You mean the same rules now being employed by the Labour Party to ensure some 'members' can't vote for Corbyn in the upcoming election ?
I mean: was anything to do with Corbyn's election as leader in contravention of The Labour Party's Rules governing the election of a leader.
If not there are no grounds for complaint. The fact he is perceived by some to be incompetent is irrelevant,added to which as he has never held a ministerial post on which a sound judgement could be based in that respect. Making a judgement on his competence or lack thereof is based merely on bias or personal prejudice.
If people don't like Labour's policies under Corbyn they can always vote Tory, LibDem etc or not at all.
The idea that "the Labour Party is now dark pink rather than pale blue and I don't like it so Corbyn is a toss pot" is bit of a laugh.
Signed a life long believer in benevolent socialism who has always voted Tory. Now figure that out.
