It's not hard to identify the political winners of the Olympics. Boris Johnson, who never missed an opportunity to make a populist intervention, and whose named was chanted by thousands during that extraordinary speech in Hyde Park, is now spoken of as a potential prime minister by both the left and the right, and is increasingly viewed as a threat by Labour.

Beginning with the Queen's skit with James Bond (the highlight of the Olympics ceremony for voters, according to polling by YouGov), the royal family has seemed more at ease with itself than for decades. The BBC's coverage has reminded us of the virtues of public broadcasting, whilst the armed forces, filling the void left by G4S, have renewed their bond with the public.

But who are the losers? Tory MP Aidan Burley's curt dismissal of Danny Boyle's ceremony as "leftie multi-cultural crap" did little for his career prospects, and with a slim-ish majority of 3,195 in Cannock Chase, a seat that Labour held from 1997-2010, he is unlikely to be returned at the next election. Mitt Romney's suggestion that the UK was unprepared for the Olympics, inaccurate as it turned out, damaged his reputation at home and abroad, with Boris openly mocking a supposed ideological ally ("There's a guy called Mitt Romney who wants to know whether we're ready"), David Cameron quipping that it's easy to run an Olympics in "the middle of nowhere" (a reference to Romney's management of the 2002 Salt Lake City Winter Games), and Carl Lewis concluding that "some Americans just shouldn't leave the country".

The biggest loser, however, is the current occupant of 10 Downing Street. Rather than enhancing Cameron's reputation, as some Tories hoped, the Olympics have diminished it. The cringemaking photo posted by the No 10 Twitter feed of the PM watching the boxing at home while wearing a Team GB polo shirt looked like what it was: a desperate final attempt to reap some political benefit from the Games. Rather than serving as the proud leader of a successful nation, Cameron has spent more time fending off criticism of the government's school sports policies and dismissing fears that the Olympics have reduced economic activity. As Prime Minister and the leader of a party that won just 36 per cent of the vote at the last election, Cameron was never likely to survive the Games unscathed. But what makes the negative press coverage even more galling is the adoration for the prince across the Thames - Boris. While the crowds cheer for Boris, they boo for Cameron. For the first time since he became Prime Minister, conservative commentators are asking how long he can continue. After two weeks in which Britain has rarely seemed happier, few could have imagined a less happy end to the Games for Cameron.
