Jenson Button has confirmed that he has signed a deal with McLaren for next season.
The 33-year-old has repeatedly stated his allegiance to the British team, although an automatic extension clause had remained inactivated until now.
Speaking to Sky Sports News ahead of this weekend's Singapore Grand Prix, the 2009 world champion announced: "It's done, I'll be here next year."
Button, who joined McLaren after Brawn GP were bought out by Mercedes in 2010, remained tight-lipped when asked if he would still be at McLaren in 2015, when the team switches to a Honda engine.
