Lewis Hamilton has moved 17 points clear at the top of the championship with a pole-to-flag victory at the Spanish Grand Prix, leading a Mercedes 1-2. Sebastian Vettel finished a disappointing fourth.
Lewis Hamilton wiped the floor with the opposition as he recorded his second victory of the season to retake control of the championship.
The defending world champion dominated and clocked a series of record laps as he registered the 64th victory of his career. Only Michael Schumacher on 91 has more, and came from Hamilton's 74th pole.
He joined seven-time champion Schumacher and two-time champion Finn Mika Hakkinen as a three-time winner in Spain.
Finn Valtteri Bottas came home second in the second Mercedes ahead of Dutchman Max Verstappen of Red Bull who resisted late pressure from four-time champion Sebastian Vettel, who led Hamilton by 17 points after the opening three races this year.
Vettel started third on the grid and moved up to second on the opening bend, but that was as good as it got for the German, who struggled on an afternoon where Hamilton was in imperious form.
As it happened:
LEWIS HAMILTON WINS THE SPANISH GRAND PRIX!
