Athletics superpower Russia is running out of time to eradicate doping and may not be able to send a track and field team to this year's Rio Olympics, Dick Pound, chair of the World Anti-Doping Agency (WADA) independent commission, has said.
"There seems to be some evidence that they're just changing deck chairs on the Titanic," he told an anti-doping conference.
Russian athletes were banned from international competition after a report by Pound's commission revealing widespread doping and graft with involvement of Russian and international athletics officials. Russian athletics authorities were ordered to carry out sweeping reforms to allow a lifting of the ban.
"My guess is Russia may not make it back for Rio. The IAAF and WADA are not going to risk their reputations by rolling over and playing dead," Pound said referring to the sport's world governing International Association of Athletics Federations.
Last week a German TV documentary contained fresh allegations of malpractice in Russia's anti-doping system.
Amongst the claims in the prgramme were that Russian coaches suspended in the worst corruption and doping scandal to hit the sport were still working in athletics, while others continued to provide banned substances to athletes.
"We said to them at the time if you stop complaining about the (WADA) report you have a chance. Whether their progress is sufficient enough? I don't think they are devoting all their time and energy into getting where they ought to be.
"We knew it would be a stretch for them but if they devoted themselves, heart and soul, to getting it done, it would be possible. Yet here we are four months later and I think somehow they must have convinced themselves that it would go away.
"Clearly it's not going to go away. Neither WADA nor the IAAF are going to buy a band-aid solution," he told Reuters.
The ARD reports in recent months on doping in Russian sport were based on information provided by whistleblowers Vitaly Stepanov, who formerly worked for Russia's anti-doping agency, and his wife Yuliya, an 800 metres runner banned for doping.
WADA chairman Craig Reedie, who also addressed delegates, said he had appealed to the IAAF and the International Olympic Committee to allow Yuliya to compete at the Rio Olympics.
Reedie said that contrary to media reports, WADA had also offered financial support and relocation to the Stepanovs who currently live in an undisclosed location outside Russia.
"For the record, I, WADA and the anti-doping community are very grateful," Reedie said.
Branded as traitors at home, Vitaly, Yuliya and their young son have been in hiding since the documentary aired in December 2014. They have changed residences nine times and are living under assumed names.
"Without them it would have been a case of 'Niet, not possible, it's lies'. They gave us hard evidence," Pound said.
Russia, second to the U.S. in the sport's pecking order, will be allowed to return to competition, including August's Rio Olympics, when it proves to WADA and the IAAF that it has met a series of conditions regarding its anti-doping operation.
The doping and corruption scandal is amongst the worst in athletics' history and has put in question lucrative global sponsorship deals as well as results and medal awards in past international competitions.
Reedie said governments and sports governing bodies, had to invest more to ensure their sports were clean.
"Here we are in sport awash with money, but I'm very perplexed there isn't more cash for anti-doping," he said.
