Don't see it. Labour Party works to its own drummer here. Longer term allows Corbyn supporters to deselect those who don't support him. They also were worried by Chilcott. Also having a Tory party about at that stage to tear itself apart isn't worrying. Possibly because they thought there would be an internal battle in the Tories, they thought there was a chance for some knifing. As usual they forget about the Tories will to power.
If I've got this right they can only deselect if there is a GE about to take place, hence my argument.
Chilcot? Can't see this really. Unless they had a quick fire process to get Corbyn out, which the half cocked twats didn't have, then I can't see the link here.
But the Tories weren't about to have an internal battle because Cameron stepped down; the only real possible cause of an internecine, if he had stayed. What his stepping down did do was bring in a new PM which had the threat of a early GE, hence the deselection angst.
And finally, on Ch4 News last night, a Labourite said that this had all come about because of the possibility of an early GE.
