UK Prosecutors Allege Diezani Alison-Madueke Lived Lavishly on Bribes as London Trial Begins

British prosecutors have accused former Nigerian oil minister Diezani Alison-Madueke of funding an extravagant lifestyle with bribes received during her time in office, as her long-awaited trial opened on Tuesday at Southwark Crown Court in London.

Alison-Madueke, 65, who made history as the first woman to serve as president of the Organisation of Petroleum Exporting Countries (OPEC), is facing multiple counts of bribery linked to her tenure as Nigeria’s Minister of Petroleum Resources between 2011 and 2015, under former President Goodluck Jonathan.

In court, prosecutors told the jury that individuals and companies seeking highly lucrative oil and gas contracts with Nigeria’s state-owned petroleum entities allegedly provided the former minister with significant financial and material benefits. According to the prosecution, these advantages were given in exchange for influence over contracts awarded by the Nigerian National Petroleum Corporation (NNPC) and its subsidiaries.

The court heard that Alison-Madueke is accused of accepting bribes from individuals connected to the Atlantic Energy and SPOG Petrochemical groups—companies that later secured major oil-related contracts. Prosecutors claim the alleged benefits went far beyond cash, painting a picture of what they described as a “life of luxury.”

Among the alleged inducements were £100,000 in cash, chauffeur-driven vehicles, private jet flights to Nigeria, and the refurbishment and staffing of multiple London properties. The prosecution also alleged that Alison-Madueke received expensive gifts, including school fees for her son, luxury items from brands such as Harrods and Louis Vuitton, and additional private jet travel.

Addressing the court, prosecutors stressed that as a senior government official, Alison-Madueke “should not have accepted benefits” from parties doing profitable business with government-owned oil entities.

Alison-Madueke, who served as OPEC president from 2014 to 2015, has faced legal scrutiny in several countries over the years. In Nigeria, courts seized properties linked to her in 2017, valued at several million dollars. Nigeria’s Economic and Financial Crimes Commission (EFCC) confirmed this week that there are still ongoing cases against her in the country.

She was first arrested in London in October 2015 and has remained on bail since then. In 2023, British authorities formally charged her with accepting bribes. At the time, the UK’s National Crime Agency (NCA) said it suspected she had abused her position to secure personal financial rewards tied to multi-million-pound oil contracts.

Also standing trial are Doye Agama, her brother, and Olatimbo Ayinde, both accused of playing roles in the alleged bribery scheme. Prosecutors noted that all three defendants had British addresses during the period covered by the charges.

Alison-Madueke has denied all allegations against her. The presiding judge, Justice Justine Thornton, indicated that the trial is expected to conclude by April 24, bringing renewed global attention to one of the most high-profile corruption cases linked to Nigeria’s oil sector.
