According to James Forsyth:
Khalid Mahmood has resigned from the Labour front bench saying that 'A London-based bourgeoisie, with the support of brigades of woke social media warriors, has effectively captured the party' source
This comes after the historic election loss for Labour in local elections, where the party bled even more in working-class areas than it did in 2019.
That makes sense. What is often not understood, is that the top brass in an organization is far more interested in its position within the organization, than it is in the success of the organization. It makes sense that a faction opposed to Corbyn would try to undermine his prospects, if that would ensure a Labour loss and thereby a victory for them within the party.
I mean, the moment Corbyn confirmed that he would consider putting Tony Blair on trial for war-crimes, or at least having an inquest or something, his fate was pretty permenantly sealed. It was very much the Blairites that were at the heart of the Labour push to ensure that Labour under Corbyn lost at any cost.
True, but it's not like Momentum, Corbyn's base, were lily-white themselves. This is two thoroughly unpleasant groups tearing what's left of the Labour party into pieces so they can claim primacy over the carcass.
