Kamila Valieva's doping: another political-sports storm that leaves Russia at the center of the darkest scene. The CAS suspended the skater for four years who, at 15, was a figure in the 2022 Winter Olympics.

She was an icon of Russian sports and received by Vladimir Putin in the Kremlin. At the end of that year, she tested positive for trimetazidine, a substance that improves blood circulation and that the World Anti-Doping Agency (WADA) included in its list of prohibited products.
