Oil executives deny bribing former Nigerian minister in London court

I don't think anyone would risk their career for furniture and handbags
Alison-Madueke's response when confronted with allegations of expensive purchases prosecutors claim were made on her behalf.

In a London courtroom, the machinery of accountability grinds forward as two oil executives, absent in person but present through their written words, deny that luxury and influence were ever exchanged as currency between them and a former Nigerian minister. Diezani Alison-Madueke, once among the most powerful figures in African energy, now faces five bribery charges and a conspiracy count — her defense resting on the argument that what looked like corruption was either repaid debt or the ordinary friction of doing official business across borders. The trial raises a question as old as power itself: where does patronage end and corruption begin?

  • A former Nigerian oil minister sits at the center of a sprawling bribery trial, accused of trading her influence for private jets, luxury apartments, and shopping sprees at Harrods — a life allegedly bankrolled by the oil industry.
  • Two oil executives, speaking only through statements read by their lawyers, flatly deny any wrongdoing — one claiming he was repaid in cash for a department store bill, the other citing Nigeria's foreign currency difficulties as the reason he bought goods on the minister's behalf.
  • Former president Goodluck Jonathan lent weight to the defense by testifying that third-party payments for ministers on overseas duty were standard practice, properly recorded, and sometimes personally approved by him.
  • Alison-Madueke, after nearly eleven days on the witness stand, insists she never traded favors for gifts, arguing that no one would risk a career over furniture and handbags — and that seized documents and political hostility from Nigerian authorities have crippled her ability to defend herself.
  • The trial now turns on whether a pattern of expensive transactions represents systematic corruption or the messy, informal economics of high-level government service.

Inside Southwark Crown Court, the defense in the trial of former Nigerian oil minister Diezani Alison-Madueke pressed its case through the written statements of two absent oil executives. Kevin Okyere, a Ghanaian businessman, told investigators he had simply covered a £3,900 bill for Alison-Madueke at a London department store after she came up short at the till — and that she later repaid him in cash in Abuja. Igho Sanomi, a Nigerian tycoon, offered a structural explanation: foreign currency was hard to obtain in Nigeria, so he purchased items on her behalf in London with the expectation of reimbursement, and insisted his companies won their contracts through fair competition, not ministerial favor.

Alison-Madueke, 65, faces five charges of accepting bribes and one of conspiracy to commit bribery. The prosecution paints a portrait of a minister whose lifestyle — private jets, luxury apartments, chauffeur-driven cars, and lavish shopping — was quietly subsidized by oil executives seeking her influence. She denies it all, and her defense received unexpected support from former president Goodluck Jonathan, who testified that third-party payments for ministers on official overseas travel were routine, recorded, and sometimes personally sanctioned by him.

Having spent nearly eleven days on the witness stand — six of them under cross-examination — Alison-Madueke was confronted with a catalogue of expensive purchases, including £170,000 spent at a London antiques shop in a single visit. She denied the items were for her personal benefit. "I don't think anyone would risk their career for furniture and handbags," she told the court.

She also argued that her defense has been undermined by forces outside the courtroom: held in London since her 2015 arrest, she claims Nigerian authorities seized her documents and have refused to assist her case due to political opposition to the government she served. Also on trial are her brother, former archbishop Doye Agama, and oil executive Olatimbo Ayinde, both denying their respective charges. The court continues to weigh whether what happened was corruption — or simply the cost of doing official business.

Inside Southwark Crown Court on a Tuesday in late April, the defense mounted its counterattack. Two oil executives—Kevin Okyere, a Ghanaian businessman running several oil and gas companies, and Igho Sanomi, a Nigerian tycoon—were not present to speak for themselves. Instead, their written statements to investigators were read aloud by their lawyers, each man flatly denying he had ever paid bribes to Diezani Alison-Madueke, the former Nigerian oil minister now on trial for accepting them.

