Following the withdrawal of Honda from the sport in December 2008, he was left without a drive for the 2009 season, until Ross Brawn led a management buyout of the team in February 2009, and Button suddenly found himself in a highly competitive, Mercedes-engined car.
He went on to win a record-equalling six of the first seven races of the 2009 season, securing the World Drivers' Championship at the Brazilian Grand Prix, having led on points all season; his success also helped Brawn GP to secure the World Constructors' Championship.
In 2004 he finished 3rd in the World Drivers' Championship, with only the two Ferraris ahead of him.
BAR was subsequently renamed Honda for the 2006 season, during which Button won his first Grand Prix in Hungary, after 113 races.
For 2010, he moved to Mc Laren, partnering fellow British racer and former World Champion Lewis Hamilton.
After finishing fifth for the team in 2010, Button finished the 2011 season as runner-up.
From the 306 races that Button has started he has won 15, with a total of 50 podium finishes.
he began karting at the Clay Pigeon Raceway at the age of eight, after his father bought him his first kart, and made an extraordinarily successful start.
In 1989, aged nine, he came first in the British Super Prix.
He first drove in Formula One with Williams for the 2000 season.
The following year he switched to Benetton, which in 2002 became Renault, and then for the 2003 season he moved to BAR.
At the end of 1999, Button had his Mc Laren test prize at Silverstone, and also tested for the Prost team.
