Surely a more left approach isn’t going to solve either of these issues and will just cause Labour to be even less popular than they are now. Or have I got it all wrong?
Well, it wasn't long back a "more left" version of Labour tallied more votes in two General Elections than Starmer's iteration did in 2024. They may not have ended up in Government, but it's clear that version of the party was attracting votes "for" something rather than just as a means to remove the Tory Government.
Starmer's Labour won a loveless landslide, their approval cratered within a year and is showing no signs of recovery. Clearly the stupidity of trying to out-Reform Reform is getting them nowhere, so it's difficult to conceive of them making any change that could accelerate that unpopularity. It's clear as day absolutely nobody likes this version of Labour, IMO that's because they don't actually stand for anything or anyone. They've tried to be all things, and that's just resulted in everyone hating them because if you want Right, the Tories are better, if you want Far Right, Reform is the original, if you want Left, The Greens have stolen that platform.
Labour in England is going through the same thing that has killed Labour in Scotland over the past 27 years. They went off chasing a Centrist vote, but abandoned their ethos and convictions to do it. They've nothing to fall back on because the party deliberately run anyone with convictions out of the organisation, and now their old stomping ground has been taken over by a newcomer.
