Sports minister Vijay Goel has made it clear that only ‘clean’ athletes will represent India at the Rio Games. The minister said it is the responsibility of the National Anti-Doping Agency to ensure that all sportspersons representing the country at the Olympics are drug-free. He said the law will take its course in dealing with drug cheats and those who have conspired to shame Rio-bound athletes like shot-putter Inderjeet Singh and wrestler Narsingh Yadav.
