The cock-up of a tweet from his spokeswoman: " ''Hypocrisy of Cameron pimping himself out in Zurich..." is precisely the kind of silly unforced error that lucky politicians do not succumb to.
Of course, if in a few minutes, England were to win then Cameron looks like a very lucky politician indeed, while Miliband looks, well, like a loser.
UPDATE: well. I suppose, predictably, England did not get the World Cup, but even that may be lucky, if the FIFA corruption scandal gains any further traction. After all awarding the world cup host nation status to a genuine Kleptocracy does kind of give the game away.
