John Coates

Coates, seen as a close ally of IOC President Thomas Bach, said he would be "very, very surprised" if the IOC overturned the decision of the International Association of Athletics Federations (IAAF).

"It's an International Federation's right to suspend a National Federation and I don't think we would overturn that at all," he said.

The Australian, who has described the Russian testing system as "rotten to the core", also welcomed similar investigations now taking place within other sports.

However he stressed that there is “no reason” to doubt the reasons given for the controversial transaction.

Coates, who heads up the IOC’s Coordination Commission for the Games in four years’ time, reiterated their co-operation with any investigations and claimed results of the probe being conducted by the Japanese Olympic Committee (JOC) could come within a month.
