Team Sky’s manager Dave Brailsford is to face some serious questioning relating to a package which appears to be the main subject of the ongoing UK Anti-Doping investigation.

British sport minister Tracey Crouch made the announcement on Sunday that Brailsford will be among the six people set to appear before the culture, media and sport committee. The questioning which is scheduled to hold on Monday in Westminster is part of a long running investigation into the sport’s fight against doping.

The committee will ask questions based on evidences that had surfaced relating to Olympic champion Bradley Wiggins’ therapeutic use exemptions (TUEs), with an essential doctor’s note, permitting athletes to make use of medications that would otherwise be banned by the World Anti-Doping Agency. Also he would answer queries over a package that was delivered to Brailsford team by a British Cycling employee at the end of pre-Tour de France race in 2011.

A leaked document had earlier revealed that Wiggins was given approval to use the powerful corticosteroid triamcinolone before races in 2011, 2012 and 2013. It was reported in October that, at the final stages of the 2011 Dauphine Libere, Simon Cope, who was then the GB women’s team manager and academy, delivered a “Jiffy bag” containing triamcinolone to Team Sky doctor Richard Freeman.

Immediately the allegation was made public, the UK Anti-Doping Agency sprang into action and started investigations into the alleged cheating. UKAD sent investigators to the headquarters of both Team Sky and cycling’s national governing body, to collect relevant documents and interview the witnesses.

However, Team Sky’s boss, British Cycling, Cope, Freeman and Wiggins have strongly denied the allegations, saying that the content of the package was not triamcinolone.

Speaking to BBC 5 Live’s Sportsweek, the British sport minister said she would be following the committee hearing with “great interest.”

“If we want to continue to be successful in cycling, and to encourage more people to participate in cycling, it is important that the witnesses are transparent in the answers they give.

Brailsford will be asked some extremely important questions and he will have to justify himself and his actions, and it’s not for me as sports minister to say otherwise,” the minister said.
