Harman hails her 'Superman' Brown

Gordon Brown claims to be saving the world

Gordon Brown has been called "Superman" in Parliament as the fallout from the prime minister's inadvertent claim to have "saved the world" continues.

The Tories have been mocking Mr Brown after his slip of the tongue over the economy at Prime Minister's Questions.

Mr Brown had meant to say he had "led the world" in rescuing the banks.

But Commons leader Harriet Harman told Tory MPs that she would "rather have Superman as our leader than their leader who is The Joker".
