation was entirely voluntary, with informed consent obtained before administering the research instrument. The primary instrument for data collection was a structured questionnaire designed to elicit accurate and relevant responses. It was rated on a four-point Likert scale (Strongly Agree = 4, Agree = 3, Disagree = 2, and Strongly Disagree = 1), which helped quantify attitudes, opinions, and perceptions of the respondents in a measurable form. To ensure the reliability of the instrument, a pilot test was conducted and the resulting data subjected to internal consistency analysis using Cronbach's Alpha, which confirmed that the questionnaire items were reliable for data collection. Data gathered from the Likert scale responses were analyzed using descriptive and inferential statistical tools and regression analysis was utilised to determine the relationships between whistle-blower engagement and integrity management in Nigeria’s public sector.

Data Analysis

Table 1 presents the result of multiple regression analysis of whistle-blower stakeholder strategies and integrity management in Nigeria’s public sector. The results indicated existence of a statistically significant relationship as supported by the F-statistic value of 15.325 and the Prob(F-statistic) value of 0.0000, which shows that stakeholder approach to whistle-blower engagement and integrity management in Nigeria’s public sector was significant at the 1% level. An R-squared of 0.5614 indicates that the study accounts for about 56.14% of the variation in combating financial fraud. Adjusted R-squared of 0.5410 also supports the strength of the findings, considering the number of predictors entered. The coefficient (0.4092, p = 0.0046) of whistle-blowing indicates that effective whistle-blower mechanisms play a crucial role in assisting in combating financial fraud. Financial fraud (0.6321, p = 0.0032) significantly interacts with other predictors, having a strong positive correlation with the success of stakeholder action. The expert accountant with coefficient (0.5510, p = 0.0621) is not statistically significant at the 5% level. Internal Control Mechanisms (0.5432, p = 0.0010) are very significant at the 1% level. Robust internal checks and balances are essential components of fraud prevention solutions for stakeholders. The Durbin-Watson statistic of 1.3821 is somewhat lower than the ideal value of 2 and can indicate a positive outcome. The insignificance for expert accountants was ascribed to various crucial issues. Initially, the implementation of specialised accountants within MDAs restricted in extent, inadequately incorporated into whistle-blowing mechanisms and hindered by institutional obstacles such as bureaucratic delays, corruption, and insufficient autonomy. Moreover, professional accountants encounter ethical dilemmas and systemic pressures that undermine their ability to behave independently commence fraud investigation. The function of specialist accountants eclipsed by more immediate, enforceable measures such as whistleblower protections and internal controls, which seem to be more actively employed and institutionally reinforced inside the public sector framework.
The practical implication of the findings are substantial to policymakers and anti-fraud strategists that dependence solely on professional skills, absent structural empowerment and autonomy are factors. Consequently, greater emphasis should be placed on integrating accountants into a framework of responsibility that enhances their efficacy, granting legal protection, improving access to fraud-reporting mechanisms, and preserving ethical autonomy necessity of enhancing whistle-blower frameworks and internal controls, which have demonstrated greater statistical significance in fostering honesty.

4.2 Discussion of Findings

Regression results indicate that stakeholder policies concerning the use of whistleblowers have considerable impacts on fraudulent financial activity prevention measures. The study is statistically significant to establish that stakeholders the use of whistle-blowing tools, using specialist accountants, and making internal controls an important element used in fighting financial malpractice. Whistle-blowing systems, specifically proven effective in supporting the contention that well-protected and clearly defined disclosure mechanisms increase fraud detection and discourage fraudulent activity. Therefore, organisational and regulatory authorities need to prioritize the establishment of open and encouraging whistle-blowing systems as central components of anti-fraud initiatives. The results show a clear relationship between fraud case numbers and responses from the stakeholders. Their presence also positively influences the outcome, although the influence is not statistically significant at a significant level. This means that professional accountants are useful has their impact could be more beneficial to institutions andhelp with governance. Internal controls also make stronger and shown that they are a crucial factor in avoiding financial fraud. This shows that robust internal controls, such as checks and balances, audit trails, and reviews for compliance, are extremely critical to making organisations transparent and accountable. The findings of this study correspond with the findings in the study of Olutimehin et al. (2024) in their study, they examined corporate governance practice among Nigerian companies and found evidence of strengths on compliance policies' sides, financial reporting's sides, and board's sides, but not on executive remuneration's sides, board independence's sides, and risk management's sides. However, this study disagreed with the findings in the study of Abraham et al. (2025) that aimed to estimate the influence of perceived work alienation on the intention to blow the whistle, where the religious-political orientation was used as a mediator and a social value orientation as a moderator. Their research was discovered in the current research which indicated that having prosocial social value orientation safeguards the reverse relationship between job alienation and whistleblowing intention and that of religious-political orientation having insignificant buffer of the reverse relationship as the current research said.

Implication of Findings

The study is the importance of establishing a comprehensive fraud management system which spans policy, people, and structural controls to encouraged and institutionalise whistle-blower protection, make a commitment to continuous internal control improvement, and invest in professional accountants, who are situated in compliance and governance contexts to enhance their contributions to anti-fraud endeavour and financial accountability.

Conclusion

Based on the study's findings, the study concluded that tools such as whistle-blowing, internal controls, and expert accountants are all important in helping to prevent and detect organizational financial fraud; Corruption persecution policies are of great system in uncovering fraud as well as acting as a disincentive for offenders when adequately protected and incentivized; and good accountants are generally a positive influence in anti-fraud initiatives, without proper supporting structure and institution role reinforcing the argument for a comprehensive fraud management system.

Recommendations

The study recommended that; organizations should strengthen and entrench the process for whistle-blowing through the enactment of policies that protect confidentiality, safety and legal support to the whistle-blower; Strengthening internal controls to close exploitable gaps by fraudsters should be part of an on-going process of continuous improvement of the fraud risk management system, rather than something done once a fraud incident occurs; and stakeholders should seek to hire and train accountants with existing expertise, and then situate these accountants within larger structures of compliance and governance to be most effective.
