Boris Mania is in full flow today as a YouGov/Sun poll finds that the Tories would close Labour’s lead to just 1% if the London Mayor replaced Dave as leader. Cameron versus Miliband sees Labour take a six point lead, but if Boris were in charge Ed’s rating would fall and the Tories’ popularity would rocket up. No wonder Dave was so testy yesterday…

But could it all be the work of his sinister backer? The Mayor is hardly making hard work for conspiracy theorists. BoJo invited Uncle Rupe to the Olympic swimming finals and two days later he receives a very favourable poll in the Sun:

London in best shape ever. All overboard about the Olympics, brilliantly organized by Zeb Coe and Boris Johnson.
