Did John Prescott really mean what he said?

Oh dear.  Relishing his return to the Today programme, John Prescott rather over did it with his criticisms of Charles Clarke:

and Charles, if you’re ashamed to stay in the party it’s obvious what you should do. I’m really staggered.

Having thought about this for a second longer than John Prescott, I am none too sure whether Brown would ideally want an MP to resign the party whip at the present time.

Hardly a wise thing for the former deputy prime minister to have said.
