Adam Peaty questioned China’s relay victory on the final night of swimming at the Paris Olympics, saying “there’s no point winning if you’re not winning fair”.

China took gold in a thrilling men’s 4x100m medley relay race, beating the United States into second and France third, with the British quartet finishing fourth.

Two of the four gold medallists, Qin Haiyang and Sun Jiajun, were among the 23 Chinese swimmers who reportedly returned positive doping tests prior to the Tokyo Olympics.

They were not banned because the China Anti-Doping Agency determined they had unintentionally ingested the substance because of contamination.

“If you touch and you know that you’re cheating, you’re not winning, right?” said Peaty.

“I don’t want to paint a whole nation or group of people with one brush, I think that’s very unfair.

“But there have been two cases of it and it’s very disappointing.”
