Lewis Hamilton took his first win of the season in the Turkish Grand Prix, but it was a clash between the pace-setting Red Bull team-mates that was the real talking point of the event,
Pole-sitting Red Bull driver Mark Webber led until team-mate Sebastian Vettel's lap 40 passing move, which ended with the German out of the race and the Australian down in third.
Both drivers blamed each other for the incident, which left Hamilton and McLaren team-mate Jenson Button out front.
The McLaren duo then began some close racing of their own. As light drizzle started, Button got a run on Hamilton towards Turn 12 with nine laps to go.
With Hamilton defending the inside, Button went right around the outside - giving him the racing line and the lead at Turn 13.
But Button's lead lasted only the length of the pits straight, with Hamilton diving back to the inside into the first corner and through a narrowing gap to take the lead.
With McLaren frantically urging its drivers to conserve fuel thereafter as it kept an eye on some consumption issues, that was the end of the battle.
