UK says Nigerian's conviction stands despite bribery evidence

By Estelle Shirbon LONDON (Reuters) - Jailed former Nigerian state governor James Ibori's convictions remain valid despite evidence a British police officer took bribes during the investigation of his case, Britain's state prosecution agency said on Thursday. Ibori, who as governor of oil-producing Delta State from 1999 to 2007 was one of Nigeria's most powerful men, is serving a 13-year sentence in a British prison after pleading guilty in 2012 to 10 counts of fraud and money-laundering.
