The Russian Sports Ministry has announced that the director general of the country's anti-doping agency, Ramil Khabriev, has resigned.
The RUSADA chief has stepped down following a report from the World Anti-Doping Agency commission, which alleged that there has been widespread doping and cover-ups within Russian athletics.
The ministry announced that Khabriev handed over his resignation at a meeting that was attended by RUSADA's founders.
This week, a WADA delegation visited the department to inform them that drug testing should continue during Russian Athletics' suspension from international competition.
