Kate Middleton has joined eight-time Wimbledon champion Roger Federer for a behind-the-scenes look at the work of the “amazingly professional” ball boys and girls who are a key part of the tennis tournament – which takes place next month.The Princess of Wales and Roger, both 41, were guests at a training session for some of the young hopefuls aiming to be chosen for the around 250 ball boy and girl roles during the championships running from July 3-16 in south-west London.

Kate, who is patron of The All England Lawn Tennis and Croquet Club which hosts the Grand Slam event, said: “Wimbledon is renowned for its amazingly professional ball boys and ball girls, the amount of work it takes, it’s incredible to see it behind the scenes. “With all the discipline and everything you’ve learnt, you’ll be able to take it into so many other parts of your life – things like confidence, and that feeling of pride with being on any of the courts is such a big moment.” Roger said: “This is proper practice.

I’m really impressed at how much effort and training goes into being a ball kid during the championships. “I used to be a ball kid in Basel when I was nine or 10 and, as I have always said, once a ball kid always a ball kid.” Their meeting is included in a short YouTube video filmed at the All England Club and its indoor tennis centre earlier this month.

Kate can be seen taking part in a doubles rally with the 20-time men’s singles Grand Slam winner on No 3 Court before watching the children in a training session.
