I quite like Keir Starmer and I don't think his performace so far has been quite as bad as some want us to believe, but I am mystified at his decision to support Mandelson.
To my mind, Mandelson has always had an air of dodginess around him, so I was surprised when he got this appointment in the first place, but why would the PM risk his own career and other political fallout, rather than saying "sorry Peter, you're going to have to go, I can't defend this"?
