Peter Mandelson has just given a highly entertaining, if unrevealing, interview with Andrew Marr. He stonewalled for most of the interview, but the one thing Mandelson unwittingly gave away was that Brown did indeed want Balls to be Chancellor. Paul Waugh has just twittered that his use of the words "surprised and disappointed" by Purnell's resignation were exactly the same ones which were used in the leaked Labour memo to MPs.
Mandelson also accused Caroline Flint of lying. He said she could have attended Cabinet every week if she had wanted to. She says she was only invited once. They can't both be right. Perhaps she'd like to accuse Peter Mandelson what he has accused her of.
At the end of the interview Mandelson said the only thing which would bring Brown down would be if someone stood against him. It was an open invitation. Will anyone take it up?
