Britain's Andy Murray has become the world No1 for the first time in his 11-year career, ending Novak Djokovic's two and a half year reign at the top of the world rankings.
Murray usurped the Serb after his Paris Masters semi-final opponent Milos Raonic withdrew ahead of the match with injury.
Djokovic, who had topped the rankings for 122 weeks, lost to Marin Cilic in the quarter-final of the ATP Tour event, opening up the opportunity for Murray to climb past him to the top of the leaderboard.
Murray has become the first British player to be ranked No1 in the world since computerised rankings began in 1973.
Murray has enjoyed the best year of his career to date in 2016, with a second Wimbledon title proving to be the highlight of a season in which he has set a new personal record of 73 wins.
The 29-year-old has earned over $10m (£8m) so far, making it his highest earning campaign to date.
He has staged an assault on Djokovic's No1 ranking in recent months, reaching 11 finals in past 12 events.
John Isner will be Murray's opponent in the Paris final after the American beat Cilic 6-4, 6-3 in Saturday's other semi-final.
