I have no idea what there is to like about him. He's so obviously a careerist who's plotted a course to the leader's job. He shamelessly stuck the knife into Corbyn's back in a coup after agreeing to be part of Corbyn's shadow cabinet team, and then when his coup failed, accepted another offer to be in the shadow cabinet.
His 'taking the knee' the other day was a huge insult to the people seeking justice for Jean Charles Menezes...someone he allowed the Met to shoot dead without punishment. What an unspeakable hypocrite he is.
One decision in many he took whilst head of the CPS, and a decision based on insufficient evidence I believe.
Any figure in that role will have individual decisions that can be picked apart. There is also a large body of work that can be praised.
I understand the criticism about that decision but I don't think it should preclude him from being leader of the Labour Party now, and possibly an effective one.
