Hamilton wins 3rd world title

Defending champion Lewis Hamilton secured his third world title on Sunday when he raced to victory in the United States Grand Prix.

The 30-year-old Briton came home 2.850 seconds clear of his Mercedes teammate Nico Rosberg to deliver his 10th victory of the season.

Hamilton now has an unbeatable total of 327 points, moving him beyond the reach of both Rosberg, and four-time champion Sebastian Vettel of Ferrari.

Hamilton's success enabled him to equal the record of Jackie Stewart as the only Britons to win three drivers' world titles and the first to win two championships in succession.
