Boris Johnson: I've not decided whether to stand as an MP Mr Johnson appeared flustered and after avoiding five questions from the caller, who gave his name as Tony in Woodford, said: "Let me explain that I've got a big, big job to do and I've just got to focus on that. The more I go on about the subject that you kindly raise, the more people will babble on about it. Tony will you forgive me if I just say I understand why people are interested. I would like to have a career either as a romantic novelist or a tight-end prop for England. These things are unlikely to happen. Because the honest truth is I don't know. I don't know and I've got to get on with being Mayor of London. Mr Cameron has previously said that he would give Mr Johnson a "warm welcome" if he returned to Westminster politics. "My message to him is that... it would be great to have you back in the House of Commons at some stage contributing to public life," Mr Cameron said.
