On December 19, Sky principal David Brailsford will appear before a parliamentary committee to give explanation about the mysterious medical package that Bradley Wiggins received during the 2011 Critérium du Dauphiné. UCI president Brian Cookson hopes that Brailsford will be transparent, he tells The Times .

Cookson can’t undertstand Brailsford who refuses to reveal the content of the package.

“I would hope that there is full disclosure to the select committee,” Cookson said. “I am surprised that one particular package has been singled out and I don’t understand why that should be, unless there is someone who has leaked this [and] presumably has some sort of reason to suspect that there is something in it that they would rather not go into public.”

The United Kingdom Anti-Doping Agency has opened an investigation into the package.

Simon Cope who worked for the British Cycling Federation, delivered the package in 2011 when he flew to Switzerland and then travelled to France. At the time Cookson was chairman of British Cycling but he refuses that he knew anything about the content.

“No, absolutely not, but I’m not surprised that packages are taken and delivered to teams from time to time, whether pedals, shoes, medical products, I’m sure that’s happening all the time with all the teams because they are always on the road,” he said.

“I don’t understand why there is a mystery about it, to be quite honest. One would imagine there is a record of this.”
