Has any vote ever been won by a majority of the entire population, eligible to vote or not? If that’s the standard you’re after nothing would ever pass and no government would ever be formed. Seems an unreasonable bar to set, to me.
Not in the UK, indeed the largest voter turnout of any election/referendum in the UK was...the EU referendum. Making it the largest vote for a decision in the entire history of the UK.
So best described currently as `interesting times`.
