Mazher Mahmood’s chances of resurrecting his undercover journalism career were dealt a further blow with the release of his police custody photo last night.

Mahmood has always previously fought hard to protect his identity claiming that publication of his photo would put himself and his family in danger. His journalism has previously led him to expose gangsters and criminals.

In November 2014 he failed to get an injunction against the BBC stopping it publishing grainy undercover footage of him driving.
