McGrath makes a crucial point: Corbyn will be arguing for his policies within a Labour Party that is much more democratic than it has been in years. He is disposed to listen, more so than any leading politician in recent times. He has not delivered a Burnham-style top-down "manifesto," he has floated options.

A large part of his appeal to Labour's constituency parties is that it is not in his nature to impose faceless candidates whose only credentials are that they are on-message. It cannot be wondered that New Labour's elite, and their paid apparatchiks, are alarmed by the winds of change now blowing.

[Diversion: Akenaton claims there is right on both sides on the Palestine-Israel question. Even if there is, it is not equally distributed. These maps show the extent to which parity is reflected on the ground.]
