Russian Doping scandal

The final part of the McLaren report implicates four medallists at Sochi 2014 and five from London 2012.

Adding more details of the doping it revealed in July, the report described an "institutional conspiracy" involving Russia's secret service.

It said the athletes did not act alone but were part of a programme.

The report's author, Professor Richard McLaren, who was appointed by the World Anti-Doping Agency, said: "There was a cover up that evolved into an institutional and disciplined medal-winning strategy."

The 24-year-old won two silver medals in Rio but was booed by spectators and criticised by her rivals after she was allowed to compete, having initially been banned by the International Olympic Committee because of two failed drug tests.

Efimova tested positive for meldonium earlier this year, but had a suspension lifted by the sport's governing body, Fina, after the World Anti-Doping Agency admitted it was unsure how long the substance - which was only banned this year - stayed in the body.

Klishina, 25, was the only Russian accepted for the Olympic track and field but the International Association of Athletics Federations (IAAF) suspended her on Friday after new information on her doping record emerged.

After a day of hearings, the Court of Arbitration (CAS) announced that Klishina's appeal had succeeded and she "remained eligible to compete in the Olympic Games in Rio".

The IAAF has put a blanket ban on the Russia team but Darya Klishina had been cleared for Rio as the governing body was satisfied she was not doping.

However, the IAAF has now revoked the long jumper's eligibility based on new - but unspecified - information.

The 25-year-old insisted: "I am a clean athlete", and said she would appeal against the decision to the Court of Arbitration for Sport.

The International Paralympic Committee (IPC) had opened suspension proceedings following the McLaren report, and has now confirmed the ban.

The report, published last month, claimed Russia had operated a state-sponsored doping programme.

The International Olympic Committee (IOC) chose not to give Russia a blanket ban from the Olympic Games.

"The anti-doping system in Russia is broken, corrupted and entirely compromised," said IPC president Sir Philip Craven at a news conference on Sunday.

The threat is hanging over Russia after the World Anti-Doping Agency (WADA) revealed they would push for such a sanction if its latest Independent Commission found evidence of state-supported doping at the 2014 Winter Olympics in Sochi.

The results of the report are due to be revealed no later than July 15.

The appeal will be against the decision of the International Association of Athletics Federations (IAAF) to ban them from this year's Olympic Games in Rio de Janeiro.

ARAF secretary general Mikhail Butov revealed they are currently putting together a legal team to lead the appeal. 

Among those who may work on the case is London-based law firm Morgan Sports Law.

But whether they are allowed to represent Russia or not is unclear.

IOC president Thomas Bach said clean Russian athletes should take part under their own flag.

While athletics' governing body the IAAF says it will accept appeals on an "exceptional basis", for Russians to participate as "neutral athletes".

The International Association of Athletics Federation (IAAF) decided not to lift the suspension, imposed after accusations of state-sponsored doping.

Individual athletes can compete as neutrals if they prove they are clean.

The Russian president called on other bodies, including the International Olympic Committee (IOC), to intervene.

The IOC executive board said it would hold a telephone conference on Saturday to discuss the issue ahead of a full IOC summit in Lausanne on Tuesday.

This comes after the International Olympic Committee (IOC) revealed last week that retests of 454 samples using new technology had been completed in conjunction with the World Anti-Doping Agency (WADA), focusing on those who are likely to compete at Rio 2016.

A total of 31 athletes spanning 12 National Olympic Committees (NOCs) and six sports were implicated, the IOC said.

All those NOCs are currently being notified - with retesting of B-samples expected later this month and the names set to be formally confirmed soon after.
