The Paris Olympics have been marred by a doping controversy involving Chinese swimmers. British swimmer Adam Peaty has been vocal about the issue, calling for stricter action against doping. Peaty's comments come after China secured gold in the men’s 4x100 metres medley relay, where Britain finished fourth. Olympic swimmers have also spoken out about the controversy. Peaty specifically questioned the legitimacy of China’s victory and suggested that Chinese swimmer Qin Haiyang, who has a history of doping, should be banned from the sport. Peaty expressed his frustration with the current anti-doping system, stating he has no faith in it and urging authorities to take more decisive action.
