Main Story
Nigeria’s former Minister of Petroleum Resources, Diezani Alison-Madueke, has been cleared of all bribery charges brought against her by British prosecutors after a jury returned unanimous not-guilty verdicts at Southwark Crown Court.
Alison-Madueke, who served as petroleum minister between 2010 and 2015 under former President Goodluck Jonathan, was acquitted on five counts of accepting bribes and one count of conspiracy to commit bribery.
The 65-year-old former minister had consistently denied the allegations.
British prosecutors alleged that she received luxury benefits and enjoyed what they described as a lavish lifestyle funded by oil and gas industry figures seeking favourable treatment and lucrative contracts in Nigeria’s petroleum sector. According to the prosecution, the benefits were allegedly provided in exchange for influence over government decisions and contract awards. However, Alison-Madueke maintained throughout the proceedings that she neither accepted bribes nor exercised direct control over the award of government contracts.
Following more than 46 hours of deliberations, the jury found her not guilty on all six counts, bringing the trial to a close. The verdict represents a significant setback for British authorities, whose investigation into corruption allegations involving the former minister began more than a decade ago. Alison-Madueke was one of the most influential figures in Nigeria’s oil industry during her time in office and also served as president of the Organization of the Petroleum Exporting Countries between 2014 and 2015.
She stood trial alongside Olatimbo Ayinde, an oil industry executive accused of bribery offences linked to the case. The judgment brings to an end one of the most closely watched international corruption prosecutions involving a former Nigerian public official.
Background
British prosecutors charged Alison-Madueke in 2023 with five counts of accepting bribes and one count of conspiracy to commit bribery over the awarding of oil and gas contracts during her tenure as petroleum minister.
She relocated to the United Kingdom after the defeat of the People’s Democratic Party in Nigeria’s 2015 presidential election and has remained the subject of separate corruption investigations in Nigeria.
Nigerian courts have previously ordered the forfeiture of assets worth billions of naira linked to the former minister.
During the UK trial, prosecutors alleged that several Nigerian businessmen funded luxury expenses on her behalf, including purchases at Harrods and property renovations in London and Buckinghamshire.
The prosecution also alleged that she had access to luxury properties in London and surrounding areas.
Alison-Madueke denied the claims and told the court that official expenses incurred during government engagements were reimbursed by the Nigerian National Petroleum Corporation.
The Issues
- The challenge of prosecuting cross-border corruption cases involving former public officials.
- Questions around transparency and accountability in the management of oil sector contracts.
- Ongoing corruption-related proceedings involving former officials in multiple jurisdictions.
- The implications of the verdict for future international anti-corruption investigations.
What’s Next
- The acquittal concludes the UK criminal case against Alison-Madueke.
- Attention may shift to outstanding legal and asset recovery matters involving the former minister in Nigeria.
- Anti-corruption agencies in both countries are expected to review the implications of the verdict.
Bottom Line
A London jury has acquitted former Nigerian Petroleum Minister Diezani Alison-Madueke of all bribery charges, ending a decade-long British investigation into allegations that she received luxury benefits in exchange for influence over oil sector contracts.
