Motor Sport: McLaren's championship leader Lewis Hamilton will not be penalised after a stewards' enquiry into his driving at last weekend's Japanese Grand Prix.
Toro Rosso's Sebastian Vettel, who collided with Red Bull's Mark Webber in that race while following Hamilton behind the safety car, had a 10-place penalty on the Chinese Grand Prix starting grid replaced with a reprimand.
Having escaped sanction, Hamilton can become Formula One's first rookie champion if he wins in China on Sunday.
