Genuine question.
How strong do you think the influence and thoughts of Momentum will be when the manifesto pops up?
Why do people keep going on about Momentum? Its numbers were small. At its peak, it was an organisation that represented about 10% of Labour members - I believe that it's currently about 8%.
There is a sister organisation in parliament, the Socialist Campaign Group, that has strong links with Momentum but this is made up of 35 (out of 202) Labour MPs - about 17%. With those numbers, I can't see there being too much influence.
