I don't see why there should be an election. We all vote for local MPs to represent us - and the sum of those MPs decides the governing party, which in turn decides who will lead them. A change of leader does not alter that flow of responsibility.
That said, we all know that, on the whole, we vote with party allegiance. This puts me in a quandary - I have always voted Labour, and my last MP (Jo Cox RIP) was superb. I voted for her, not Ed Miliband, who I thought would be an ineffective leader. At the time, I was glad I had such a strong local candidate to give my vote to, and I hope that remains the case when her successor is chosen.
Corbyn is something else though. I really cannot support the party with him as 'leader'. I put that in quotes, because I don't believe him to be a leader. He is far better suited to heckling the government - and opposition - from the back benches. Leaders cannot be mavericks as well.
I suppose I'm a Blairite at heart. Putting to one side the disastrous Iraq war decisions, I thought he had a good premiership, with money spent on the things I thought were important: the 'third way' in politics. I would like to see Labour back in that kind of mode - realistic socialism - but without the endless spinning of stories that somewhat took over. Andy Burnham as leader would, I think, make my choice easy, given that Alan Johnson has repeatedly ruled himself out.
