NEW YORK • Dick Pound, author of the report that revealed shocking levels of doping in Russian athletics and led to the suspension of Russia's athletics federation, says the upcoming second part will be even more explosive.

In it, World Anti-Doping Agency (Wada) looks into possible corruption within the International Association of Athletics Federations (IAAF), added Pound, a former Wada president.

He told the Independent newspaper: "People will say 'How on earth could this happen?'

"It's a complete betrayal of what the people in charge of the sport should be doing."

The second part of the inquiry paved the way for the arrest of former IAAF president Lamine Diack and ex-head of anti-doping Gabriel Dolle, and is now in the hands of the French authorities.

The French are investigating the IAAF and the results of the 15,000 blood samples which were leaked by the organisation in August.

Pound, who has yet to see the analysis of blood samples while the French prosecution is ongoing into Diack, Dolle and Habib Cisse, a legal adviser at the IAAF to Diack, said studying that material would probably delay publication of the report.

He said: "It would be nice to have it done in 2015. But it looks more likely to be January.

"One fear is that if we issue it on the Friday before Christmas, for example, no one will notice it and we want to have the maximum impact and deterrent."

For now, Russian athletes are banned from competing internationally until they comply with Wada rules. Pound said despite his push for a ban from next year's Rio Olympics, he expects they will be allowed to take part.

"It's my expectation that Russian athletes will be in Rio... and I'd be very surprised if the organisations that have to declare them compliant again would not be cooperative in making that happen," he added.

Pound vowed to keep up the fight against widespread doping.

"This is a proper fight and no matter how many sad tales you hear of tainted supplements, that's nothing compared to the planned, organised and well-financed cheating that occurs.

"That's not accidental. So we're turning over rocks people don't want to be turned over."

Pound said he hopes that the impact of the second part of the Wada report will spur support for the anti-doping movement and lead to funding for further probes.

He also singled out Kenya after allegations of corruption by Athletics Kenya officials. He said: "It wouldn't surprise me if Wada did end up doing an investigation on the ground in Kenya, especially with the level of denial from the sport and the government authorities amid pretty obvious evidence."
