Mercedes Lewis Hamilton held off Max Verstappen's Red Bull for victory in an extraordinary finish to the Bahrain Grand Prix.
Verstappen actually took the lead from Hamilton with four laps to go but handed the position back because he had overtaken by running off the track.
The move - an order from race control - cost the Red Bull driver the victory. Verstappen never quite got close enough again to challenge Hamilton.
It was a remarkable climax to a tense and thrilling strategic battle that bodes well for an epic season between the two men.
Verstappen complained over the radio about being ordered by his team to hand the lead back, but was told they had no choice.
The drivers had been referred by the race director before the race to a rule that says they cannot not leave the track and gain a lasting advantage, and that officials can give them the "opportunity to give back the whole of any advantage gained by leaving the track".
