Moynihan confident over doping
Athletes warned samples will be kept for many years in effort to catch cheats
Britain's Olympic chief does not envisage any high-profile athlete failing a drugs test in London because they would have to be the "dopiest of dopers" to do so.
Lord Moynihan says most athletes who had taken banned performance-enhancing substances would have done so some time ago so the drugs were out of their system, or taking masking agents to cover the traces.
"If you get caught at a Games you are the dopiest of dopers, you really are" said Moynihan, chairman of the British Olympic Association.
"If you take something like steroids say three weeks before the Games knowing there is going to be testing you are going to have a brick loose.
"Anyone who has gone out of their way to cheat is likely to have done it quite a long time ago or taking masking agents. You would have to be foolish to get caught doping actually during the Games."
Moynihan added that athletes should also be aware that samples would be kept for many years so that advances in testing technology can find evidence of doping - even gene doping, where DNA can be manipulated to try to gain an advantage.
"The good thing about keeping these samples is that in the years ahead we will find out whether gene doping etc is an issue today when it become much easier to detect in the future."
