Lance Armstrong should have to repay his Tour de France winnings after being stripped of his seven titles, says race director Christian Prudhomme.

The International Cycling Union after ratifying a US Anti-Doping Agency report on him.

Tour director Prudhomme called the UCI's decision "totally logical".

And he added: "The UCI rules are clear. When a rider is disqualified, he must pay the prize money back."

Armstrong report key claims Achievements of USPS/Discovery Channel pro cycling team accomplished through the most sophisticated, professional and successful doping programme that sport has ever seen Armstrong's career at the team was fuelled from start to finish by doping More than a dozen former team-mates, friends and former team employees confirm a fraudulent course of conduct Armstrong acted with the help of a small army of enablers, including doping doctors, drug smugglers and others within and outside the sport and his team He had ultimate control over not only his own personal drug use but over the doping culture of the team Team staff were good at predicting when testers would turn up and seemed to have inside information Evidence is beyond strong and as strong as any case ever brought by Usada

It has been estimated that Armstrong won around £2.4m, external-link some of which was shared with his US Postal team-mates, for winning the Tour de France in seven successive years from 1999 to 2005.

It had read: "Father of 5 amazing kids, 7-time Tour de France winner, full time cancer fighter, part time triathlete."

Now it states: "Raising my 5 kids. Fighting Cancer. Swim, bike, run and golf whenever I can."

The American has 3.78m followers on the social networking site.

The UCI accepted the findings of the United States Anti-Doping Agency's (Usada) and called for Armstrong "to be forgotten".

The UCI management committee will meet on Friday to discuss the "exact sporting consequences" of the decision, including whether the titles and prize money will be re-distributed, but Prudhomme repeated his wish that the results from the Armstrong years are not reallocated.

"We hope that there is no winner in these editions," he said. "A formal decision must be taken by the UCI but for us, very clearly, there must be a blank record."

Armstrong has also been to Texas insurance company SCA Promotions.

The International Olympic Committee will await Friday's UCI meeting and further information before a decision is made on the bronze medal Armstrong won in the time trial at Sydney 2000. external-link

Armstrong overcame cancer to return to professional cycling. He has always denied doping but chose not to fight the charges filed against him.

Usada released a 1,000-page report this month which included sworn testimony from 26 people, including 15 riders with knowledge of the US Postal Service Team and the doping activities of its members.
