As a protracted corruption case officially enters trial proceedings, a former Nigerian petroleum minister and former president of the Organisation of the Petroleum Exporting Countries is scheduled to appear in a London court on Monday.
Diezani Alison-Madueke, 65, is accused of six bribery charges related to her tenure as former President Goodluck Jonathan’s oil sector manager from 2010 to 2015. She has entered a not guilty plea to every accusation.
This week will see the start of preliminary hearings in the case, which has been under investigation for almost ten years. These hearings will include procedural issues and jury selection. When the trial is well underway, the court is anticipated to hear a great deal of evidence. When the court hearings started last week, Alison-Madueke was there.
According to British prosecutors, Alison Madueke had considerable control over Nigeria’s petroleum business, one of the most profitable in Africa, and took bribes over a four-year period between 2011 and 2015.

She was formally prosecuted by the UK’s National Crime Agency in 2023 after it was thought that she had abused her position to obtain financial benefits in exchange for giving oil contracts worth millions of pounds.
Alison-Madueke allegedly received at least 100,000 pounds ($127,000) in cash as well as a variety of luxuries, such as private jet travel, chauffeur-driven cars, and the use of upscale London apartments, according to the prosecution. Allegations of expensive furnishings, home remodelling, private school tuition, and designer goods, including those from high-end fashion labels, are also mentioned in court filings.
According to authorities, the purported advantages were given by people looking for preferential treatment in contracts and strategic choices pertaining to Nigeria’s petroleum industry, which brings in billions of dollars every year.
Due to her high ranking in the administration and the extent of the alleged wrongdoing, Alison Madueke has been under constant scrutiny since her initial arrest in London in October 2015 and her extended release on bail during the inquiry.
As the nation’s first female petroleum minister and the first female head of OPEC, she has a significant place in Nigerian political history.
In addition to her, two other accused are on trial. Olatimbo Ayinde attended in person, while Doye Agama appeared in court via video link. Both are charged with bribes related to the case.
The anticipated duration of the experiment is 10–12 weeks.
