Game on: Boris has accepted Pippa Middleton’s ‘Whiff-Whaff’ challenge. The Mayor of London has declared:

‘I’m game if she is. Happy for Pippa to join me on a visit and see the benefits of our £22m Sports Legacy Fund in action.’

While Pippa would no doubt enjoy that, the Spectator is happy to set up a ping pong table in our garden. Pol Roger will be served.

UPDATE: Mr Steerpike has confirmation Pippa is still up for the contest. I hear she ‘sensed some nerves’ in Boris’s reply.
