British politician Elected as the first Muslim mayor of London, a Western capital city, Sadiq Khan won with more than 1.3 million votes, in what was called the biggest mandate in the history of British politics. And the Labour candidate managed his landslide, in 2016, even after his opponent smeared him as a 'radical' and shamelessly accused him of giving 'oxygen' to extremists. A former human rights solicitor and chairman of the pressure group Liberty, Sadiq Khan was elected as MP for London's Tooting area in 2005. He was shadow justice secretary and shadow minister for London. The son of a bus driver, Sadiq Khan grew up on a council estate in Earlsfield, south London.
