You missed how they're also threatening to field a different candidate in Harriet Harman's seat if she runs for speaker, solely because she's not Momentum.
They'd literally rather have a Tory as speaker than a very well respected centre-left Labour candidate.
Where do I mention the speaker in my post?
Also listing to LBC this am Momentum is a large influence on tactics they are scared Corbyn will retire aged 70 and Watson would take over they had the vote at the NEC 17 v 10 to scrap the deputy leaders post not enough of a majority so they now want two deputy leaders ......
they lost the vote on Clause 4 for nationalisation etc that Blair altered this am .....
They are the real reason they will never get into power until they move on to centre ground..... as I a Labour voter will never vote for a left wing marxist party within a party oh and by the way I don't like Tom Watson as an MP for numerous reasons.....
