Mazher Mahmood

After Mahmood was charged, the Crown Prosecution Service announced its intention to review more than 30 criminal trials in which he had given evidence. On 21 October 2016, Mahmood was jailed for 15 months after being found guilty of evidence tampering.

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.

On 21 July 2014 the trial of the R&B singer-songwriter and former X-Factor judge Tulisa Contostavlos, brought about by a Mahmood drugs sting operation, collapsed.

Mahmood was the subject of BBC television Panorama investigation. The Fake Sheikh Exposed, broadcast on 12 November 2014, was presented by John Sweeney and produced by Meirion Jones and Owen Phillips. The programme aired despite legal efforts by Mahmood to prevent recent pictures of himself being shown, and a request from the Attorney General to stop the broadcast. The programme included allegations that Mahmood's methods included payments to third parties who procured the drugs that his targets would later be exposed as supplying, and that he made offers of scarcely believable career opportunities to targets with no recent history of drug misuse, who were then pressured to obtain him cocaine.

On 4 December 2014, the Crown Prosecution Service investigated 25 cases where Mahmood gave evidence. On 29 September 2015, it announced that Mahmood and his former driver Alan Smith had been charged with conspiracy to pervert the course of justice. The offences concern evidence given in the trial of R&B singer-songwriter Tulisa Contostavlos. The pair appeared at Westminster Magistrates' Court. on 20 November 2015. Following a trial at the Old Bailey, Mahmood and Smith were found guilty of conspiring and intending to pervert the course of justice. On 21 October 2016, Mahmoud was sentenced to 15 months and Smith received a suspended sentence of 12 months.

In January 2013, Mahmood was nominated for the Services to Media award at the British Muslim Awards.

Mahmood won Reporter of the Year again in 2011, as well as Scoop of the Year, for an investigation of cricket match-fixing. He also picked up the Sports Journalists' Association award in 2011 for the same story.

In May 2010, Mahmood exposed snooker player John Higgins and his agent Pat Mooney for apparently agreeing to fix the outcome of future individual frames which would not necessarily alter the course of a match. Meeting in a hotel room in Kiev, Ukraine, on the morning of Friday 30 April, where Higgins and his manager had travelled after his exit from the 2010 World Championship, to ostensibly meet the undercover News of the World team the newspaper described as men posing as businessmen interested in organising a series of events linked to the World Series of Snooker. On video, Higgins and Mooney discussed how to throw frames. On the publication of the story on Sunday 2 May, Barry Hearn, Chairman of the WPBSA, immediately suspended Higgins from WPBSA tournaments, promising a full investigation, saying "Those responsible, if proved, will be dealt with in a very harsh and brutal way. People have a right to see pure sport – that's what I want snooker to be." Mooney resigned from his post as director of the WPBSA and was later banned from snooker management for life, following an investigation and judgement, which also resulted in John Higgins being given a ban and large fine. Explaining that "it is not enough to just have integrity in such a position, you must also be seen to have integrity", he explained further that "this was not possible given the manner in which this allegation has been reported". Higgins subsequently issued a statement denying he had ever been involved in match fixing, and said of the meeting, "I didn't know if this was the Russian mafia or who we were dealing with. At that stage I felt the best course of action was just to play along with these guys and get out of Russia." Mooney also said "we were genuinely in fear for our safety".

Mahmood's name came under the limelight once again when, in August 2010, he posed as an Indian businessman to expose the cricket bookie Mazhar Majeed who claimed Pakistani cricketers Mohammad Amir, Mohammad Asif, Salman Butt and Kamran Akmal had committed spot-fixing during Pakistan's 2010 tour of England; the team was accused of deliberately bowling three no-balls, in an incident that veteran Richie Benaud described as the most distressing revelation in his 52 years of watching cricket.

In September 2008, he wrote a book entitled Confessions of a Fake Sheik – The King of the Sting Reveals All.

Mahmood's only face-to-face televised interview was in 2008 with the BBC's Emily Maitlis on The Andrew Marr Show.

