Armstrong will not take part in process that will 'demonise selected individuals'

Chief executive Travis Tygart is confident the United States Anti-Doping Agency can continue its investigation to clean up cycling without the help of Lance Armstrong.

The disgraced cyclist confirmed yesterday he will not be willing to testify under oath to USADA officials after admitting to doping during each of his seven Tour de France wins in a televised interview with Oprah Winfrey last month.
