It was kind of the Tory party conference organisers to bring on the entertainment half way through the political speeches. As Quentin Letts comments in the Mail, a Benny Hill set always goes down well with the Tory punters - and no one does Benny Hill as well as Boris Johnson. A serial adulterer who can't keep his trousers on, Boris would also be a natural for a Brian Rix farce - but perhaps he's saving that for next year, when he hopes to be leader of a Tory party in exile from government.
For full effect he should perhaps have arrived on stage via a zip wire down the length of the auditorium, over the heads of the few dozen surviving Tory party members clustered in the front seats. Dressed in Spandex shorts and a sequined Union flag wes'cot with a rubber chicken. But still, he was good enough as he was to entertain the serious politicians there.
