Martina Hingis has revealed she tested positive for cocaine at this year's Wimbledon Championships, but denied taking the drug and announced her retirement from professional tennis.
A statement released to the media by the 27-year-old Swiss insisted she found the accusations "so horrendous and monstrous I've decided to confront it head on by talking to the press."
Hingis, a five-time Grand Slam champion and former Wimbledon winner, lost in the third round at the All England Club to Laura Granville.
Her statement continued: "My only performance enhancer is the love of the game.
"When I was informed I had failed my 'A' test following my defeat at Wimbledon I was shocked and appalled.
"I have no desire to spend the next seven years fighting doping officials.
"I'm frustrated and angry because I believe I'm 100 per cent innocent and accusations such as these don't provide me with the motivation to continue."
