The Russian figure skater Kamila Valieva, whose positive doping test as a 15-year-old dominated headlines at the 2022 Winter Olympics, has been banned for four years by the court of arbitration for sport.

The ruling also means all Valieva's results achieved after her failed test on 25 December 2021 have now been stripped from the record books.
