Five counts of accepting bribes.One count of conspiracy to commit bribery.She has entered a not guilty plea to all charges.
The charges, brought by the UK’s National Crime Agency (NCA), allege that she received improper financial benefits from individuals and companies in exchange for influence over the awarding of multi-million-pound oil and gas contracts.

Other alleged benefits include the use of chauffeur-driven cars, private jet flights, and the payment of school fees for her son.Prosecutors claim she was given approximately £100,000 in cash as part of the alleged bribery scheme.
Alexandra Healy, prosecuting at Southwark Crown Court, told jurors that Alison-Madueke “enjoyed a life of luxury in London,” provided by individuals who “clearly believed she would use her influence to favour them” in state oil and gas contracts.
The prosecution has stated there is no direct evidence that contracts were awarded improperly, but argued it was improper for a public official to accept benefits from people doing business with government-owned entities.
Alison-Madueke is not the only defendant in the case. Also standing trial alongside her are:Olatimbo Ayinde, an oil industry executive facing related bribery charges.Doye Agama, Alison-Madueke’s brother, charged with conspiracy to commit bribery in connection with the case.
