Damian Collins, the chair of the Culture, Media and Sport select committee, has said that Sir Bradley Wiggins will not be questioned by MPs over doping in sport as he is an “individual athlete”.

UK Anti-Doping has so far been unable to prove what was in a medical package delivered to Wiggins before the 2011 Tour de France. However, Collins said that the committee’s job is the hold “British Cycling and Team Sky to account because they receive public money and to question UKAD about their power and resources”.

He added that it is not the committee’s job to look into the medical records of individual athletes.

UKAD has been looking into allegations that the package Wiggins received contained the corticosteroid triamcinolone, a drug used to treat asthma that can have performance-enhancing side effects and is banned from competitions.

While Wiggins did receive medical permission to use the drug before the 2011 Tour de France, he and Team Sky principal Sir Dave Brailsford have said that the package contained fluimucil, a legal decongestant.

Last week the chief executive of UKAD, Nicole Sapstead, said that there are no records of what drugs Wiggins received at the 2011 Dauphine bike race. She said that the organisation has spent 1,000 man-hours looking into what the package contained but has not managed to make any headway.

Speaking last week Sapstead said, “We are not able to confirm or refute that it contained Fluimucil. We have asked for inventories and medical records and we have not been able to ascertain that because there are no records.”

Team Sky, which was launched by the former British Cycling performance director Brailsford in 2010, has restated its confidence that “there has been no wrongdoing” and said it was “a clean team”.
