British prosecutors opened their case against Diezani Alison-Madueke on Tuesday, alleging that the former Nigerian oil minister leveraged her position to fund a “life of luxury” through systematic bribery.
The 65-year-old, who made history as the first female president of OPEC, appeared at Southwark Crown Court for the first day of a trial centered on her conduct between 2011 and 2015. During this period, she served as Nigeria’s Minister for Petroleum Resources under the administration of then-President Goodluck Jonathan.
The Allegations: Contracts for Kickbacks
The prosecution contends that individuals seeking “lucrative oil and gas contracts” with the Nigerian National Petroleum Corporation (NNPC) provided Alison-Madueke with significant financial incentives.
As a high-ranking government official, the crown argues she was legally and ethically prohibited from accepting benefits from entities doing business with state-owned corporations.
Specific bribes alleged in court include:
- Cash & Staffing: Over £100,000 in cash, alongside covered costs for private staff and renovations at multiple London residences.
- Luxury Transport: Access to chauffeur-driven vehicles and private jet travel between London and Nigeria.
- High-End Lifestyle: School fees for her son, and designer goods from prestigious retailers like Harrods and Louis Vuitton.
Corporate Links and Co-Defendants
Prosecutors identified connections between the alleged bribes and figures associated with Atlantic Energy and SPOG Petrochemical. Both companies reportedly secured substantial contracts with the NNPC or its subsidiaries during Alison-Madueke’s tenure.
The trial is not limited to the former minister. Two others—her brother, Doye Agama, and Olatimbo Ayinde—are also facing prosecution on related bribery charges. All three defendants were listed with British addresses at the time the alleged offenses occurred.
A Global Legal Saga
Since her initial arrest in London in October 2015, Alison-Madueke has remained on bail while navigating a web of international legal challenges.
- Nigeria: Courts have already seized several million dollars worth of her properties. The Economic and Financial Crime Commission (EFCC) confirmed it maintains active cases against her.
- United States: Her financial dealings have previously drawn the scrutiny of American authorities.
- United Kingdom: The National Crime Agency (NCA) formally charged her in 2023, suspecting her of abusing her power to reward multi-million-pound contracts for personal gain.
Alison-Madueke has consistently denied all charges. Judge Justine Thornton indicated that the trial is expected to conclude by April 24, 2026.
