Derval O’Rourke: Wada must chase other cheats

Derval O’Rourke has called on the World Anti-Doping Agency (Wada) to pursue drug cheats around the world with the same vigour displayed in uncovering illegal practices in Russia.

Yesterday the Court of Arbitration for Sport rejected the appeal by 68 Russian track and field athletes seeking to overturn a ban imposed by the IAAF following allegations of state-sponsored doping and cover-ups.

The ruling could influence whether the entire Russian Olympic team is banned from the Games.
