Jenson Button will stay on at the McLaren team, having signed a multi-year contract with the British squad, it was confirmed on Wednesday.
The Briton joined McLaren as world champion in 2010, having clinched his first title with the Brawn GP squad back in 2009.
He has so far won four races with McLaren, and had been in talks about extending his deal for a while now, with both the McLaren and the driver having made it clear that he was to stay on.
On Wednesday, McLaren officially confirmed the news, saying Button has signed a new multi-year deal.
The Briton is currently in second place in the standings behind Red Bull's Sebastian Vettel.
"I've never felt more at home at a team than I do at Vodafone McLaren Mercedes," said Button.
"I've won four of the greatest races of my life here, I'm currently lying second in the drivers' world championship, and I feel that I'm driving better than ever.
"You can only achieve that with the right level of support - and I truly believe that the passion and determination to win are stronger here at Vodafone McLaren Mercedes than anywhere else.
"As a grand prix driver, those are incredibly powerful feelings to share and be part of, and they've only reinforced my desire to commit my long-term future to this team.
"I've made no secret of my ambition to continue winning races and world championships, and I fully believe this is the place where I can achieve those aims.
"We at Vodafone McLaren Mercedes know how to win, and we're busy refining an organisation that will enable us to keep on doing that for years to come."
Team boss Martin Whitmarsh added: "Jenson is a great driver and a great guy. In fact, I can safely say that he's one of the most capable and respected drivers we've ever had, and I'm therefore absolutely delighted that he'll continue to work with us into the future.
"He's a considerable credit to this organisation, and I'm proud to be his Team Principal.
"I feel sure that he'll now build on the considerable success he's already achieved with us, and will be even more successful with us in years to come.
"I think he and Lewis say it better than anyone. Their comments show just how much they respect and trust each other, and they once again continue to prove what we as a team have always known: that Vodafone McLaren Mercedes has the very best driver line-up in all of Formula 1."
Button's team-mate Lewis Hamilton also welcomed the news.
"It's great news that Jenson has chosen to stay with Vodafone McLaren Mercedes," he said. "Jenson has been a great person to work with, and a genuine team-player, from the moment we welcomed him on board.
"Vodafone McLaren Mercedes is a team with a unique and successful tradition in Formula 1, which I'm proud to be part of.
"It was the best moment of my career when I won the drivers' world championship with this team. Jenson and I are as hungry and as ambitious as ever to win races and world championships in the future."
