You hold political power in trust, at least in a democracy. You are supposed to use it to advance the interests of the electorate while you have it and then pass it on in the best condition possible to the next incumbent. That is unless you are Gordon Brown, who is cynically using what will probably be his last days in power to shore up the Labour party and lay traps for any incoming Conservative government. That he is wrecking the economy so that it will take a generation to fix seems to interest him not. That the media almost to a man have seen through his grinning façade doesn't seem to bother him either. At least the answer to the future pub quiz question 'who was Britain's worst Prime Minister' is clear.
It seems that Alastair Darling tried at least to start addressing Britain's crippling budget deficit, but Brown and his acolyte Balls put him back into his box. Maybe he's going for 'who was Britain's worst Chancellor?'.
