Victoria BeckhamVictoria and David Beckham are well-known to have Hollywood A-list friends - Tom Cruise & Katie Holmes for example - but it seems like they have political A-list friends too: the couple have been invited for a weekend break with British Prime Minister Gordon Brown and his wife Sarah at Chequers.

Chequers Court in Buckinghamshire is the official country residence of the PM and has been used as a country retreat since the 16th century estate was signed over to the nation in 1917.

A source told the People newspaper the weekend was a ‘thank you’ for the Beckhams’ charity work over the years: “Sarah does a lot of charity work and has previously called on Victoria to help. They get on well and Sarah knows Victoria and David can be relied on to send signed books or jeans or give time if possible.”

“They don’t seem likely friends but the Browns have a lot of time for the Beckhams.”

“They are bound to have a great weekend together at Chequers.”

A Downing Street insider added that while his predecessor Tony Blair frequently had celebrity guests to stay when he was in the job, the Beckhams visit will be a one-off for Brown: “Gordon has made it clear he isn’t interested in using Chequers for schmoozing with celebs. You won’t see a host of C-List stars traipsing down there at his behest.”

“But David and Victoria have done some incredible work for cystic fibrosis charities, a cause very close to the Browns’ hearts, and the bond has grown.”

“They are now very good friends and an invite to Chequers was a natural step.”
