Mazher Mahmood (born 22 March 1963) is an undercover British journalist who was convicted of conspiracy to pervert the course of justice. Before his conviction, he worked mainly for the tabloid press. He spent 20 years working for the News of the World and the Sunday Times, during which time he was responsible for numerous investigations, including a reputed 94 that led to convictions. He won Reporter of the Year in 2011, as well as Scoop of the Year and the Sports Journalists' Association award, for an investigation of cricket match-fixing. Later, from its foundation in 2012, he worked for the Sun on Sunday, successor to the News of the World. Mahmood became known popularly as the "fake sheikh" because he often posed as a sheikh during the course of his investigations. In addition to numerous highly regarded public-interest investigations, he attracted allegations of breaking the law without any clear public-interest justification, including several episodes in which he was accused of entrapment. In July 2014, Mahmood was suspended from the Sun on Sunday after a trial collapsed against former X Factor judge and singer Tulisa, with concerns voiced by a judge that Mahmood might have perjured himself. In October 2016, Mahmood was jailed for 15 months after being found guilty of conspiring to pervert the course of justice.
