Pressure continues to grow on the World Anti-Doping Agency (Wada) after UK Anti-Doping (Ukad) became the latest body to call for an independent investigation into events that led to 23 Chinese swimmers competing at the Tokyo Olympics despite recording positive drug tests.
The Chinese athletes were found to have traces of the banned substance Trimetazidine (TMZ) in their system when tested in 2021, only for Chinese authorities to say they were victims of contamination. On Monday Wada said it had no reason to question the Chinese verdict, despite the ultimate source of the contamination having never been found.
