Former Nigerian Minister of Petroleum Resources, Diezani Alison-Madueke, has been acquitted of all six bribery charges by a jury at Southwark Crown Court in London, following a lengthy corruption trial.
According to PUNCH Newspapers, the verdict was delivered on Wednesday, June 17, 2026, after more than 46 hours of jury deliberation. The charges included five counts of accepting bribes and one count of conspiracy to commit bribery.
Prosecutors had alleged that Alison-Madueke, who served under former President Goodluck Jonathan from 2010 to 2015, received luxury benefits from oil and gas industry figures in exchange for influence over lucrative Nigerian contracts. She denied all allegations throughout the trial.
The court also cleared oil executive Olatimbo Ayinde and Alison-Madueke’s brother, Doye Agama, who had been co-accused in the case. All defendants were found not guilty after prosecutors failed to convince the jury.
Alison-Madueke, who also briefly served as President of the Organisation of the Petroleum Exporting Countries, maintained that she had no direct control over contract awards and did not receive any bribes.
The verdict marks the conclusion of a case that began more than a decade ago and was closely watched in both Nigeria and the United Kingdom.
British authorities had pursued the investigation as part of wider efforts to tackle international corruption linked to the oil sector.
