Yesterday Pippa Middleton kept her sister the Duchess of Cambridge company in the Royal Box as they watched Andy Murray lose to Roger Federer.

Federer played an incredible game and beat Britain’s Andy Murray 4-6, 7-5, 6-3, 6-4 and matched Pete Sampras’s record of seven Wimbledon singles titles.

Being interviewed after the game, he said of his opponent. ‘He [Murray] has done so well over the years and it [his tears] shows he cares so dearly about his tennis.

‘He will win one grand slam at least. I hope so. It’s worked out here that I have played my best tennis in the semis and the final.

‘I couldn’t be more happy. It feels so familiar and it’s a great moment. It’s amazing. It equals me with Pete who is my hero, and the world No1, they don’t get gifted to you.’
