Diezani Alison-Madueke

Diezani Alison-Madueke, a former Nigerian Minister of Petroleum Resources (2010–2015) and former OPEC President, has been the subject of numerous corruption allegations, civil asset forfeitures, and criminal indictments. In June 2026, Alison-Madueke was acquitted by a London jury at Southwark Crown Court of all five counts of accepting bribes and one count of conspiracy to commit bribery. Prosecutors had alleged she received luxury goods, property refurbishments, and cash from oil executives in exchange for influence over government contracts. Alison-Madueke maintained her innocence throughout, arguing that she was a target of political bias and that the alleged benefits were either standard third-party support or not accepted as bribes. Despite the UK acquittal, she remains the subject of extensive ongoing legal action in Nigeria. Key allegations and developments include: Criminal Charges: She faces multiple criminal charges in Nigeria, including money laundering and alleged involvement in a $1 billion oil deal. Nigerian authorities have secured arrest warrants and sought her extradition since 2020. She has also faced a Senate indictment (2009) regarding the improper transfer of N1.2 billion and allegations involving the loss of billions of dollars from the Nigerian National Petroleum Corporation. Asset Forfeiture: Nigerian and international courts have ordered the forfeiture of numerous assets linked to her. This includes the seizure of over 80 properties in Nigeria, $40 million worth of jewelry, and $153 million in cash. In 2023, the U.S. Department of Justice resolved civil forfeiture cases against her and associates, leading to the 2025 repatriation of approximately $53 million to Nigeria. She has denied these allegations, characterizing the proceedings as politically motivated. In 2023, she initiated a N100 billion libel suit against the Economic and Financial Crimes Commission (EFCC) regarding the publicity surrounding the seized assets. She has consistently cited medical treatment in the UK as the reason for her absence from Nigerian court proceedings.
