All that being said, I do not pretend that the choice - whether October, November, next spring or beyond - will be easily made. Despite all the discussion at last week's Cabinet - itself a sign of change in style since the days of Blair's sofa government - only Gordon Brown himself can make the fateful decision. And, if he gets it wrong, the penalties will be monumental. The Labour party would hold him solely responsible for the end of its longest term in government. The obsessive Blairites, who still hide in the political undergrowth, would come out into the open and gleefully proclaim their own version of events. Tony, they would say, was a born winner and Gordon is a natural loser.
