"Nick, you're a risk to our security"

And so it came to pass.

As I predicted yesterday, Brown didn't play Mr Nice Guy with Nick Clegg.

"Nick, you're a risk to our security," said Brown. That's pretty rude. Absurd, too, but it might resonate with some.

The really interesting thing is the contrast between Brown's attack on Clegg, and Mandelson's impassioned defence of Clegg.

Keep watching for Mandelson's post-election coup. It's coming, and Brown knows it. And he's not going to go quietly.
