A London jury has delivered an Alison-Madueke acquittal, clearing former Nigerian Minister of Petroleum Resources, Diezani Alison-Madueke, of six bribery-related charges. The verdict was returned on Wednesday following a lengthy trial at Southwark Crown Court in the United Kingdom. The decision concludes a high-profile case that stemmed from corruption investigations initiated more than a decade ago.
Diezani Alison-Madueke served as Nigeria’s Minister of Petroleum Resources between 2010 and 2015 during the administration of former President Goodluck Jonathan. She also briefly served as president of the Organization of the Petroleum Exporting Countries (OPEC), placing her among the most prominent figures in Nigeria’s energy sector during that period.
British authorities began investigating allegations involving the former minister more than ten years ago. The case drew significant attention because of Alison-Madueke’s former role in overseeing one of Nigeria’s most important economic sectors.
Prosecutors alleged that Alison-Madueke, 65, received what they described as “a life of luxury” in London from oil and gas industry figures seeking access to lucrative contracts in Nigeria. She was charged with five counts of accepting bribes and one count of conspiracy to commit bribery.
Throughout the proceedings, Alison-Madueke denied all allegations. She maintained that she never accepted bribes and argued that she did not exercise direct influence over the awarding of government contracts.
Following more than 46 hours of jury deliberations, the court returned not guilty verdicts on all six charges. The Alison-Madueke acquittal marked the end of the criminal proceedings against the former minister in the United Kingdom.
The case also involved oil industry executive Olatimbo Ayinde, 54, who faced one count of bribery relating to Alison-Madueke and a separate charge of bribery of a foreign public official. Alison-Madueke’s brother, Doye Agama, 69, was charged with conspiracy to commit bribery in connection with payments allegedly made to Agama’s church.
Both Ayinde and Agama denied the allegations against them. The jury acquitted both men of all charges.
The Alison-Madueke acquittal represents a significant outcome in one of the most closely watched corruption cases involving a former Nigerian public official in a foreign jurisdiction. The verdict is also a setback for British authorities, whose investigation into the allegations extended over a decade.
The case attracted attention in Nigeria and internationally because of its connection to governance, public accountability, and the management of resources within the oil and gas sector.
With the jury’s decision, criminal proceedings against Alison-Madueke, Ayinde, and Agama in the case have concluded. The verdict brings to a close a long-running legal process that examined allegations of bribery linked to Nigeria’s petroleum sector and resulted in acquittals for all three defendants.
