Africa Network for Environment and Economic Justice, ANEEJ has expressed deep concern over the acquittal of former Nigerian Minister of Petroleum Resources, Mrs Diezani Alison-Madueke, by a United Kingdom court, describing the verdict as a troubling moment for the global fight against corruption, illicit financial flows IFFs, and impunity, a statement that follows the June 17, 2026, ruling at the Southwark Crown Court in London, where a jury cleared Alison-Madueke of all six bribery charges brought against her by the UK’s National Crime Agency, NCA after a five-month trial and 46 hours of deliberation, while her co-defendants, oil executive, Olatimbo Ayinde and her brother, Doye Agama, were also acquitted, bringing a dramatic end to a saga that began more than a decade ago, a development that prompted ANEEJ to take immediate action today, June 23, 2026, by launching a critical two-day capacity-building workshop in Abuja in collaboration with the Economic and Financial Crimes Commission, EFCC, Nigerian Financial Intelligence Unit, NFIU, a body domiciled within the Central Bank of Nigeria, CBN and Special Control Unit Against Money Laundering, SCUML, an arm of the EFCC to aggressively equip civil society organizations, CSOs with the necessary tools to track, combat, and dismantle these very same illicit financial flows across Nigeria.

Alison-Madueke served as Nigeria’s powerful oil minister from 2010 to 2015 and was the first female president of the Organization of the Petroleum Exporting Countries, OPEC. Her tenure was immediately hit by controversy when former Central Bank of Nigeria, CBN Governor, Sanusi Lamido Sanusi alleged that $20 billion in oil revenue had gone missing under her watch.

In May 2015, just as the administration of President Goodluck Jonathan was handing over power to Muhammadu Buhari, Alison-Madueke left Nigeria for London. By October 2015, the UK’s NCA arrested her on suspicion of bribery and money laundering, seizing her passport and sparking a 13-year international investigation.

For years, Alison-Madueke’s legal team fiercely resisted attempts by Nigeria’s Economic and Financial Crimes Commission, EFCC to extradite her back to Abuja to face separate corruption charges. Her prolonged stay in the UK was repeatedly defended on critical medical grounds.

Her lawyers disclosed that she was diagnosed with “triple-negative cancer,” describing it as the most aggressive form of breast cancer. Over the decade, her defence stated that she underwent multiple major surgeries and extensive chemotherapy treatments in London hospitals, leaving her at one point in a coma due to medical complications.

These health battles, combined with the extreme complexity of cross-border financial tracking, left her on continuous UK bail for eight years before she was formally charged in 2023.

Despite prosecutors presenting evidence that oil contractors funded a “life of luxury” for her in London—including spending £2 million at Harrods, securing private jet flights, and occupying high-end properties—the case ultimately collapsed because the prosecution failed to meet the strict criminal standard of proof.

The Southwark Crown Court acquitted Alison-Madueke based on two central pillars: Failure to Prove Direct Bribery; the jury found that the prosecution’s evidence was largely circumstantial. Alison-Madueke successfully argued that she maintained strict due process, had no direct authority over contract awards, and that any luxury spending cited by the prosecution was either personally reimbursed or fell under official state business expenses.

The “Broken” System and Gross Delays: Her defence team successfully argued that the extraordinary 13-year delay by British authorities ruined the fairness of the trial. They asserted that the passage of time, coupled with a “broken criminal justice system,” made it impossible for the defendants to access vital exculpatory documents and evidence remaining in Nigeria to prove their innocence.

While acknowledging the independence of the British judicial system, the ANEEJ leadership warned that the collapse of such a prominent international prosecution sends a dangerous signal to corrupt actors across the continent.

“While ANEEJ respects the independence of the British judicial system and the verdict reached by the court, this outcome represents a major setback in efforts to hold politically exposed persons accountable and combat grand corruption. It risks emboldening kleptocratic governments, corrupt public officials and their enablers across Nigeria and Africa who continue to loot public resources with impunity,” said Reverend David Ugolor, Executive Director of ANEEJ.

The organisation noted that the verdict deals a heavy blow to the UK’s historical reputation as a leader in international asset recovery, transparency, and beneficial ownership reforms. ANEEJ expressed worry over a growing retreat by major Western democracies from robust action against grand corruption.

Ugolor warned that if the UK and the US take a back seat, prospects for ending impunity in Africa will become increasingly uncertain. “The collapse of one of the most prominent corruption prosecutions involving a former African public official may weaken confidence in these commitments and undermine broader international efforts to tackle illicit financial flows.

