Unlike Tony Blair, he comes from a working class background - his siblings would still call themselves working class.
As a very bright lawyer, he could have sought a path which made him rich quickly but instead chose human rights which isn’t an easy route to take and he’s defended ‘the little guy’ against corporations. He’s also anti-death penalty.
Ok, he’s a Sir, and I’ve heard people (perhaps not unreasonably) question why the leader of the Labour Party would have a title like that. But he earned it through work for the criminal justice system.
On the face of it, it seems as though he deserves a chance.
I would much rather have him as PM than a former Bullingdon club member who used to burn money in front of homeless people for the fun of it.
