…Acquittal after 11-year legal ordeal revives debate over Buhari-era anti-corruption “prosecutions”
By Chike Ofili
Former Minister of Petroleum Resources, Diezani Alison-Madueke, on Wednesday walked free from a London courtroom after a jury acquitted her of all six corruption charges brought against her by British authorities, ending what she described as an 11-year nightmare that began shortly after the election of former President Muhammadu Buhari in 2015.
The verdict, delivered at Southwark Crown Court after more than 46 hours of jury deliberations, marked the collapse of one of the most publicised corruption cases involving a former Nigerian public official.
Alison-Madueke, who served as petroleum minister under former President Goodluck Jonathan from 2010 to 2015, had faced five counts of accepting bribes and one count of conspiracy to commit bribery. British prosecutors alleged that she received luxury benefits, including private jet travel, holidays and access to high-end London properties from oil industry figures seeking contracts in Nigeria.
She denied all the allegations, insisting throughout the proceedings that she neither accepted bribes nor abused her office.
The jury agreed, acquitting her on all counts.
“For 11 long, gruelling years this case has hung over my head and tormented me and my family,” she said after the verdict. “My nightmare is over.”
The ruling closes a chapter that began almost immediately after Buhari assumed office on a promise to wage war against corruption. Within months of the change of government, Alison-Madueke became one of the most prominent targets of anti-graft investigations launched by the new administration.
Yet, despite years of investigations, arrests, forfeiture proceedings, and international cooperation involving authorities in Nigeria, Britain, and the United States, neither the Buhari administration nor anti-corruption agencies ever publicly identified a specific act of theft allegedly committed by the former minister, the precise funds allegedly stolen, or the exact sources from which such funds were allegedly taken.
Instead, the allegations against her evolved into a sprawling web of investigations, asset seizures, and prosecutions involving numerous associates, relatives, business figures, and public officials said to have had connections with her.
Critics of the Buhari administration argued at the time that the government appeared more focused on securing forfeitures, arrests, and public convictions in the court of public opinion than establishing, through criminal trials, precisely what Alison-Madueke had personally stolen and how.
Supporters of the government, on the other hand, maintained that the investigations formed part of a broader anti-corruption campaign aimed at recovering public assets and dismantling entrenched networks of corruption.
The former minister consistently rejected the allegations against her, describing them as politically motivated and accusing authorities of seeking to demonise selected individuals associated with the Jonathan administration.
At various stages, she complained that investigations were built on assumptions rather than evidence and that people connected to her were subjected to arrests, interrogations, and prosecutions in what she viewed as an effort to pressure them into making statements against her.
During her London trial, her defence team alleged missing evidence, investigative irregularities, and selective prosecution. Alison-Madueke told jurors she had been informed that she would be made a “scapegoat” after the 2015 change of government.
Her acquittal has once again intensified scrutiny of the anti-corruption methods employed during the Buhari years.
Ironically, one of the principal officials who championed the legal pursuit of Alison-Madueke, former Attorney-General of the Federation Abubakar Malami, is now facing his own legal troubles. As Attorney-General, Malami had defended the government’s strategy, arguing that there was no need to bring Alison-Madueke back to Nigeria because British authorities were already investigating her and that parallel proceedings could jeopardise the UK case.
Today, Malami himself is standing trial on charges relating to alleged wide-scale corruption and the exercise of his powers while in office, allegations he has denied.
The reversal has not been lost on political observers. Eleven years ago, Alison-Madueke was portrayed by the Buhari administration as one of the principal symbols of alleged corruption under the previous government. Today, she stands acquitted by a British court, while some of the key figures who drove the anti-corruption campaign face accusations of abuse of office and selective application of justice.
Her acquittal does not automatically terminate proceedings pending in Nigeria, where several EFCC-related matters and forfeiture cases remain before the courts. Nor does it erase years of allegations that have shaped public perceptions of her tenure as petroleum minister.
What it does do, however, is leave unanswered a question that has lingered since 2015: after more than a decade of investigations across multiple jurisdictions, what exactly did Diezani Alison-Madueke steal, from where was it stolen, and why has no court succeeded in proving it?
For Alison-Madueke, Wednesday’s verdict provided her own answer to that question. After eleven years of investigations, prosecutions and relentless public scrutiny, she emerged from court not as a convicted corrupt official but as a woman cleared of every criminal charge brought against her.
“My nightmare is over,” she said.
