In its latest 9th edition of compendium, the Human and Environmental Development Agenda (HEDA) Resource Centre has revealed the vast scale of corruption in Nigeria, documenting 100 high-profile cases involving public officials and private individuals. According to the compendium, allegedly stolen amounts are reported in multiple currencies: N1.387 trillion, $53.84 billion, and £1 million. The report, unveiled in December, commemorating the international anti-corruption day by the civil society organisation in Lagos, referenced pending court cases involving former governors, ministers, senators, and other public officials accused of fraud, money laundering, embezzlement, and abuse of office. Notable high-profile cases in the compendium include one involving former Anambra State Governor Willie Obiano, who is accused of money laundering involving N4 billion in public fund. Former Accountant-General of the Federation Ahmed Idris is facing trial over alleged N109 billion fraud. In contrast, former Kogi State Governor Yahaya Bello faces N110 billion in fraud charges and property forfeiture worth N80.2 billion. Former Minister of Power and Steel Olu Agunloye is also undergoing prosecution for a $6 billion scheme tied to the Mambilla Hydroelectric Plant, while former Petroleum Minister Diezani Alison-Madueke faces allegations of $20 billion in fraud and property forfeiture. Other notable cases include Ali Bello and Daudu Sulaiman’s N10 billion fraud case and Fatuyi Yemi Phillips’ N43.5 billion misappropriation allegations. Prominent former governors also appear in the compendium. Former Abia State Governor Orji Uzor Kalu, who is a serving senator, also faces N7.6 billion money laundering allegations. Former Taraba Darius Ishaku and former Abia State State Governor Theodore Orji are linked to N27 billion and N60.85 billion fraud cases, respectively, while former Benue State Governor Gabriel Suswam faces allegations involving N3.1 billion money laundering. The compendium also listed cases involving corporate and agency officials. Former AMCON Managing Director Ahmed Kuru faces N33.8 billion in money laundering charges, while former Central Bank Governor Godwin Emefiele is also facing corruption charges in different courts in Lagos and Abuja. According to the report, fraud, money laundering, and embezzlement dominate high-profile financial misconduct, often accompanied by abuse of office. It added that the Economic and Financial Crimes Commission (EFCC) is prosecuting 76 per cent of these cases, while the Independent Corrupt Practices Commission (ICPC) handles 16 per cent. Other agencies involved include the Code of Conduct Tribunal (CCT) and the National Drug Law Enforcement Agency (NDLEA). Analysis shows former governors account for 16 per cent of defendants, former ministers and advisers 7 per cent, senators 1 per cent, and other public officials 76 per cent. Most cases (58 per cent) are ongoing; 11 per cent have resulted in sentencing, and 9 per cent involve property seizures. Fraud accounts for 54 per cent of charges, money laundering 20 per cent, and misappropriation or mismanagement 8 per cent. The report said corruption increases the cost of doing business, discourages investment, and undermines economic and political decisions, contributing to underdevelopment, insurgency, forced migration, and widespread poverty. HEDA researchers compiled the report by reviewing all available sources on 100 high-profile cases, the data with current information, and analysing it using IBM SPSS Version 23 to produce tables, histograms, and visualisations.
