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.
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.
