Verdict at Southwark Crown Court
On June 17, 2026, a jury at Southwark Crown Court in London acquitted Diezani Alison-Madueke, Nigeria’s former Minister of Petroleum Resources, of six charges of bribery. The verdict follows a grueling five-month trial brought by the UK’s National Crime Agency (NCA), which alleged that the former minister accepted financial advantages from oil industry figures between 2011 and 2015.
Defense and Prosecution Arguments
Prosecutors had alleged that Alison-Madueke, 65, maintained a “life of luxury” in London funded by individuals seeking lucrative contracts with Nigeria’s state-owned petroleum corporation. However, the defense successfully argued that the prosecution suffered from a “gross delay,” noting that the investigation had spanned over a decade since her initial arrest in 2015. Defense lawyer Jonathan Laidlaw stated that the delay prevented the defense from accessing critical evidence, including documents that could have established her innocence.
Broader Legal Implications
The acquittal of Alison-Madueke, who also served as the first female president of OPEC, marks a significant setback for the NCA’s efforts to prosecute high-level international corruption. Alongside the former minister, the court also acquitted oil executive Olatimbo Ayinde and Doye Agama, who were also facing charges related to the alleged bribery schemes. Alison-Madueke continues to face legal scrutiny in other jurisdictions, but this verdict concludes the primary UK-based criminal case that has dominated headlines for over ten years.
