Lewis Hamilton lost the lead of the world championship after retiring from a sobering Austrian Grand Prix for Mercedes, as Max Verstappen took an unexpected victory for Red Bull.
Hamilton was in fourth place, after a strategy error by Mercedes and tyre problems, but looking at retaining his lead when he retired with a loss of fuel pressure with eight laps to go.
His retirement, with title rival Sebastian Vettel finishing third in his Ferrari behind team-mate Kimi Raikkonen, puts Vettel into a one-point lead heading into next weekend's British Grand Prix.
Mercedes will leave Austria and head to Silverstone with plenty on their minds as they ponder how what had looked set to be an easy one-two on a weekend they had dominated fell apart.
Their problems handed a first win on their home track to Red Bull, for whom Verstappen drove beautifully to control the race once Mercedes hit their problems, well out of reach of the pursuing Ferraris.
