Andy Murray has become the first British man to reach a Wimbledon singles final in 74 years.

The British number one booked himself a place in Sunday's showdown by beating Jo-Wilfried Tsonga 6-3 6-4 3-6 7-5 on centre court.

Murray, from Dunblane in Scotland, is the first British man in a Wimbledon singles final since Henry "Bunny" Austin in 1938. He is hoping to become the first British man to win Wimbledon since Fred Perry 76 years ago.

Prime Minister David Cameron said: "It is great news that we have our first home-grown men's finalist at Wimbledon for over 70 years."

In a dramatic moment, Murray challenged the final point, which was called out, and was found to be right - taking the fourth set to win the match. The centre court crowd roared as the 25-year-old made history.

A visibly emotional Murray hugged Tsonga after the match. After his trademark "fingers-in-the-air" gesture, the tearful Scot paused, looking at the sky.

Afterwards, Murray said his emotions were "tough to explain", saying: "I'm so happy to be through."

Of the dramatic final point, he said: "I thought it was in, I knew when it left my racket it was good." He said Tsonga told him at the net that he thought it was wide: "He just said, 'well done'."

Asked about the pressure, Murray said: "There's a lot of pressure, when you're on the court there's a lot of stress but you have to just try and focus on the next point, not what's happened in the past."

Murray will face six-time champion Roger Federer in the final on Sunday. The Swiss star earlier beat world number one Novak Djokovic 6-3 3-6 6-4 6-3 to reach a record eight Wimbledon men's singles finals.
