Ye's remarkable performance in the 400 metre individual medley, in which her final 50m was faster than Ryan Lochte, has raised many eyebrows, with a leading American coach describing what was a world-record breaking race as "disturbing".

But amid all those questioning whether or not the athlete was 'clean', Moynihan said today: "We know how on top of the game Wada are and Wada have passed her as clean. That's the end of the story.

"Let us recognise that there is an extraordinary swimmer out there who deserves the recognition of her talent in these Games."

Amid all the questioning over their athlete's achievement, China's anti-doping chief has hit out at the "biased" suspicions.

"I think it is not proper to single Chinese swimmers out once they produce good results. Some people are just biased," he said.

Ye's father said: "A lot of different people had to provide all kinds of help for this result to be possible."

He urged doubters to "look at her [drug] test results".

Adrian Moorhouse, who won gold for Great Britain at the 1988 Seoul Oympics, labelled suspicions over the teenager as "sour grapes" and believes swimming may have uncovered a phenomenon to match Michael Phelps.

Asked what he though of American coach John Leonard's use of the words "disturbing" and "unbelievable", Moorhouse said: "I think it is sour grapes. I think it's insulting actually. You saw the Chinese swimmers in 1990, they were the size of houses, this girl is quite small, light, she's just in good shape.
