Lance Armstrong: doping evidence jaw dropping - Brailsford

British Cycling's performance director Dave Brailsford describes the evidence that multiple-Tour de France winner Lance Armstrong doped as "jaw dropping".

The United States Anti-Doping Agency has accused the American cyclist of "the most sophisticated, professionalised and successful doping programme that sport has ever seen", and has banned him for life and stripped him of his seven Tour de France titles.

Brailsford, whose own outfit Team Sky won this year's Tour de France through Bradley Wiggins, told BBC Radio 5 live Sport it is up to the sport as a whole to demonstrate it is "credible" and that races can be won clean.

5 live Sport will have a special programme "Peddlers: Cycling's Dirty Truth" at 19:00 BST on Monday looking at the whole Lance Armstrong saga, including a full interview with Tyler Hamilton.
