More than £2m was spent at Harrods on behalf of a then-Nigerian oil minister Diezani Allison-Maduekwe accused of accepting bribes from industry figures interested in government contracts, a court in London has heard.

Diezani Alison-Madueke, 65, is alleged to have been provided with “a life of luxury in the United Kingdom”, including the use of multimillion-pound properties, a chauffeur driven car, travel by private jet, and £100,000 in cash.

Other benefits she allegedly received included £4.6m spent on refurbishing properties in London and Buckinghamshire, the trial at Southwark Crown Court was told.

She denies five counts of accepting bribes and a charge of conspiracy to commit bribery.

Alison-Madueke was minister of petroleum resources between 2010 and 2015 under then-President Goodluck Jonathan.

Jurors were told that over £2m was spent on behalf of Alison-Madueke at Harrods using the payment cards of Nigerian businessman Kolawole Aluko and the debit card of his company Tenka Limited.

The defendant had her own personal shopper at the store, only available to Harrods Rewards Black Tier members who must spend over £10,000 a year, the court heard.

Jurors were also told she lived some of the time in the UK where she was provided with a housekeeper, nanny, gardener and window cleaner.

The salaries and other running costs were paid for by the owners of energy companies who had lucrative contracts with the state-owned Nigerian National Petroleum Corporation, the court was told.
