The one's to watch are Momentum. The party within the party practicing the same 'entryism' as Militant of old.

One key passage entitled "Consider for membership people rejected by Labour" states:
"It has been pointed out that the Labour Party may unreasonably proscribe organisations or exclude individuals from membership. For this reason, it is proposed that the National Committee may decide by resolution to admit to membership any person whom it feels has been unfairly excluded from membership of the Labour Party, and shall be the final arbiter in any dispute about whether an organisation is 'opposed to the Labour Party' as a determinant of membership of Momentum."
Still at £10 a pop it could cause more disruption within the Labour Party than the £3s I invested in 'Corbyn'!
