SCOTS marathon runner Freya Murray has called for a rethink on how drug test results are dealt with after fellow athlete Paula Radcliffe moved to "categorically" deny any form of cheating.

Radcliffe, a three time London Marathon winner, spoke out after saying she had been "effectively implicated" in a parliamentary anti-doping inquiry.

Ms Murray, who was the first Briton home in the London 2012 Olympics event, after taking a place vacated by Radcliffe's withdrawal said: "It's not fair that someone's reputation is being questioned unless there is very strong evidence against them."

Radcliffe, 41, who in her autobiography admitted having samples frozen so tests can be conducted in the future, said questions raised during a parliamentary select committee "effectively implicated" her in the Sunday Times' allegations of blood doping in athletics.

She also strenuously denied on Twitter the use of an injunction "super or otherwise" adding: "Not needed when you have the truth."

Jesse Norman MP had suggested winners and medallists at the London Marathon and "potentially British athletes" were under suspicion.

Mr Norman, chairman of the Culture, Media and Sport Select Committee questioned David Kenworthy, chairman of UK Anti-Doping during an anti-doping inquiry on Tuesday when he seemed to raise suspicions about a prominent British marathon runner.

He asked Mr Kenworthy during the House of Commons hearing: "When you hear that the London Marathon, potentially the winners or medallists at the London Marathon, potentially British athletes are under suspicion for very high levels of blood doping....When you think of the effect that has on young people and the community nature of that event, what are your emotions about that, how do you feel about that?"

While Radcliffe was not specifically named, she is the only British athlete since 1996 to triumph at the event.

Ms Radcliffe released a statement running to nearly 2000 words denying cheating "in any form whatsoever at any time in my career" adding that she was "devastated that my name has even been linked to these wide-ranging accusations".

Ms Murray is one of eight British athletes, including Mo Farah who want more transparency and want anti-doping blood test data to be made public. She and the other seven have all released their own blood-test data.

She stresses that slightly abnormal 'off-scores', an analysis of blood cells used by experts to determine doping, are not evidence of cheating and believes that no athlete should be implicated for doping, unless there is "very strong evidence".

The 31-year-old said: "I know her and I have always looked up to her, and admired her, especially her strong views on anti-doping and do feel it is slightly unfair that she feels she is having to explain something she shouldn't have to.

"And it's a shame she feels her name and her reputation has maybe been questioned. For someone who has been very outspoken about anti-doping, she hasn't failed any test, so you can't take her down unless there is clear evidence she has cheated.

"Having an abnormal off-score doesn't mean that you have cheated. And if people are having to come out and make statements to say they have not been cheating and explain their scores then that can be unfair.

"If going forward, there were clear boundaries and everyone has to have their off-score published, and that is investigated before that happens, then that is a fairer way to go about it.

"Nobody should be implicated unless there is serious evidence that they have definitely been cheating. But for anyone where it is found there is serious evidence that they have been cheating, they should be banned."

Ms Radcliffe said: "I have campaigned long and hard throughout my career for a clean sport. I have publicly condemned cheats and those who aid them. These accusations threaten to undermine all I have stood and competed for, as well as my hard earned reputation.

"Whilst I have the greatest of respect for anyone responsibly trying to uncover cheating in sport, and of course for Parliament itself, it is profoundly disappointing that the cloak of Parliamentary privilege has been used to effectively implicate me..."

Mr Norman denied he had used privilege to implicate any particular individuals.
