Lance Armstrong has been notified by cycling's world governing body, the UCI, that he has been stripped of all the titles he won after July 1998 and the American has three weeks to appeal.
The 41-year-old Armstrong had his seven Tour de France victories scratched from the records and was banned from cycling for life in October after the UCI ratified the United States Anti-Doping Agency's sanctions against him.
The International Olympic Committee said this month it would wait for the UCI to notify Armstrong that his titles were being taken away and give him the right to appeal before stripping him of his 2000 Sydney Olympics bronze medal.
Armstrong, who won the medal in the individual time trial, has repeatedly denied doping and never tested positive for drugs.
His accusers, however, said Armstrong - one of the world's most famous athletes who is also well known for his cancer-fighting charity work - was not only a willing participant, but the ringleader, ordering team mates to cheat.
