FIA chief cleared in Las Vegas GP interference probe

FIA president Mohammed Ben Sulayem was on Wednesday cleared of accusations that he interfered with the organisation of last year's inaugural Las Vegas Grand Prix.

The governing body's ethics committee said "a robust and wide-ranging independent review spanning 30 days, which included interviews with 11 witnesses" took place.

"Allegations against the FIA president were unsubstantiated," the body said in a statement.
