Britain's Andy Murray has been officially confirmed as the world's number one men's singles tennis player in new rankings published by the Association of Tennis Professionals (ATP) today.

Switzerland's Roger Federer also falls out of the world top 10 for the first time in over 14 years since October 2002.

Murray becomes the 26th player to rise to number one in the Emirates-sponsored list.

Aged 29, he also becomes the oldest first-time number one since 30-year-old John Newcombe in June 1974.

It comes over seven years after the three-time Grand Slam winner first reached the number two slot in 2009.

Murray has had a superb season, claiming a second Wimbledon singles triumph before a successful defence of his Olympic title.

Murray has then won tournaments over the last month in Beijing, Shanghai, Vienna and Paris.

Serbia's Novak Djokovic slips down into second place, 405 points behind the Scot.

Switzerland's Stan Wawrinka, Canada's Milos Raonic and Japan's Kei Nishikori occupy the next three places.

But Federer, a former number one for 302 weeks, slips down seven positions from ninth to 16th. 

It marks his lowest position since May 28 in 2001 and brings to an end a remarkable 14 years in the top 10.

Croatia's Marin Cilic also rises three places from 10th to seventh, while Spaniard Rafael Nadal falls two from sixth to eighth.
