Dan Hodges on the news last night was saying supporters of Corbyn's team are physically blocking other Labour MP's from going into his office and talking to him in they persuade him to stand down.
I don't know how true that is (Dan Hodges is from the Daily Mail) but IMO it's not to late to save Labour party from extinction but unless one of the heavy hitters in the party stands up and takes charge and sorts this mess out, bans momentum and brings the party back to the centre ASAP Labour as a party will cease to exist as we know it.
On the other hand if Corbyn wants to bring the PLP more inline with Labour 'supporters' he should replace the 170 odd MP's who voted against him and replace them with the Trots, Marxists and other anti semitic bigots who have latched onto the party since he took over. I don't think Corbyn is a bad person and I don't think he's anti semitic but I do think he attracts the wrong crowd.
