The ramifications of the Russian doping scandal continue to resound as the country's sports administration attempts to clean up its tarnished image.

On Monday, suspended deputy sports minister Yuri Nagornykh resigned following allegations that he covered up doping cases at the 2014 Winter Olympics.

Nagornykh was the most prominent among a group of Russian sports officials suspended in July by order of President Vladimir Putin following the publication of a World Anti-Doping Agency report which accused them of covering up hundreds of doping cases, including at the Sochi Games.

Nagornykh had vehemently denied allegations of a state cover-up.

A document signed by Prime Minister Dmitry Medvedev and posted on the Russian government's legal database on Monday stated that Nagornykh was removed from his post at his own request, without providing further details.
