LONDON — Diezani Alison-Madueke, Nigeria’s former petroleum minister and the first female president of OPEC, was acquitted of all corruption charges by a London jury on Wednesday. The verdict deals a monumental blow to the UK’s National Crime Agency (NCA), which spent more than a decade investigating allegations against one of Africa’s most prominent political figures.
Following an exhaustive five-month trial at Southwark Crown Court and more than 46 hours of intense jury deliberations, the 65-year-old former minister was found not guilty on five counts of accepting bribes and one count of conspiracy to commit bribery. Her co-defendants, oil executive Olatimbo Ayinde and her brother Doye Agama, were also completely cleared.
The prosecution had painted a picture of a lavish “life of luxury” in London, funded by oil and gas executives looking to secure lucrative contracts within Nigeria’s state-owned petroleum sector between 2011 and 2015. British prosecutors pointed to eye-catching expenditures, including private jet flights, high-end real estate refurbishments, luxury goods from Harrods, and even high-value designer items. They argued that these perks were improper benefits extended to win her political favour.
However, Alison-Madueke mounted a fierce defence on the witness stand, presenting herself not as a corrupt official, but as a systematic reformer. She testified that she had actively fought against deeply entrenched, powerful “cabals” that had held the Nigerian oil industry hostage since colonial times. Her legal team successfully dismantled the prosecution’s case by arguing that the expenditures in question were either legitimate private loans or official expenses that had been fully reimbursed.
Furthermore, the defence highlighted that a “gross delay” of 11 years between her initial 2015 arrest and the final trial had severely compromised her ability to defend herself, noting that vital corroborating documents had vanished over the decade. Ultimately, the judge directed the jury that if they believed the expenses might have been properly reimbursed, they could not find her actions improper.
“For 11 long, gruelling years, this case has hung over my head and has tormented me and my family,” Alison-Madueke said in a statement released after the verdict. “But today, the past decade of relentless and unjust vilification, condemnation, and scrutiny has finally come to an end. My name is cleared. This nightmare is over.”
