There are a couple of big differences though. Firstly, there's no-one who could be called far left in the ranks of the shadow cabinet, so they're a long way from the sphere of influence. That's in sharp contrast to the Tories, who have promoted the likes of Braverman to the front bench and where 30p Lee is a vice-chairman.Agree, the extremes on both sides are dangerous however this current period is the first that I can recall of the far right of the conservatives dominating the party as much as this. It'll come home to roost at the next election. Problem for Labour will be if the far left then try to undermine Starmer's government from day 1 with unrealistic demands.
Secondly, the Labour party has centralised selection of candidates and has over-ruled many who have been too centrist. Again, this is in sharp contrast to the Tories who expelled many of their more moderate MPs. Politicians like Grieve, Gauke and Stewart would probably be an asset in attracting the middle ground but they're in the wilderness.
There is one area of uncertainty and that's the potential large swing to Labour. That could mean a lot of candidates who weren't expected to win becoming MPs. That's how we've ended up with the likes of 30p Lee, Gullis, Bradley, Clarke-Smith, Benton and others. There may well be a few oddballs who end up as Labour MPs but I'm not there'd be enough to make a difference.
