There's nobody out there, irrespective of political Party, that inspires me with any confidence. The term ' doom loop ' springs to mind.
Labour are currently in the process of blowing the huge mandate they were awarded. I'm sure a lot of us in the course of our careers have taken jobs on where the previous incumbent made a mess. But in my experience, whilst acknowledging that initially is fine, to keep referring back to it isn't. The job's yours now, it's what you wanted so own it and get on with it. Be judged on what you do. It's not working out at all well at the moment.
