Dick Pound, the hard-hitting former president of the World Anti-Doping Agency (WADA), is to head an independent commission investigating allegations of systematic doping and cover-ups in Russia.

Pound will chair the three-man commission and will be joined by fellow Canadian Professor Richard McLaren, a longstanding member of the Court of Arbitration for Sport.

It follows a programme broadcast by German TV station ARD on doping in Russia, which also alleged the IAAF world athletics body had failed to follow up on more than suspicious blood tests from more than 150 athletes including three from Britain.

A third member of the independent commission will be announced by WADA at a later stage.

Three senior IAAF officials, including the son of president Lamine Diack, have stepped down from their posts with athletics' world governing body, sources have told Press Association Sport.

Massata Papa Diack, who works for the IAAF as a marketing consultant, and IAAF legal adviser Habib Cisse have joined Valentin Balakhnichev, the president of the Russian athletics federation and the IAAF's treasurer, in agreeing to step down.

It comes days after German television station ARD broadcast three documentaries alleging that the IAAF officials were implicated in covering up the doping in Russia.

The move comes after the IAAF's executive board met on Wednesday - the governing body's ethics committee is investigation the allegations.

Warner urges swift action over doping allegations

UK Athletics chairman Ed Warner has urged world governing body the IAAF to act "swiftly and openly" with the allegations of systematic doping and corruption in Russian sport.

On Wednesday evening a Germany television documentary presented what it claimed was evidence of widespread drugs use.

The documentary also contended that the corruption extends beyond Russia and implicated the IAAF in covering up the abuse - "grave allegations" the independent ethics commission of international athletics' governing body is already investigating.

We don't need this in a year's time, we need this in a matter of weeks' time," Warner told the Guardian. We don't want to go into the 2015 athletics season with suspicion hanging over Russian athletes.

We can't be going into a European indoor championships in Prague in March with people looking at what they are watching and wondering if they can believe it.

The allegations that have been aired are clearly extremely serious and it's vital the IAAF doesn't pay lip service to any investigation and is seen to thoroughly scrutinise what has or has not gone on here swiftly and openly.

Canada was then awarded third place on appeal.

"It's heart-breaking," Aikines-Aryeetey said. "We found out when we were walking to the medal presentation."
