Andy Murray's imminent retirement will leave a gaping hole in British tennis after he competed at the top of the game for the last decade.
Here, Press Association Sport looks at the candidates who will be charged with filling the Scot's large shoes.
Kyle Edmund
Edmund has been carrying the hopes of a nation in Murray's absence and will now continue to do so, having already made waves in the men's game. He got to the Australian Open semi-final last year and also closed in on the top 10 after winning his first ATP Tour title. He has the game to compete at the top, with a forehand which is as big a weapon as anyone else on the tour has, but must make some improvements if he is to reach the level of his idol Murray.

Norrie, a South Africa-born Briton, has made a name for himself over the last 12 months as he has become established on the ATP Tour. Aged 23, he is ranked inside the top 100 and has just reached his first Tour-level final at the ASB Classic in New Zealand. He is on an upward trajectory and is comfortable on most surfaces.
Jay Clarke
Clarke has impressed Murray when the pair have practised together in the past. Aged 20, Clarke's progress has stuttered slightly after some impressive results on the Futures Tour, but he still has the potential to be a fine player. His physicality is a strong point and he is also an impressive doubles player.
Jack Draper
The son of former LTA chief Roger, Draper is a huge prospect for British tennis. The 17-year-old left-hander is making good headway on the junior circuit, reaching the final of Wimbledon boy's tournament last summer and becoming the youngest Briton to win a title on the Futures Tour since a certain Scot from Dunblane. The next few years, which will require significant physical development, will be crucial but he has potential to be a fine player.
