I caught the end of that earlier. This bit disappointed me:
Interviewer: - If you lose, will you resign as leader?
JC: - I won't lose
Interviewer: - But if you do, will you stand down as leader?
JC: - I'm planning to win.
Interviewer: - But what if you don't?
JC: - I'm planning to win.
Would it be so hard for him to say he hadn't made up his mind yet? I thought Corbyn was above 'not answering questions'.
