Lewis Hamilton stormed to his fourth victory of the season by fending off a late attack from team-mate Nico Rosberg in the Spanish Grand Prix at Circuit de Catalunya on Sunday.
Crucially, the result moved the Briton to the head of the Formula 1 World Championship standings for the first time this season.
The two Mercedes drivers continued their dominant start to the season by locking out the front row during qualifying. For a while on Saturday it looked as if Rosberg – who had finished second to his team-mate in the previous three races – might be able to regain the upper hand, but Hamilton charged to his fourth pole position of the season.
Red Bull Racing's Daniel Ricciardo annexed third on the grid ahead of the impressive Valtteri Bottas in his Williams, but no-one could get within one second of Hamilton's pole lap time.
On Sunday Hamilton converted his pole position into an immediate lead. Rosberg slotted into second place ahead of Bottas, Ricciardo and the Lotus of Romain Grosjean, who seized fifth despite a dramatic tyre-smoking lock-up under braking for the first right-hand corner.
Hamilton established an advantage of about two seconds over Rosberg. At the first round of tyre changes, Hamilton had small cause for concern because his stop was slightly slower than his team-mate, but when Rosberg emerged from his pit visit two laps later, the Briton was still in the lead.
However, they were now on different tyre strategies, Hamilton on the softer-compound rubber and Rosberg on the theoretically slower hard variants. The fact the German went two laps longer on his first set meant Hamilton had to work hard to build a bigger cushion before his team-mate switched back to the softer rubber in the closing stage of the race.
