Vitaly Mutko, a Russian deputy prime minister has announced his resignation from his role as the 2018 World Cup organising committee's chairman less than six months before the tournament begins in Russia.
The decision comes the same month as his lifetime ban from the Olympics following an investigation into
allegations of state-sponsoring doping.
"I have decided to file the claim in the CAS tomorrow," The Straits Times quoted Mutko as saying.
Mutoko will be replaced by Alexei Sorokin, who is Russia 2018 chief executive and has also take his place on the FIFA council, reports said.
