Russia's Deputy Prime Minister has delivered a stinging riposte after the coach of Kamila Valieva was accused of "chilling" behaviour towards the athlete.
The 15-year-old figure skater was controversially permitted to compete in this week's individual event, despite testing positive for the banned substance Trimetazidine.
The result was announced after she'd delivered a virtuoso display in the team event, becoming the first skater to land a quadruple axel as the Russian Olympic Committee seemingly won gold.
