Just for the record, Tories have made noises that they're taking a massive step towards proposals set out by Corbyn and McDonnell because they were extremely popular policies and this should be evidence enough that leftwing politics isn't dead. (We haven't seen whether these are implemented properly yet and not doubt it's Labour's fault if it's not implemented well).

They've combined that with a creeping authoritarian, regressive culture which attacks opposition in any form in a way that would make Trump or Orban (Hungary) proud.

I had a conversation yesterday with a conservative voter (small c) who said they'd never vote Tory again because of what they're currently doing economically and culturally. We're not hearing that yet because i) how popular this political position is (economically centre-left, culturally right, authoritarian) and ii) Tories are still a party friendly to billionaire's.
