The World Anti-Doping Agency is under mounting pressure to launch fresh drug cheat sanctions against Russia after the deadline to hand over data from its Moscow anti-doping laboratory expired.

Travis Tygart, chief executive of the US Anti-Doping Agency, branded the situation a "total joke and an embarrassment" for the beleaguered governing body, which he said should "stop being played by the Russians" and immediately reinstate a ban on the country's athletes.

The Wada president Sir Craig Reedie later expressed bitter disappointment that Russia had missed the deadline. Rusada, the doping control agency, could now be told the sanctions will be reinstated when an independent panel meets to review the case on January 14.

Reedie said: “I am bitterly disappointed that data extraction from the former Moscow Laboratory has not been completed by the date agreed by Wada's ExCo in September 2018. Since then, Wada has been working diligently with the Russian authorities to meet the deadline, which was clearly in the best interest of clean sport. The process agreed by Wada’s ExCo in September will now be initiated.”

Sanctions against cheating doping control agency Rusada were controversially lifted in September on the basis that Wada would be granted full access to its labs by the end of December.
