Aquatics GB, the governing body of British swimming, has said it is “extremely concerned” by the case of 23 Chinese swimmers who tested positive for a banned substance but were allowed to compete at the Tokyo Olympics.
On Monday, the World Anti-Doping Agency (Wada) defended its actions in the affair, saying it “would do exactly the same thing” if it faced such an issue again. But voices from across the sport and beyond have questioned the process which saw the results of positive tests for Trimetazidine (TMZ) kept secret and a verdict of contamination accepted despite an investigation conducted by Chinese secret services being unable to explain how it happened.
