Andy Murray, who is bidding for a place in the semi-finals of Wimbledon today when he takes on Fernando Verdasco, can expect some high-profile support on Centre Court.
Among those invited to the Royal Box are England manager Roy Hodgson and former Manchester United manager Sir Alex Ferguson.
The latter is a particularly big supporter of his fellow Scot, interrupting Murray's press conference following last year's US Open victory along with Sir Sean Connery to congratulate him.
Also in attendance will be England rugby union head coach Stuart Lancaster and Manchester United defender Nemanja Vidic.
While Murray will surely appreciate the support, he may have preferred not to have received a good luck message from David Cameron.
The Prime Minister tweeted this morning: "The sky over Downing St a little grey right now. Let's hope it clears up for @andy_murray to win at #Wimbledon. Best of luck Andy."
Offers of support from the PM have been dubbed the 'Curse of Cameron' after a number of sporting stars crashed out following them. Earlier this week, Robson lost after a tweet from Cameron while in 2007 the England rugby team faltered at the World Cup after a tweet.
