The 33-year-old royal, who attended the Centre Court alongside his wife, the Duchess of Cambridge, responded to an announcement about industrial action by workers on the city's transport network by pretending to make a dash for the exit.

The prince's behaviour prompted laughter from his wife and other people sat in the Royal Box, which also featured retired soccer star David Beckham and William's cousin, Zara Phillips.

Meanwhile, Prince William recently reunited with his old Eton school friend Eddie Redmayne at a charity polo game, where the prince was competing and helping to raise money.

The royal was seen engaged in conversation with the award-winning performer - who played Professor Stephen Hawking in 'The Theory of Everything' - and his new wife Hannah Bagshawe.

The Hollywood star had previously described Prince William as a "lovely man".

He said: "I'm pretty sure Will was more intimidating than I was.

"I don't think I intimidated anyone in my life. I haven't seen him since school, but he was a lovely man."
