“The fight against doping and illegal gambling remains the absolute priorities for the IOC,” he said.

Olympics chief Rogge, who took the reins from the late long-serving president Juan Antonio Samaranch after his step-down in 2001 said, “In the battle against doping, we will increase tests before and after the Games with targeted testing and get National Olympic Committees to increase tests during the Games and we will also test samples that have been taken at previous Games.”

“In terms of irregular betting and match-fixing we will rely on in depth monitoring and communicate with bodies. We are fighting against threats that sport face but also good governance of sport is crucial. Sports organizations should have rigorous internal and external audits,” added the IOC president, who is due to step-down in September next year after 12-year tenure.
