Worth having a squizz at the Labour Files. One needs to be a bit cautious as it's certainly an emotive Al-Jazeera hatchet job, but there's a lot of evidence in there as to why the Labour Party has been so ineffective.
In the middle of a cost of living crisis and a structural transformation provoked by Brexit and hurting a lot of people, a touch of pedestrian, old school social democracy like the 2019 Labour manifesto would probably please the banks as much as anyone.
Trouble is Starmer's now created a version of Labour incapable of ambition or mobilising support.
