Lewis Hamilton headed McLaren team-mate Jenson Button to an unexpected 1-2 finish in the Turkish Grand Prix after Red Bull colleagues Sebastian Vettel and Mark Webber contrived to throw away a similar result.

Hamilton spoke in Saturday's post-qualifying press conference of being ready to take any opportunity that might allow him to take his first win of the season but, after losing an early second place to Vettel during the pit-stops, the Briton appeared destined for third place.

All that changed 18 laps from home, however, when Vettel, having closed on Webber, decided to chance his arm on the run into turn twelve. Having got alongside the Australian, Vettel's car failed to fill the Red Bull-sized gap left by his team-mate and, edging right, made hard contact with its twin. Both cars headed into the copious run-off area, Vettel having spun several times, and narrowly avoided making secondary contact as Webber attempt to find his way back onto the track.

Vettel was out on the spot, clearly unhappy with what he felt was an error - a moment of madness - by his team-mate, but Webber was able to limp back into the action, eventually stopping for new tyres and front wing en-route to a consolation third place.

The big question however, is who was to blame?
