Nigeria’s former petroleum minister faces six charges at Southwark Crown Court. An EFCC operative has testified via video link from Abuja. The trial is scheduled to conclude by April 24, 2026. KEHINDE ADEGOKE writes.
On January 26, 2026, Diezani Alison-Madueke — once Nigeria’s most powerful woman, the first female president of OPEC, and the minister who presided over Nigeria’s oil revenues at their most lucrative peak — walked into the dock at Southwark Crown Court in London and pleaded not guilty to six criminal charges. She has been on bail in Britain since October 2015. The trial, originally expected to last 10 to 12 weeks, is now approaching its final phase. A verdict could come before the end of April.
TheDiggerNews.Com has reviewed the available court records, prosecution filings, and EFCC testimony to compile the most comprehensive Nigerian account of where this trial stands — and what its outcome means for a country still waiting for responsibility.
The charges, stated plainly:
R v Diezani Alison-Madueke — charges as filed, Southwark Crown Court
Five counts of accepting bribes — luxury goods, property use, cash payments, private jets, school fees — from oil industry figures seeking NNPC contracts between 2011 and 2015.
One count of conspiracy to commit bribery — working with intermediaries, including businessman Kolawole Aluko, to receive a financial advantage in exchange for ministerial influence.
Co-defendants: Olatimbo Ayinde (oil executive, 2 bribery counts) and Doye Agama (her brother, former archbishop, conspiracy charge — linked to £1m in payments to his church).
Lead prosecutor Alexandra Healy KC opened the Crown’s case with the language that should make every Nigerian citizen take notice. Alison-Madueke, she told the 12-person jury, “enjoyed a life of luxury in London” bankrolled entirely by oil and gas operators who believed she would use her ministerial influence to steer contracts their way.
“It was improper for Alison-Madueke to receive financial and other advantages from people with substantial interests in the oil industry who profited from government-generated business,” Healy told the court. “There is an important public interest in making sure that conduct in our country does not further corruption in another country.”
The specifics of the alleged bribes are staggering. Prosecutors say she received: over £2 million in luxury goods purchased at Harrods by Kolawole Aluko‘s bank cards; £370,740 at Marylebone antiques dealer Vincenzo Caffarella; £117,224 at Mayfair fine china specialist Thomas Goode; access to high-end London properties including a home in Buckinghamshire and a £2.8 million residence in Marylebone; full household staff — housekeeper, nanny, gardener, window cleaner; a private jet flight to Nigeria; chauffeur-driven cars; £100,000 in cash; and private school fees for her sons. A court witness who worked at Thomas Goode recalled Alison-Madueke saying during one shopping visit: “I don’t even know why I’m buying this. I haven’t got the room for it.”
The Evidence That Could Convict Her
The prosecution’s most devastating exhibit is a set of intercepted telephone conversations obtained by US prosecutors, in which Alison-Madueke’s own voice undermines every line of her defence.
“We stuck our necks out regarding the SAA and supported it.” — Diezani Alison-Madueke, in an intercepted call with Aluko and Omokore, on the Strategic Alliance Agreements that the Central Bank of Nigeria later determined were designed to funnel state oil income into private hands.
In a separate intercepted call, after Kolawole Aluko purchased the infamous Galactica Star — an $82 million superyacht later seized by US authorities — Alison-Madueke reportedly told him and his associate to “be a bit more careful,” not out of any moral concern, but because the ostentatious spending might attract scrutiny. The prosecutor’s framing of this moment is precise: “She was not a whistleblower. She was the risk manager.”
In another call introduced in evidence, she was recorded saying: “I will be happy to escort all of you to jail along with myself.” Prosecutors say this reflects consciousness of guilt. Her defence says it was an expression of speech.
Court testimony has also detailed that, in December 2014, Alison-Madueke allegedly instructed a former banker to transfer $153,310,000 from a government agency’s account, with explicit instructions that the funds should neither be credited to any identifiable account nor captured on any transaction platform.
Nigeria Testifying Against Her — From Abuja
The Nigerian government is cooperating with UK prosecutors. It is not peripheral. It is clear.
On February 26, 2026, EFCC operative Chinedu Eneanya testified virtually from the Federal High Court in Abuja, giving evidence to the Southwark Crown Court jury via video link under the Mutual Assistance in Criminal Matters Act 2018. Justice James Omotosho presided in Abuja; Justice Thornton presided in London. Both courts were simultaneously in session for the same criminal trial.
