Russian figure skater Kamila Valieva will learn on Monday if she can continue to compete at the Winter Olympics, after the teenager's failed drugs test came to light.

The 15-year-old is due to compete in the individual event, starting on Tuesday, and has been considered an overwhelming favourite for gold.

Valieva tested positive in December for trimetazidine, a medication that is used to prevent angina attacks but is on the World Anti-Doping Agency (WADA) banned list because it improves blood flow to the heart.

The result came from a sample taken on December 25 during Russia's national championships, but Valieva was allowed to come to Beijing 2022 after she appealed against the outcome and RUSADA – Russia's Anti-Doping Agency – lifted a provisional suspension on February 9.

The International Testing Agency (ITA) said that decision was reached on the grounds of a "reasoned decision" that has not been disclosed.

A dazzling Valieva helped Russian Olympic Committee win team figure skating gold on Monday, but the medals for that event have yet to be handed out.

She has continued to train on the Olympic ice, but the youngster's active participation in the rest of the Games hinges on a Court of Arbitration for Sport (CAS) hearing on Sunday evening in Beijing, with the outcome due to be announced on Monday afternoon in the Chinese capital.

The International Olympic Committee (IOC) and WADA appealed against the RUSADA decision, and they were joined in that action on Saturday by the International Skating Union (ISU).

CAS, in a statement issued on Saturday, confirmed a three-person panel would deal with the IOC, WADA and ISU procedures together, with the hearing held by videoconference.
