LONDON — After nearly 11 days on the witness stand, Nigeria’s former Minister of Petroleum Resources, Diezani Alison-Madueke, has closed her defence at the Southwark Crown Court. The trial reached a boiling point during the final hours of cross-examination as the former minister stood her ground against a series of corruption allegations.
The proceedings took an unexpected turn when the lead prosecutor appeared to lose composure during a heated exchange. Tension peaked as the prosecution attempted to dismantle Alison-Madueke’s denials regarding the source of her luxury lifestyle while in office. Observers noted visible frustration from the Crown’s legal team as the defendant countered suggestions that her high-end acquisitions were the proceeds of crime.
Throughout her testimony, Alison-Madueke remained firm, strongly denying all allegations of bribery, abuse of office, and the receipt of luxury benefits. She maintained that the private jets, Harrods shopping sprees, and high-end properties linked to her by the National Crime Agency were either official logistics or the result of her personal wealth and family background, rather than kickbacks for oil contracts.
The former minister argued that her role in the petroleum ministry was policy-driven and that the awarding of multi-billion dollar contracts followed established institutional processes. She dismissed the prosecution’s claims as a mischaracterisation of her official duties and personal associations with Nigerian businessmen.
With the defence now closed, the court is moving toward closing arguments. The jury will soon decide whether the once-powerful minister was the architect of a massive bribery scheme or the victim of a politically motivated investigation.
