Great Britain's Sir Mo Farah says he is a "clean athlete" after a leaked report suggested his American coach may have broken anti-doping rules to boost the performance of some of his athletes.
Farah said "If US Anti-Doping Agency or any other anti-doping body has evidence of wrongdoing they should publish it and take action rather than allow the media to be judge and jury."
The coach in question, Alberto Salazar, has been under investigation since a BBC Panorama programme made allegations about drugs use at his US training base.
The investigation into Salazar, who is also a consultant to UK Athletics (UKA), has been under way since at least June 2015.
33-year-old Farah said in a statement "It's deeply frustrating that I'm having to make an announcement on this subject. I am a clean athlete who has never broken the rules in regards to substances, methods or dosages and it is upsetting that some parts of the media, despite the clear facts, continue to try to associate me with allegations of drug misuse.
"As I've said many times before we all should do everything we can to have a clean sport and it is entirely right that anyone who breaks the rules should be punished."
Salazar and Farah deny they have ever broken anti-doping rules.
