Four officials to face IAAF hearing into alleged doping cover-up

Liliya Shobukhova won the London Marathon in 2010 and came second a year later

The son of ex-world athletics chief Lamine Diack is one of four officials facing a disciplinary hearing this week over an alleged doping cover-up.

Papa Massata Diack, a former consultant for the IAAF, and ex-IAAF anti-doping director Gabriel Dolle are charged with breaches of the IAAF's code of ethics.

Former All-Russia Athletic Federation chief Valentin Balakhnichev and coach Alexei Melnikov are also in the dock.

None are expected at the three-day hearing, which starts on Wednesday.

The charges relate to the payment of about £435,000 that Russian former London Marathon winner Liliya Shobukhova allegedly made to have her doping violations covered up.

Her 38-month ban from track and field was reduced by seven months after she turned whistleblower for the World Anti-Doping Agency.

A decision from the hearing, which will be held in London, is expected in early January.

Russia have been banned from international athletics competition after a report by Wada's independent commission alleged they were guilty of "state-sponsored doping".
