Lewis Hamilton has secured a third Formula 1 world championship title with victory in the United States Grand Prix.
Hamilton, who also scooped the world championship in 2008 and 2014, won the title in dramatic fashion after an incident-packed US Grand Prix. After leading early on, Hamilton fell to fourth, and despite fighting back through the field after several safety car periods, he looked destined to finish behind Mercedes team-mate Nico Rosberg.
However, his German team-mate ran off the track and lost time late in the race, handing Hamilton the race win and a big enough points buffer to be guaranteed the world title despite there still being two races to run of the 2015 F1 season.
Sebastian Vettel, racing for Ferrari, was the only other driver who could beat Hamilton to the world title but, despite challenging for the race win, he could only finish third, which was not enough to deny Hamilton.
"This is the greatest moment of my life," said a clearly emotional Hamilton after the race. "I can't really find the right words at this second to tell you how it feels. I’m sitting here just thinking about my first British [karting] championship where my dad and I drove home singing ‘We are the Champions’. At the time, of Great Britain.
