Peter may well be right to argue that it's hard to see how Gordon Brown can sack Harriet Harman. But let's just say that she's not really helping the government these days. Take her performance this morning, for example:
"Sir Fred Goodwin should not count on being £650,000 a year better off because it is not going to happen," she told BBC One's Andrew Marr show...And it might be enforceable in a court of law, this contract, but it is not enforceable in the court of public opinion and that is where the government steps in."
UPDATE: Jeff Randall's column today is splendid and therefore highly recommended.
