THE HAGUE, March 7 (Xinhua) -- Cyclist Michael Boogerd needs to be fully open on what he knows about doping in cycling, said Dutch Minister of Health, Welfare and Sport Edith Schippers on Thursday in newspaper De Telegraaf.

"He must not only clean his own house, but he must unveil in detail what has happened in cycling during his career," Schippers was quoted as saying. "He is obliged to do that for the new generation."

On Wednesday Boogerd admitted the use of doping during the last 10 years of his career. The 40-year-old former rider, who was professional from 1993 until 2007, declared to have used EPO, blood transfusions and cortisones.

Boogerd is the eighth former Rabobank cyclist to confess. In recent months the pressure on him to confess was increasing in Dutch media and finally he did. He stated that he was not willing to name people who also used doping or people who helped him with taking doping.

"I am responsible for my decision to take doping and I don't want to make someone else responsible for that. I'm not a traitor and keep my principles intact," said Boogerd.

"He needs to think about what he is doing to the new generation of cyclists, who work hard and are bothered by the past now," reacted Minister Schippers. "Moreover, he must think of the survival of the sport."

The Ministry of Health, Welfare and Sport finances the anti-doping committee of the Dutch cycling federation KNWU. Riders and other members of the cycling world are able to anonymously tell their story to that commission.