On 30 March 2006, Respect party politician George Galloway said that Mahmood, using his "fake sheikh" disguise and working for the News of the World, attempted to trap him in a sting operation at a meeting in the Dorchester Hotel with businessmen from the Middle East. Galloway said he had put off the meeting for several weeks and was suspicious from the beginning. Of the men, he wrote on his website that "neither of the two looked at all like an Islamist (which is what they later claimed to be); neither had a beard".

In January 2006, Mahmood met England head coach Sven-Göran Eriksson, posing as a businessman interested in opening a sports academy. Eriksson, however, asked him to take over Aston Villa FC, and revealed that he intended to leave England after the World Cup to become Aston Villa manager, and that he would approach David Beckham from Real Madrid to become captain. On 23 January, the Football Association announced that Eriksson would leave his job after the 2006 FIFA World Cup, and it was thought that the News of the World allegations played a part in this decision. This was later denied by both parties, with Eriksson explaining that there was a prior arrangement to terminate his contract immediately after the World Cup. In 2016 Eriksson was reported to be suing Mahmood for having cost him his job.

In September 2004, he posed as a Muslim extremist to "expose" three men who were trying to buy radioactive material for a suspected Muslim terrorist group seeking to carry out attacks in the United Kingdom. However, the men were later found not guilty following a trial at the Old Bailey, with the judge criticising the News of the World for not checking the credibility of the story.

In 2004, Mahmood led an investigation into exposing the creation of a dirty bomb, through the supply of the fictitious substance red mercury, to three men from a supposed terrorist group. Mahmood was registered as an informant for the Metropolitan Police Anti-Terrorist Branch during the story, which led to a criminal case prosecution by the Crown Prosecution Service. The case, signed off by the Attorney General, collapsed in July 2006.

In 2003, Mahmood was responsible for reporting an alleged plot to kidnap Victoria Beckham to the police. The subsequent trial collapsed after it emerged that Mahmood's main informant, Florim Gashi, had been paid £10,000 and could not be considered a reliable witness, and was later deported from the UK. Judge Simon Smith referred the News of the World' s role in the affair to the Attorney General. One of the men involved later sued the News of the World for libel and won. The paper issued an apology and paid libel costs.

Mahmood's targets include various society figures, including Sophie, Countess of Wessex, in 2001, Princess Michael of Kent in 2005, and Sarah, Duchess of York, in 2010.

Mahmood won the "Reporter of the Year" award in 1999 for his exposé of Newcastle United bosses Freddy Shepherd and Douglas Hall, who mocked fans and branded Geordie women "dogs" after taking Mahmood, posing as the sheikh, to a brothel in Marbella.

In 1999, after a Mahmood investigation exposed the Earl of Hardwicke and another man as drug dealers, the jury sent a note to the judge explaining that they had reached their decision to convict the two men with great reluctance. They said that they would have acquitted the defendants if the law had enabled them to take into account Mahmood's "extreme provocation" of them to sell him cocaine. The judge agreed and passed suspended sentences.

Mahmood has won various newspaper awards, including British Press Awards "Reporter of the Year" 1999 for his exposé of Newcastle United directors. At the awards ceremony, a figure dressed as a sheikh collected the award, and then revealed himself to be Kelvin Mackenzie, former editor of The Sun.

Mahmood then worked for the Sunday Times, which he joined in 1989. A managing editor at that time, Roy Greenslade, later alleged that Mahmood was dismissed for trying to cover up a mistake. Mahmood has consistently disputed Greenslade's version of events. Mahmood then briefly worked as a producer on David Frost's TV-am programme, before joining the News of the World in 1991.

Mahmood first gained employment as a journalist at the age of 18, exposing family friends who sold pirate videos. This gained him two weeks' work at the News of the World, after which he started freelancing at the Sunday People. In 1984, while trying with fellow journalist Roger Insall to expose a vice-ring at the Metropole Hotel at the National Exhibition Centre, Birmingham, according to Mahmood, he first used the sheikh disguise when inviting prostitutes to a hotel room.

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.

Mazher Mahmood was born in Small Heath, Birmingham, on 22 March 1963, the second of two sons of Sultan and Shamim Mahmood, journalists from Pakistan who had come to Britain three years earlier.
