Mercedes' Lewis Hamilton sprays champagne atop the podium after winning the Spanish F1 Grand Prix in Montmelo, Spain yesterday

Lewis Hamilton extended his lead in the drivers' world championship to 17 points yesterday when he roared to an imperious victory as Mercedes scored a one-two triumph at the Spanish GP. The defending four-time world champion dominated from start to finish and clocked a series of record laps for his second successive win. It was the 64th victory of his career — only Michael Schumacher on 91 has more — and came from his 74th pole. He joined seven-time champion Schumacher and two-time champion Mika Hakkinen as a three-time winner in Spain.
