Sadiq Khan has attempted to distance himself from extremists with whom he has been associated.
Labour's London mayoral candidate said despite having shared platforms with alleged radical clerics, he was the only candidate fit to tackle the surge of Islamist extremism in Britain.
Mr Khan said “unsavoury” figures including Louis Farrakhan, the controversial American head of the Nation of Islam, were “not my chums”.
In 2002 Mr Khan - who was a leading human rights lawyer before he became a politician - defended Farrakhan as he battled to overturn a government ban on him entering the country.
