UPDATE 20:05 A few more emails have now been leaked to leaked to LabourList, who have also reproduced our first batch.
UPDATE 23:50 Amazing to see some of these on Newsnight of all places!
The following email appeared on LobbyDog at 16:24:
I can only imagine you have taken leave of your senses. God knows what harm you have caused with your indulgence. I am sure your view is not shared by the majority of the PLP or ordinary party members who you arrogantly assume should have no say in this process. I am sure there will be no appetite for your proposed distraction and it will disappear as quickly as your credibility.
A whole bunch more of that thread has now been leaked to Scrapbook:
In my opinion the forming of a circular firing squad is never a good idea. You don’t just shoot yourself in the foot you wound the Party – and,more importantly, those who depend on Labour.
Steve Pound MP
I share your anger and frustration at the indulgence of our two colleagues and the distraction that it has caused. Whatever their motivation it is difficult to believe that they had the interests of the Labour Party uppermost in their minds. Now that we are into the New Year we should be fighting the Tories and not ourselves.
I do not always agree with John Heppell. But I, also, can only assume that you have taken leave of your senses.
As someone who has known and worked closely with you both for over two decades, I am more disappointed than I can say by this unwise and totally uncalled for e-mail. I am also at a loss to know how people of your obvious intelligence, experience and achievement could possibly view it as helpful.
It fuels the speculation and uncertainty you purport to want to end and, worst of all, it betrays the very causes you have spent your lives fighting for. I do not know what led you to do this but I do know that in sending this e-mail you have lost my respect.
We have been promised more by our source. Follow @psbook for updates.
