Wimbledon player access limited

Access to players in the changing rooms at Wimbledon will be subject to greater restrictions this year, as part of an anti-corruption drive.

"We have had discussions about tightening (dressing room security) for this year," chief executive Ian Ritchie told BBC Radio 5 Live's Sportsweek.

"The players are extremely aware of the rules of betting and I know that that has been brought to their attention.

"And in the usual way we will be monitoring the betting as it goes on."

This is in response to a four-month review, published by the International Tennis Federation, the ATP, the WTA Tour and the four grand slams, which stressed that while "professional tennis is neither systematically nor institutionally corrupt", steps needed to be taken to protect "vulnerable" players from corrupt approaches.

"Professional tennis, like other sports, is experiencing threats to integrity from a range of issues," the review panel revealed in its 66-page report.

"There are strong indications that some players are vulnerable to corrupt approaches and others outside of tennis are using them to make corrupt gains from professional tennis," the statement continued.

Meanwhile, Martina Navratilova has called for lifetime bans for players who deliberately lose matches, ahead of the London tournament which begins on Monday.

"I don't think it's been going for very long, but it's really difficult to track," declared the nine-times Wimbledon singles champion.

"The only way to really check on it is by betting patterns - and obviously there have been some betting patterns which are very disconcerting.

"I think the only way to really deal with it would be to make extremely severe penalties.

"And to me any player that would lose a match on purpose - they are done for life, lifetime ban."
