Kamila Valieva was plied with 56 medicines aged 13 to 15

Kamila Valieva, the teenage Russian ice skater stripped of her Olympic medal after a positive drugs test, was given 56 different medications between the ages of 13 and 15 in what a leading anti-doping chief described as a “sickening” treatment programme.

Details of a positive test for a banned drug were revealed shortly after Valieva, then 15, had helped Russia win gold in the team skating event with a stunning performance on the ice.