Alison-Madueke, 65, stands accused of living a life bankrolled by the oil industry—private jets, luxury apartments worth millions, chauffeur-driven cars, shopping sprees at Harrods and other high-end London stores. The prosecution alleges that oil executives paid for all of it as a way to secure her favor and influence. She denies every count: five charges of accepting bribes, plus conspiracy to commit bribery. Her defense rests on a simple claim: the money was either repaid or never hers to begin with.

Okyere's account, given to National Crime Agency investigators in June 2016, offers a mundane explanation for at least one transaction. He said he had encountered Alison-Madueke at the tills of Peter Jones, a London department store, two years earlier. She did not have enough money to cover her purchase. He paid £3,900 on her behalf. Later, he told investigators, she reimbursed him in cash at his office in Abuja. He called the bribery allegation "completely untrue." Sanomi offered a different rationale. In his June 2017 statement, he explained that foreign currency exchange was difficult in Nigeria, so he obtained items on Alison-Madueke's behalf in London, with the understanding they would all be reimbursed. He also insisted his companies won contracts through fair bidding, never through her intervention.

Former Nigerian president Goodlook Jonathan, who appointed Alison-Madueke as oil minister in 2010, provided testimony that framed the entire arrangement as routine. In his statement read to the court, Jonathan said it was not unusual for third parties to make payments on behalf of ministers traveling on official business. Such assistance, he said, would be recorded and reimbursed where applicable. He had even approved her use of private jets on some foreign trips.

Alison-Madueke herself had just finished nearly eleven days on the witness stand. Under six days of cross-examination by prosecutor Alexandra Healy KC, she had been confronted with a catalog of expensive items: Gucci handbags, furniture, Venetian lamps and vases. In November 2013, prosecutors alleged, she spent £170,000 at Vincenzo Caffarella, an antiques and decorative arts shop in London, buying what they described as a vast amount of property. She denied the items were for her, saying most were not. "I don't think anyone would risk their career for furniture and handbags," she told the court.

Her defense has been hampered, she claims, by circumstances beyond her control. Since her arrest in 2015, she said, she has been held in London at taxpayer expense and has not been allowed to return to Nigeria for ten years. The Nigerian authorities, she alleged, seized her papers and have refused to assist her defense because of their political opposition to the government she served. She denied lying about the spending. "At no time did I do anything to influence or show favour to anyone," she said.

Also on trial is her brother, former archbishop Doye Agama, 69, who denies conspiracy to commit bribery and will not be giving evidence. Oil industry executive Olatimbo Ayinde, 54, denies one count of bribery related to Alison-Madueke and a separate count of bribery of a foreign public official. The trial continues, with the court still weighing whether the spending was corruption or simply the cost of doing business on official duty.

Why would an oil executive pay for someone's shopping at Peter Jones and then accept cash repayment? That seems like an odd way to launder a bribe.

Model

That's the defense's point exactly—it's too obvious, too traceable. If you're actually bribing someone, you don't create a paper trail of department store receipts and cash handovers. You hide it.

Inventor

But the prosecution presumably has evidence these payments happened. What's their theory about why?

Model

That the executives were buying access and favor. When you're an oil company trying to win contracts in Nigeria, having the oil minister in your debt is valuable. The question is whether these were gifts meant to influence her, or legitimate expenses she repaid.

Inventor

And the currency exchange argument—is that plausible?

Model

It's plausible enough that a former president testified it was standard practice. But the prosecution will argue that's convenient cover. Why would a minister need oil executives to buy her Venetian lamps and Gucci handbags because of currency problems?

Inventor

What about her claim that she's been blocked from returning to Nigeria for ten years?

Model

That's a real problem for her defense. If the documents that would prove repayment are in Nigeria and she can't access them, she's fighting with one hand tied. It's a credibility issue either way—either the documents exist and she's being prevented from proving her case, or they don't exist and she's making excuses.

Inventor

So what does the jury have to decide?

Model

Whether this was corruption or just the messy reality of how business gets done when a minister travels abroad. The law says one thing; the defense is arguing the practice was normal and properly accounted for.