Eneanya confirmed that the EFCC received a UK request to review documents recovered during a 2015 raid on Alison-Madueke’s residence in Nigeria — but that his team began examining them only in December 2025, a decade after the raid. Under cross-examination, he confirmed he was not part of the first search team and had no prior involvement with the exhibits. The defence used this to suggest the EFCC’s evidence was belated and potentially compromised by the passage of time.
Four other Nigerian witnesses also testified virtually in earlier court sessions. The cooperation between Abuja and London on this case — formally structured, legally binding, and operating under a treaty — is the most consequential mutual legal assistance Nigeria has engaged in for any corruption case in its history. It is receiving almost no coverage in the Nigerian press.
The Defence: “She Was Just A Rubber Stamp”
Alison-Madueke’s lead defence counsel, Jonathan Laidlaw, has built a two-track counter-narrative. The first track is structural: that she lacked real decision-making power over contract awards, that the Nigerian ministerial system required her to ratify recommendations from below, and that she was therefore a “rubber stamp” rather than an architect of corruption. Her lawyers have told the court that payments were made on her behalf because “Nigerian ministers are forbidden from having bank accounts abroad” and that the payments were subsequently reimbursed — an argument the prosecution contests.
The second track is accurate: that Alison-Madueke was not physically present in the United Kingdom on the very days Kolawole Aluko’s cards were used at Harrods and elsewhere. Travel records, passport stamps, and itineraries were presented to show she was abroad during the alleged gift-receiving periods. This is the defence’s sharpest move — directly attacking the prosecution’s theory that she was the knowing, present recipient of the luxury spending.
The prosecution’s response is the intercepted calls. An innocent bystander, prosecutors argue, does not advise co-conspirators on managing the optics of their spending from 30,000 feet. Whether she was physically in the shops is a different question from whether she was the intended beneficiary and active participant.
The $53 million: where did it go?
In March 2023, the US Department of Justice announced the repatriation of over $53 million in forfeited assets linked to the Alison-Madueke corruption probe — luxury apartments in New York and California, and the Galactica Star superyacht. These were proceeds of the alleged fraud returned to Nigeria under a formal agreement between Washington and Abuja.
TheDiggerNews.Com asks the question that no Nigerian outlet has pursued: where exactly are those funds now? What account were they deposited into? What ministry or agency controls them? Has any of it been deployed for any public purpose? The repatriation was announced with considerable fanfare. The accountability trail afterwards has been silent.
This is not an academic question. The US indictment calculated that Alison-Madueke’s alleged scheme cheated Nigeria of oil revenues exceeding the amount recovered. If the $53 million has been absorbed into Nigeria’s fiscal system without a trace, it is a secondary scandal attached to the primary one.
What A Conviction — Or Acquittal — Means For Nigeria
If Justice Thornton’s jury returns a guilty verdict, Alison-Madueke faces up to 10 years in a British prison and an unlimited fine. More importantly for Nigeria, a conviction would formally establish in law what has long been alleged in evidence: that her ministry operated as a pay-to-play machine, that oil contracts worth hundreds of millions were steered to connected businessmen in exchange for personal luxury, and that Nigeria’s oil wealth — produced at its highest global price peak — was systematically plundered from within the ministry that was supposed to safeguard it.
An acquittal would not establish innocence so much as raise questions about the prosecution’s evidence. The intercepted calls would remain. The asset trail would remain. The Strategic Alliance Agreements, which the Central Bank of Nigeria determined were designed to funnel state income into private hands, would remain on the public record.
Either way, the trial has already produced more publicly documented evidence of how Nigeria’s petroleum ministry operated between 2010 and 2015 than any Nigerian parliamentary inquiry or EFCC prosecution has managed in eleven years.
The Questions Nigeria Must Ask — Whoever Wins
The EFCC must publicly account for why documents seized from Alison-Madueke’s residence in October 2015 were not examined until December 2025 — a decade later — and only then at the request of the UK. What was being done with those documents for ten years?
The Federal Ministry of Finance must publicly account for the $53 million repatriated from the United States in 2023, the account it was received into, who controls disbursement, and what public purpose, if any, it has been applied to.
The Office of the Attorney-General of the Federation must explain whether Nigeria has or intends to file its own criminal charges against Alison-Madueke — and if not, why a country that lost billions to alleged ministerial corruption is content to let another country prosecute the case while remaining silent about the proceeds already returned.
And the Nigerian public deserves a direct answer to the simplest question of all: while British taxpayers fund the prosecution of a woman who allegedly looted Nigeria’s oil ministry, what has the Nigerian government done — beyond cooperating when asked — to bring its own case?
