Representative of the proportion of all of the vote. No obviously not. Representative of the wishes of 660 or so sets of local people ? Yes, absolutely.Understand that, and maybe they'll be a way of accommodating this, not with strict PR, but that'll be a part of the debate I'm sure. That said, Labour are predicted to win 39.7% of the votes cast, which will see them with around 72% of the seats in Parliament, representative?
Personally I think the latter is better. In theory working class people get a representative who understands their needs, “woke” places like Brighton Pavilion or Hove & Portslade get a rep who “gets” them and, frankly, so might Clacton’s racists.
I like that system, you prefer PR and that’s fine. We’ve both got good reasons why I think.
