The implication seems to be that Brown was still pushing to have Balls installed as Chancellor on Friday morning. Given how a promotion for Balls could have sparked a Cabinet revolt, this was clumsy politics even before James Purnell's resignation on Thursday evening. But trying to push it through after is just deeply, deeply stupid. In the end, one of the grand ironies of the reshuffle is that Darling, by fighting against Brown, actually saved the PM from himself.“
"Early on Thursday evening, Mr Brown attempted to bully Mr Darling into leaving the Treasury. Then and again on Friday morning, Alistair Darling pushed back and the prime minister was finally forced to abandon the idea of installing Ed Balls at Number 11."
