LONDON - This year's men's and women's singles champions at Wimbledon will each receive nearly $3 million, as the Grand Slam tournament increases overall prize money by 5 per cent.

The All England Club also announced Tuesday that it is increasing spending to fight match-fixing and doping, although it provided no figures.

Total prize fund is going up to 28.1 million pounds ($40 million) for the grass-court championships.

The prize for the singles champions has been raised by 6.4 per cent, or 120,000 pounds ($175,000), to 2 million pounds ($2.9 million). Last year, Novak Djokovic and Serena Williams each collected 1.88 million pounds ($2.74 million) for winning the titles.

First-round losers, meanwhile, will receive 30,000 pounds ($43,000).

Over the past five years, total prize money at Wimbledon has nearly doubled, going up by 92 per cent. The highest increase was in 2013, when the prize fund went up by 40 per cent.

The 130th edition of the tournament will be played at the All England Club from June 27-July 10.

The U.S. Open continues to be the Grand Slam tournament paying the highest prize money. Last year, it paid out a total of $42.3 million — including $3.3 million to each of the singles champions.

Prize money has been increased 14 per cent for next month's French Open to a total of about 32 million euros ($36 million). The singles winners will each earn 2 million euros ($2.25 million).

Wimbledon, meanwhile, said it is beefing up measures to protect "the integrity" of the tournament, following allegations of match-fixing ahead of the Australian Open in January and Maria Sharapova's positive drug test at the Melbourne tournament.

Chief executive Richard Lewis said Wimbledon would implement stricter accreditation procedures and enhanced monitoring and analysis of betting patterns to detect any suspicious activity.

"We just think that whether it is integrity or anti-doping we should enhance what we are doing," Lewis said.

Two data feeds will be provided on each court, including for qualifying, with video available of every match to help with any investigation.

The issue of match-fixing came to the forefront during the Australian Open when the BBC and BuzzFeed alleged that tennis authorities suppressed evidence and failed to thoroughly investigate possible fixing involving 16 players. That led tennis' governing bodies to launch an independent review of the sport's anti-corruption group, the Tennis Integrity Unit.

Lewis said Wimbledon would also spend more on drug-testing, beyond the anti-doping program run by the International Tennis Federation.

"We have a lot of confidence in the anti-doping program," Lewis said. "It would be wrong to go into details."

All England Club chairman Philip Brook said it would be a "great shame" if Sharapova is unable to play at Wimbledon this year, but that the ITF's disciplinary procedure must take its course. The 2004 Wimbledon champion has been provisionally suspended after her positive test for meldonium and is scheduled to face an ITF hearing.

Security measures for Wimbledon will also be increased following the attacks in Paris, Brussels and elsewhere.

"We know what's happened around the world in the last 12 months so there will be a little bit more overt security," Brooks said.
