The London mayor faces a grilling on Sunday over allegations made against him in an upcoming BBC documentary. Eddie Mair, interviewing Boris Johnson on BBC1's Andrew Marr Show, confronts him about claims he made up quotes while working for The Times, lied to his party leader about having an affair and provided a friend with the address of someone they wanted to 'beat up'. Mair also asks Johnson about his refusal to discuss whether he wants to be the prime minister, to which he replies 'I don't want to talk about this'
