Anti-doping scientist quits on 'muzzling'

A leading scientist says he is resigning from an expert body on biological passports in sport because he is being "muzzled".

Dr Michael Ashenden accused the anti-doping movement of fostering a culture of "omerta" - a term describing the pact of silence in the mafia.

He said the imposition of a new confidentiality clause in his contract was an attempt to silence him.

Dr Ashenden explained his position to our correspondent Matt McGrath.
