Britain can expect to be represented by a 'clean team' at the London Olympics, British Olympic chief Colin Moynihan declared.
Lord Moynihan said:
"I am as confident as I can be that we will have 550 athletes who have fully understood the consequences of taking performance-enhancing drugs and that have not done so.
"I absolutely hope that all the work that has been done with them... will ensure that we have a clean team which we have been successful in doing on many occasions in the past."
