Katie Ledecky hopes for ‘clean’ swimmers at Olympics after Chinese doping row

• Chinese swimmers tested positive before Tokyo Games
• US star looking to add to seven Olympic golds

Katie Ledecky referenced allegations around Chinese doping in her opening press conference at the Paris Olympics on Wednesday, saying she hopes to face clean" athletes in the coming weeks.

Twenty-three Chinese swimmers tested positive for the banned drug trimetazidine months before the last Olympics, in Tokyo, but were still allowed to compete after the World Anti-Doping Agency accepted an explanation from Chinese authorities that the athletes had stayed at a hotel with a contaminated kitchen.
