Jenson Button has clinched his first Formula One title after capitalizing on his rivals' miscues to finish fifth in a Brazilian Grand Prix won by Mark Webber, AP reported.
The fifth-place on Sunday was good enough to give Button an insurmountable 17-point lead in the drivers' standings ahead of the season-ending race in Abu Dhabi on Nov. 1.
His closest competition for the title, Brawn GP teammate Rubens Barrichello, started from pole but finished eighth after a puncture on his home track. Red Bull's Sebastian Vettel was fourth.
Webber took his second F1 win ahead of Robert Kubica of BMW Sauber and defending champion Lewis Hamilton of McLaren at the 2.6-mile Interlagos track.
