A third of its MPs could be under threat of deselection if Ken Livingston and Ken Loach have their war. They are calling on members of Momentum, Left Unity and any old Tom, Leon or Karl to challenge any MP who voted for the bombing in Syria.
They have also turned to the now compulsory use of Farcebook and Twatter to insult and threaten anyone who disagrees with them.
Maybe it is time for the 66 "targets" to grow a communal backbone and walk away and form a new party.
There would be some big-hitters in the new group and even some of those who voted against the bombing would join them.
