If you add up the polling numbers for Lab+LD+Green+SNP+Plaid+SDLP I thinks it's over 60% in the UK expressing voting intention for a centre/left-of-centre party, which suggests a more left-wing electorate than most European countries.
But I suppose you have to factor in how much of that is just 'anyone but the useless Tories'.
And what 'Left' even means in the UK, with the Overton window having shifted so far to the Right since Thatcher.
And then there is the constant threat of rightwing populism which will haunt Western democracies for years to come, even if Trump is dispatched.
The appeal of the brownshirts to bewildered voters in troubled times isn't going to go away.
