This is a co-ordinated attack, Benn and his cohorts have been waiting for the opportunity to do this. Labour needs cleansing of the likes of him who want to be a Tory Lite who actually don't appeal to anyone , if you want Tory you vote Tory as proved last year.
Corbyn has to up his game now, you're right he has to listen to the concerns of everyone who has voted Labour but now votes UKIP, for too long traditional Labour voters haven't been listened to , from Brighton to Newcastle and now the Labour Party has to reflect this and not be a party that encourages the London elite to run rough shod over the whole country.
I take it when you write in lower case, you are trying to make a serious point. What exactly is Corbyn's game ? His political thinking is unchanged in 40 years, how and why is he going to re-invent himself now ? his brand of woolly socialism is international and inclusive of the repressed everywhere, even if some of those repressed are rather closely linked with those prepared to use violence and terror to further their political ends. It would be truely enlightening to see the world through those eyes, but much like owning an all purpose amphibious flying car, I would rather have something entirely more practical right now.
