We really need electoral reform. Whilst I'm happy for the Labour Party, it really isn't healthy for them to get 500 seats with 47% of the vote, especially when they are simply benefitting from the "anything but Tory" votes, rather than having an overwhelmingly popular programme of their own.
If Starmer got in with a massive majority like this, then it's really setting the country up for a massive crisis a few years down then line, when everyone gets disillusioned with Labour, and has literally no safe place to move their vote... It would present a dangerous opportunity for fringe crazies to play the populist card, and send us all straight to Hell.
PR would give fair influence to sensible centrist voices which are currently being stifled.
