Has Gordon Brown outstayed his welcome at 10 Downing St?

I think Mr Brown was truly in his element within the ministerial role of C of the E, and the 'economy' is the only issue I think he discusses with any comfort, but I think his ego has led him to ume a position he clearly does not have the panache or people skills to enact, he clearly looks out of his depth around people, and he also lacks the political diversity needed to discuss broad political issues in a persuasive manner. he clearly looks like Frank Bruno after having had 2 unsuccessful attempts at beating Mike Tyson, and I think he should have the good grace to resign, which I think he will do in the next week or so.....
