LONDON (REUTERS) - Several whistleblowers have approached the World Anti-Doping Agency (Wada) through a new programme set up after revelations of rampant state-sponsored doping in Russia, Wada president Craig Reedie said on Wednesday (March 29).

Wada this month launched its "Speak Up" secure digital platform for athletes and others to report anti-doping violations.

"We already have a number of whistleblowers speaking to us, so I am told," said Mr Reedie, speaking at the SportsPro Live conference.

He had no details about which sports or countries might be involved.

"The investigations people do not tell the president of the organisation what they are doing. And that's exactly the way it should be. That has to be confidential," he added.

Asked whether the world might be facing another big scandal, after Russian track and field athletes were banned from last year's Rio Olympics, Mr Reedie said he did not know but hoped not.

Wada recommended that the entire Russian team be excluded from Rio after an independent report by Richard McLaren, published just before those Games, accused the country of widespread state-sponsored doping.

The International Olympic Committee (IOC) rejected a proposed blanket ban and instead let international sports federations decide which athletes should be eligible to compete.

Russia has said it hopes to have the suspension of its anti-doping body Rusada lifted in November, but Mr Reedie said that could not be relied upon. He said a decision on Russian athletes' participation at next year's Pyeongchang Winter Olympics in South Korea needed to be made as early as possible and they could expect an aggressive programme of targeted testing in the run-up.
