Chinese gold medallist swimmer Ye Shiwen, 16, has denied taking drugs to enhance her performance, saying there was "no problem with doping".

A US coach earlier said Ye's record-breaking performance in Saturday's 400m individual medley was "disturbing".

But British Olympics chief Lord Moynihan said she was "clean" and "deserves recognition for her talent".

Ye Shiwen took seconds off her personal best to break the world record and win a gold medal in the 400m medley on Saturday, swimming faster in the last 50m than the winner of the men's event.

There is no evidence against her and all medal winners are drug-tested.

But Ye Shiwen said: "There is no problem with doping. The Chinese team has a firm policy so there is no problem with that."

And British Olympic Association chairman Lord Moynihan said the World Anti-Doping Agency (Wada) was "on top of the game".

"She's been through Wada's programme and she's clean. That's the end of the story. Ye Shiwen deserves recognition for her talent," he told a press conference
