Adam Peaty has questioned the legitimacy of China's victory in the men's 4x100 metres medley relay - warning Olympic officials to 'wake up and do your job'. Qin Haiyang and Sun Jiajun helped their nation claim gold but were two of 23 Chinese swimmers who tested positive for the banned substance trimetazidine prior to the Tokyo Olympics. The pair cleared to compete on the basis of a finding they had unknowingly ingested the drug via contaminated food. The issue heavily overshadowed the build-up to Paris 2024 and appeared to lead to mistrust from several swimmers. #adampeaty #swimming #olympics #paris2024 #news #china #teamgb #olympicswimming
