There is little doubt, as Matthew d’Ancona and others have pointed out, that Gordon Brown is secure in the thought that he has established himself as what is called these days a ‘change agent’, cutting the ground out from Tory cries that ‘It’s time for a change.’ If you want change, go for the experienced clunking fist rather that the PR tyro.Unfortunately, not all change is in Britain’s interest. Which brings me to the by now, or at any rate soon to be, forgotten visit of the Prime Minister to President Bush’s retreat at Camp David. You know — the visit that the press hailed as a triumph for Brown because he (a) forced the ever-courteous George Bush to forswear his cowboy boots and open-necked shirt in favour of a jacket and tie, (b) described the discussions as ‘full and frank’, the unpleasant diplomatic term usually reserved for meetings with such as Bashar al-Assad, and (c) generated headlines from the right (‘End of the affair’, Daily Mail), left (‘Brown fails to praise Bush at summit’, Guardian, front page) and centre (‘Mr Brown noticeably failed to return such compliments’, the Times) that represent PR coups of the sort that have made David Cameron what he is today.
