Among the celebrities to catch a glimpse of at Wimbledon yesterday were David Cameron, Boris Johnson and Alex Salmond.

Sat in the Royal Box, SNP leader Salmond didn't quite make it to the first row, where Pippa Middleton and the Duchess of Cambridge sat.

Meanwhile, the PM claimed that the pressure on Andy Murray was worse than being in government.

Cameron's searing tennis commentary went as follows: "The thing about singles tennis is that there's no-one else out there. It's just you.

"And the pressure on the individual single person is immense.

"In doubles you share it, in government you have a cabinet, you have a team."

In other politician-spotting news, justice secretary Ken Clarke and culture secretary Jeremy Hunt were spied with Hugh Grant and Gordon Ramsay at the Grand Prix. (You can see photos of Ken Clarke schmoozing here.)

Good to see that the cabinet are taking this week's crucial House of Lords vote in their stride.

It's not like Nick Clegg describing tomorrow's vote as a "test of the prime minister's leadership" is anything to keep you cooped up at the weekend.

As Cameron might say (or not), 'Chillax.'
