China doping row to raise tension at Paris pool

Some of the world’s best in the sport have criticised anti-doping authorities and raised concerns about the competition’s integrity following revelations in April that 23 Chinese swimmers were allowed to compete at the Tokyo Games despite testing positive for the banned heart medication trimetazidine (TMZ).
