Former Nigerian petroleum minister Diezani Alison-Madueke has denied charges that she accepted bribes during her time in office, according to court proceedings in the United Kingdom.

Alison-Madueke, who served as Nigeria's Minister of Petroleum Resources from 2010 to 2015 under President Goodluck Jonathan, is accused by prosecutors of receiving payments from oil industry figures in exchange for favorable treatment.

Prosecutors allege that Alison-Madueke used the proceeds from these payments to fund "a life of luxury" in the UK, including purchasing and renovating high-end properties. The specific details of the properties and their locations have not been disclosed in court filings.

The former minister has maintained her innocence throughout the proceedings. Alison-Madueke previously faced corruption investigations in Nigeria related to her tenure overseeing the country's crucial oil sector, which accounts for the majority of government revenues.

The case represents part of ongoing international efforts to pursue corruption cases involving former Nigerian officials. Nigeria's oil ministry oversees one of Africa's largest petroleum industries, making the position one of significant influence in the country's economy.
