Novak Djokovic has sparked controversy by claiming that men should be awarded more prize money than women after similar comments from the chief executive of Indian Wells, Raymond Moore.
The world No1 and 11-time grand slam winner said women deserved the money they got, but men should be rewarded with more because their game attracted more viewers.
Tennis was the first sport to pay equal prize money to women at the US Open in 1973 after being put under pressure from the reigning champion Billie Jean King, although it was not until 2007 that Wimbledon became the last of the grand slam tournaments to follow suit. But how does that compare to other sports?
Athletics first paid equal prize money at the 1995 world championships, the same year figure skating followed suit, and the London marathon has always had equal prize money since it was first staged in 1981.
Elsewhere, a BBC survey in 2014 found that out of the 35 sports which have prize money, 25 pay an equal amount to men and women. Those that do not are some cycling disciplines including the Tour de France, cliff diving, cricket, darts, football, golf, squash, surfing, snooker, and ski jumping.
Of those sports, the biggest difference can be found in golf, where the winner of The Open championship this year will receive £1.15m in comparison to just £298,000 for the women’s event. The winner of the men’s snooker world championship will receive £300,000 and their female equivalent just £1,500.
