The Beijing Games will be the cleanest Olympics in years despite concerns about the effectiveness of tests for blood doping, the head of the World Anti-Doping Agency says.
WADA president John Fahey says cheats are more likely to be caught by the doping agency this year than ever before.
WADA was established in 1999 after the previous year's Tour de France was rocked by the Festina affair, which
exposed systematic blood doping within the sport.
Fahey rejected suggestions the agency's EPO tests had been proven fatally flawed by independent studies.
The have been media reports of WADA laboratories were classing positive tests for EPO as negatives but Fahey says while they do not ignore such evidence, experts had cast doubt on the external research.
