Russian athletes banned from Rio 2016

Russian track and field athletes will remain banned from the Olympics following claims the country ran a state-sponsored doping programme. The Russian Olympic Committee (ROC) and 68 Russian athletes attempted to overturn the suspension, implemented by the body that governs world athletics. But the Court of Arbitration for Sport (Cas) has ruled it can stand.
A handful of Russian athletes could still compete as neutrals at the Rio Games, which start on 5 August.
