Despite the Labour party winning an unprecedented majority of 174 - the largest any party in the UK has achieved since 1832 the party’s share of the vote only increased by 1.7% to 33.8%; hardly a winning endorsement. Turnout was approximately 60% which is the lowest since 2001. The LibDems who have regularly campaigned for PR may now be changing their tune. Due to the nature of how the party’s support is clustered in particular geographical areas the LibDems they have disproportionately from FPTP. The LibDems polled 3,499,933 or 12.2% of vote and received 71. Reform UK in contrast has it support thinnly spread across the UK. The party polled 4,091,549 or 14.3% but on won four seats.
Oppositions don’t win elections, governments just lose them.
I don’t think that’s always true, but it’s true in this case.
