Legendary BBC Radio presenter and 'Professor of Pop' Paul Gambaccini was shunned by friends and organisations he had supported, including the Labour Party, after he was arrested over false child sex allegations by officers from the Metropolitan Police’s controversial Operation Yewtree. He was even taken off air for a year by the BBC. As he secures a £250,000 payout from the Met for breaching his privacy by allowing him to be identified, he tells award-winning crime writer Stephen Wright about his seven-year battle for justice - and the “catastrophic” effects of the bogus accusations against him.
