It has been revealed that London's 2012 Olympics allowed Russian athletes to compete when they should have been suspended for doping violations.
An independent World Anti-Doping Agency report into the drug taking has found that a lifetime ban was recommended for five athletes, four coaches and another administrator. Seemingly the most high-profile name is Mariya Savinova, who won gold at London 2012 in the 800-meters event.
Mariya Savinova and Ekaterina Poistogova (800m), long-distance runners Kristina Ugarova and Tatyana Myazina, and current indoor champion Anastasiya Bazdyreva are specifically recommended for ultimate sanction.
