Based on Labours 40% vote share in 2017 they would have had 260 seats rather than the 262 they got, so not much difference. However the Conservatives vote share was 42.3% which would have given them 275 seats rather than the 317 they got.Fair point. Would they have won or gained many more seats with PR. Probably not, right?
Of course that is just a straight percentage share of 650 seats. There are many different types of PR.
