Contempt for Corbyn is rivalled only by disdain for the party that elected him. His critics argue that the membership is unrepresentative of the country as a whole. By definition most political memberships are, but that does not mean they represent nothing. In this case the Labour party membership represents two quite crucial constituencies. First, the group that will help select the Labour MPs and leaders. And second, the group that will knock on doors and staff the phones to fight for a Labour government. Those are no small things.

If Corbyn resigned tomorrow, the issues that he raised would still stand, and the Parliamentary Labour party would still have no coherent response to them. He did not create the dislocation between the PLP and the membership, he merely illustrates it. His critics say they want their party back. Their party may well say it wants Corbyn back. In the absence of any reckoning as to how that discrepancy came about and any idea what to do about it, his critics are going to destroy the party they claim they love to save it from a leader it prefers.

Corbyn’s critics are hellbent on destroying the party they claim to love
