Ex Nigerian Oil Minister Denies Influence in London Bribery Trial

A high profile corruption trial involving Nigeria’s former petroleum minister continued in London as her legal team argued she held little real power over the awarding of state oil contracts. Appearing at Southwark Crown Court, Diezani Alison-Madueke faces multiple charges relating to alleged bribery and conspiracy during her time in office between 2010 and 2015. Prosecutors allege that she benefited from a lavish lifestyle in the UK, including the use of luxury properties and expensive gifts supplied by figures in the oil and gas sector seeking influence. Her lawyer, however, told the court that she acted largely as a formal approver of decisions already made by officials, describing her role as limited and procedural rather than decisive. The defence maintains that the former minister did not personally control the contract process and lacked authority to steer outcomes in favour of any individual or company.

The court heard that Alison-Madueke disputes claims that she personally received extravagant benefits, with her lawyer stating that any spending attributed to her was later repaid. It was argued that arrangements were made on her behalf due to restrictions preventing Nigerian ministers from holding overseas bank accounts, rather than as part of any corrupt arrangement. The defence also challenged assertions about the extent of her use of high value properties in London, suggesting the prosecution had overstated both access and personal benefit. Alison-Madueke has pleaded not guilty to all charges, which include several counts of accepting bribes and one of conspiracy. The case has drawn significant attention due to her former senior role in Nigeria’s government and her international profile within the energy sector during that period.

The trial also involves two co defendants, including Alison-Madueke’s brother, who denies allegations linked to conspiracy, and another individual accused of making improper payments. Prosecutors argue that gifts and hospitality were provided with the intention of influencing decisions on valuable oil contracts, claims the defence strongly rejects. The proceedings are expected to continue for several weeks, with jurors set to hear extensive evidence about financial transactions, property use and decision making within Nigeria’s petroleum ministry. The case represents one of the most prominent foreign corruption trials heard in a UK court in recent years, highlighting London’s role as a venue for complex international legal cases involving alleged financial misconduct connected to global industries.
