Former Minister of Petroleum Resources, Diezani Alison-Madueke, has once again appeared before a London court as prosecutors continue laying out evidence in an ongoing corruption and bribery case with far-reaching international consequences.
British prosecutors allege that Alison-Madueke accepted cash payments and luxury privileges in return for exerting influence over oil and gas deals. She has, however, firmly denied all allegations brought against her.
On Monday, members of the jury heard evidence from a luxury home furnishings retailer and a former housekeeper, as the prosecution attempted to demonstrate how expensive purchases and the use of properties were allegedly channelled through third parties linked to the former minister.
The 65-year-old is facing several counts of bribery following an investigation that spanned multiple years. The alleged crimes are said to have taken place between 2011 and 2015, during her tenure as Nigeria’s petroleum minister, a period when she also maintained a residence in the United Kingdom.
The UK National Crime Agency (NCA), which focuses on combating serious and organised international crime, claims that the alleged bribes were received on British soil.
Prosecutors accuse Alison-Madueke of accepting “financial or other advantages” from individuals connected to the Atlantic Energy and SPOG Petrochemical groups. According to the Crown, both firms were awarded lucrative contracts with the Nigerian National Petroleum Corporation (NNPC) or its subsidiaries during her time in office.
The court heard that the former minister allegedly benefited from £100,000 ($137,000) in cash, chauffeur-driven vehicles, private jet travel to Nigeria, and refurbishment works alongside staffing expenses at multiple London properties.
Additional charges relate to claims that she received payment of school fees for her son, luxury goods from high-end retailers including London’s Harrods and Louis Vuitton, as well as further private jet flights.
Alison-Madueke, who also served as President of the Organisation of Petroleum Exporting Countries (OPEC) between 2014 and 2015, has been entangled in several legal proceedings across different jurisdictions, including the United States.
She has remained on bail in the UK since her arrest in October 2015. In 2023, British authorities formally charged her with bribery offences, allegations she continues to reject.
What you should know
Diezani Alison-Madueke’s London trial represents one of the most prominent international corruption cases involving a former Nigerian public official.
Prosecutors argue that she leveraged her position as oil minister to receive cash and luxury benefits tied to energy contracts, while she maintains her innocence.
The outcome of the case could have major implications for cross-border anti-corruption enforcement and asset recovery efforts linked to Nigeria’s oil sector.
