More than 1,000 Russian athletes competing in summer, winter and paralympic sport were involved in or benefited from an "institutional conspiracy" to hide positive doping tests, according to a WADA report.
He added: It is impossible to know how deep and far back the conspiracy goes.
"For years worldwide sports competitions have unknowingly been hijacked by the Russians". He's been deeply involved in football in his country, too, despite the preliminary report previously suggesting he has a lot to answer for. The re-analysis will be to establish whether there was doping or whether the samples themselves were manipulated. The report also found the Russiandoping program corrupted the 2012 London Olympics on an "unprecedented scale".
The IAAF made no comment on the report but said that 53 per cent of the elite Russian athletes reported to the track and field governing body by McLaren had been sanctioned or face disciplinary proceedings.
McLaren's report alleged that more than 1,000 Russian athletes had benefited from a scheme to cover up positive doping tests, with some cases apparently linked to Russia's national biathlon team.
Speaking exclusively to Omnisport, McLaren said: "The individual response of an athlete if they are doping is [to] deny, deny, deny and deny it again, until you can't deny it any longer because it's obvious they're. lying".
Russia's track and field team was already banned from worldwide competition for doping and was barred from the Rio Olympics in August, but there is now growing pressure - not to mention anger - for more sanctions.
In 2007, Kazarin gave Stepanova testosterone injections to enhance her performance.
As McLaren laid bare almost all of the cards in his hand Friday, he made it undisputedly clear the extent to which one of the most powerful nations repeatedly cheated in sports.
McLaren-led commission claimed in particular that a total of 35 doping samples were concealed by Russian Paralympic sports between 2012 and 2015.
There are really only two possible explanations why two members of the Russian women's hockey team at the Sochi Olympics had urine samples that contained male DNA.
The world championships for bobsled and skeleton are scheduled to be held on the 2014 Olympic track from February 13-26. The sports, many of which receive considerable income from commercial activities, need to step up and help anti-doping organisations. At the time, he said that a "highly compressed timeline" - the report was researched and published in less than two months, going public shortly before the Rio Olympics - had forced him to be selective in what he analyzed. "I think banning clean Russian sportsmen is impractical and unfair".
Ahead of Friday, Bach had little idea what to expect. "This for me would present such aggravated circumstances, the logic would be life ban and exclusion from Olympic Games for life". Going forward, he will be co-operating with the International Olympic Committee commissions.
It involved top officials in the Russian Sports ministry, FSB intelligence service and the country's anti-doping agency.
The United States, Britain and Germany all swiftly condemned Russian Federation, while the International Paralympic Committee, which banned Russian Federation completely from the Rio Paralympics in September, called the McLaren findings "astonishing".
Top Russian officials dismissed the McLaren report, Deputy Prime Minister Vitaly Mutko telling the state news agency Tass that Russia would take legal measures to challenge the allegations.
Eating a striped candy cane Friday evening, Richard H. McLaren, the Canadian law professor who threw worldwide sports into tumult this year, exhaled, finally.
