Cycling's governing body says the World Anti-Doping Agency (Wada) is no longer welcome at its events. The International Cycling Union (UCI) has accused Wada of leaking a confidential report about this year's Tour de France.
UCI president Hein Verbruggen insisted that Wada had leaked the report to the media on purpose.
"I do not say Wada are always unprofessional but this shows an unprofessional attitude," he said.
Verbruggen, who is a leading figure in the International Olympic Committee, told the Guardian newspaper: "The report was leaked purposely".
The UCI claims the report, which was published in French newspaper L'Equipe, contains "certain inaccurate points".

A spokesman for the organisation said Wada would remain banned "until the matter is resolved".
The UCI is angry that the report was leaked on Monday, the day before Wada was due to pronounce on the use of corticosteroids, which are used to treat asthma.
The issue came to a head when then Tour de France leader Igor Gonzalez de Galdeano tested positive for asthma drug salbutamol.
Wada said he would be positive under their rules, but the UCI cleared him.
The leaked report says the way riders are notified about being tested allows room for cheating.
Cyclists in the Tour are told five minutes before a time-trial stage start if they will be tested, and 20 minutes before the end of a road race stage.
Observers also reported a casual attitude within Tour procedures, saying some cyclists were spending 20 minutes in team buses before being tested.
'Discrediting'
Cycling has been hit by a series of doping scandals since 1998 when the Tour de France was nearly derailed after doping agents were found in a car belonging to the Festina team.
Wada was set up following the scandal to help clean up sport around the world worldwide.
The UCI is one of only a few sports which has yet to sign the world anti-doping charter.
Verbruggen resigned from Wada last year for reasons which remain unclear.
After the Galdeano affair he accused Wada chairman Dick Pound of "behaving like a sheriff in the wild west.
"He shoots any target he can, left and right. I'm fed up of him discrediting my athletes."
