Diezani Alison-Madueke was Nigeria's minister of petroleum resources from 2010 to 2015A Nigerian oil minister went on "extravagant and excessive" spending sprees at high-end London stores with money from bribes by industry insiders, a London court has heard. The prosecution alleges that between October 2012 and November 2013, Aluko bought various items, including lamps and tables, for Alison-Madueke costing more than £370,000. The court was told items were often bought but not collected, and that Alison-Madueke never paid for anything herself. In a conversation in May 2014, Alison-Madueke told Aluko she was really annoyed, given that she and others had "stuck our necks out" when negotiating oil mining leases. The payments were intended to "induce Alison-Madueke to perform her duties as the Nigerian minister of petroleum resources improperly," lawyers told the court.
