Lance Armstrong has severed all ties with the cancer charity, Livestrong. He took the decision "to spare the organisation any negative effects" in the wake of the scandal surrounding the cyclist.
The Texan was stripped of his seven Tour de France titles after an investigation by the United States Anti-Doping Agency (USADA) found him guilty of using performance-enhancing drugs.
Armstrong resigned as chairman of the charity on 17 October, and replaced by Jeff Garvey, as the scandal intensified and the 41-year-old has now stood down from the board of directors.
Garvey said: "Lance Armstrong has chosen to voluntarily resign from the board of directors of the Livestrong Foundation to spare the organisation any negative effects as a result of controversy surrounding his cycling career."