“At a time when corruption continues to fuel poverty, inequality, insecurity and democratic backsliding across Africa, diminished international resolve risks strengthening those who profit from state capture and weak governance,” Reverend Ugolor added.

A key point of concern for the International human and environmental rights watchdog, ANEEJ is the sharp contrast between the London acquittal and established legal realities in Nigeria. Over the years, Nigerian courts have successfully ordered the forfeiture of billions of naira worth of properties, cash, and luxury items linked directly to the former Petroleum Minister.

ANEEJ emphasized that these domestic recoveries, secured through lawful judicial processes, underscore the massive scale of illicit wealth accumulated. The UK acquittal, therefore, raises difficult questions about the effectiveness of cross-border enforcement and the capacity of international institutions to bring complex grand corruption cases to a successful conclusion.

“These recoveries, secured through established legal channels, underscore the scale of illicit wealth allegedly accumulated and the importance of sustained international cooperation in tracing, freezing, confiscating and repatriating stolen assets. The acquittal therefore raises difficult questions about the effectiveness of cross-border anti-corruption enforcement and the ability of national and international institutions to bring complex grand corruption cases to a successful conclusion,” Ugolor said.

ANEEJ warned that the judgment could demoralise citizens, anti-corruption agencies, whistleblowers, and investigative journalists who risk their lives to demand transparency. However, the organisation stressed that the verdict must serve as a critical wake-up call rather than a deterrent.

ANEEJ called on African governments and international partners to redouble their efforts by strengthening local institutions, improving cross-border judicial cooperation, protecting whistleblowers, and closing the financial loopholes that facilitate illicit flows. “The fight against corruption is ultimately about justice for citizens. It is about ensuring that public resources are used to improve lives rather than enrich a privileged few.

“The struggle against corruption and illicit financial flows remains central to achieving democracy, sustainable development and social justice across Africa,” Ugolor said, reaffirming ANEEJ’s commitment to working with Nigerian and international institutions to ensure stolen public assets are recovered and used to improve public lives.

In direct response to these ongoing transparency challenges and the staggering scale of national losses, ANEEJ today, June 23, 2026, commenced a two-day capacity-building workshop in Abuja focused on addressing Illicit Financial Flows, IFFs in Nigeria.

The training brings together key Civil Society Organizations, CSOs alongside distinguished stakeholders, including SecFin Africa representative, Professor Abdullahi Shehu, and the Nigeria Financial Intelligence Unit, NFIU—represented by Chief Governance, Risk and Compliance Officer, Mr Ibrahim Muhammed on behalf of Hafsat Abubakar Bakari.  Representatives from the Special Control Unit Against Money Laundering, SCUML and the Economic and Financial Crimes Commission, EFCC are also participating.

In his welcome remarks, ANEEJ’s Deputy Executive Director, Atakpu Leo, emphasized that the workshop is part of the project, “Strengthening CSOs and Media Capacity to Contribute to the Fight Against Illicit Financial Flows in Nigeria.” He highlighted the critical role of CSOs in advancing public accountability, citizen mobilisation, budget monitoring, procurement tracking, tax justice advocacy, anti-corruption campaigns, and policy engagement.

According to Leo, the workshop aims to deepen participants’ understanding of the nature, drivers, trends, and developmental impacts of IFFs, while strengthening their knowledge of relevant legal, policy, and institutional frameworks. It also equips CSOs with practical tools for evidence-based advocacy, procurement monitoring, Freedom of Information, FOI utilization, data access, coalition building, and strategic institutional engagement.

Delivering a goodwill message, Professor Abdullahi Shehu noted Nigeria’s strategic importance within Africa and commended ANEEJ for its outstanding research on IFFs. He encouraged participants to actively engage in governance processes, hold elected officials accountable, and participate in democratic processes, including voter registration.

Representing NFIU, Mr Ibrahim Muhammed reiterated the importance of understanding IFFs beyond financial crimes, stressing Nigeria’s significant role in combating illicit outflows. He underscored the need for collective action across sectors, noting that illicit flows can occur through multiple channels, including financial institutions and non-profit organizations.

Similarly, Mr Pascal Joseph Samu, who represented SCUML, an arm of the EFCC, highlighted the severe developmental impact of IFFs, revealing that Nigeria has lost over $77.7 billion in the last decade, with an estimated $18 billion lost annually.

He emphasized SCUML’s commitment to implementing Beneficial Ownership Transparency as a key measure to curb IFFs and reaffirmed institutional support for the workshop’s outcomes.

The workshop continues with strong collaboration among stakeholders, reinforcing a collective commitment to combating illicit financial flows and strengthening transparency, accountability, and sustainable development across Nigeria.
