It never seems to be talked about but I think it's pretty clear that Starmer/Labour have very deliberately (and successfully) positioned themselves as being centre-left and moderate because they know it's the way to win an election. Whilst people are sick of the Tories, I think a lot of their ideology is still fairly popular, and left-wing people like myself need to learn to live with that. For example, I think it'd be hard to get elected without saying you're going to clamp down on small boats, or without promising to keep us out of the EU. I suspect Starmer and the others are perhaps more left-wing at heart than they've positioned themselves. But having campaigned and almost certainly won on this basis, it's hard to see how they could implement more left-wing policies. Although some of the stuff in the manifesto is appealing, like the GB Energy company.
