The World Anti-Doping Agency has confirmed they will not appeal against the United States Anti-Doping Agency's sanctions against Lance Armstrong.

USADA recommend that all Armstrong's results from 1 August, 1998 were expunged from the record books, including his seven consecutive Tour de France `wins` from 1999 to 2005, as well as handing the 41-year-old a life ban from cycling.

The International Cycling Union (UCI) last week ratified the sanctions imposed by USADA, who concluded Armstrong and his United States Postal Service team ran "the most sophisticated, professionalised and successful doping programme that sport has ever seen".

But while the UCI did highlight some criticisms of USADA, WADA appear unequivocal in their support of the findings.

Commenting on the decision, WADA President John Fahey said: "WADA has no such concerns as to the complete process and the overwhelming weight of evidence. Rather it is of the opinion that the actions of USADA have highlighted the need in all cases for athletes to be able to come forward with evidence that will help rid sport of doping cheats."
