Roger Federer has won the third set against Andy Murray in the Wimbledon final to take the lead by two sets to one.

Murray hit the ground running and broke the Swiss' serve twice to win the opening set 6-4. But Federer surged back in magnificent style to claim the second 7-5 and the third 6-3.

Roars of applause filled a packed arena as the Scot powered through against six-time champion Roger Federer as chants of "come on Andy" followed each point.

The Duchess of Cambridge and sister Pippa Middleton had front row seats in the Royal Box for the clash, excitedly talking and clapping during the games, along with Prime Minister David Cameron, who put his hand to his mouth in shock at one point as he watched intently.

England football star David Beckham and wife Victoria were also in the box for the match.

Despite rainfall at SW19 this morning, the match started with the Centre Court roof open.

If Murray wins the match, he will become the first British men's Wimbledon singles champion since Fred Perry won in 1936.
