The Wimbledon championships will protect its squeaky clean image with enhanced anti-doping and anti-corruption measures for this year's 130th tournament.

Tennis was rocked by allegations of match-fixing on the eve of this year's Australian Open and suffered another blow to its integrity when former Wimbledon champion Maria Sharapova said in February she had failed a drugs test.

At a news conference overnight announcing yet another substantial hike in prize money, the All England Club pledged to beef up its safeguards against sport's two biggest threats.

Richard Lewis, chief executive of the All England Club says whether it's integrity or anti-doping the club believes it should enhance what it is doing.
