Jon Lansman and his allies in Momentum have through extraordinary means overturned the decisions of the last Momentum national committee i.e. to hold a delegate based Conference to set rules and determine policy. They have also determined that expelled Labour Party members cannot be members of Momentum, it’s claimed that this is in order to prepare for affiliation as a Socialist Society. At least some of the Socialist Societies have non members as do the Trade Unions, it’s part of their design goals. As Jill Mountford points out in her blog, in the ’80s, the Left opposed expulsions despite stronger provocation. This is a power play by the same people that have been losing to Labour’s right since 1980, the goal should be to energise new joiners and those that have rebooted themselves; playing the same old games lets them down and will lead to Labour’s destruction.
