Jenson Button made an emotional return to Brawn GP's factory in Brackley yesterday to pay tribute to the team which won the 2009 FIA Formula One Constructors' and Drivers' World Championships in Brazil on Sunday.

After a hectic forty-eight hours following Sunday's race which saw Button fly back from Brazil on team-mate Rubens Barrichello's plane and go straight to Bluewater Shopping Centre for a fan and media appearance, his priority was to get to the factory and speak to his team.

Champagne glass in hand and in front of his six race-winning trophies from the 2009 season, Jenson led a toast to the team's successes, gave his own heartfelt thanks for the team's contribution to his Drivers' title and paid tribute to those people who were no longer with the team after the difficult winter.

Entering the auditorium at the factory to the sound of his post-race 'We are the Champions' radio rendition Jenson received a resounding welcome from the 450 staff gathered to congratulate him.

"That's why I didn't have a voice for two days after the race!" said Button. "I'm really here today to say a massive well done and thank you to everyone at the team. We've worked so hard for these achievements for so many years. Some of us were here from the beginning back in 1998 and I arrived halfway through our journey in 2003 but everyone has put so much work in. I know that there have been a lot of very difficult times and over the winter there were times when we didn't think that we would be here at all. It's very sad that not everyone can be here who worked on this fantastic car. But the team had to become smaller to continue and together we produced a car that has been exceptional this season.

"To be able to achieve the Constructors' and the Drivers' Championships in our first year, especially after such a difficult winter, is an amazing achievement," he continued. "It's been a rollercoaster of emotions. The first few races were magnificent. It looked like it was a walk in the park but it really wasn't. Then we had some difficult races, especially myself but also as a team where we struggled. But we fought back hard and when we needed to improve the car, you guys did it. Rubens gave us two more wins in Valencia and Monza at an important time to boost our morale and prove just how quick the car was. We have a great leader, a fantastic leader, in Ross. The Big Bear can't be here today but I know that when he gets back, he'll be celebrating with you!

"We proved in Brazil last weekend that we deserve these Championships. We've fought so hard and a Championship season is about achieving the results when you need to. We've had some difficult races but we always did the best job that we could. So we should raise our glasses as the new Formula One World Champions of 2009. We've done what we set out to achieve. It really is going to take some time to sink that we are there. Celebrating our victories here with you today means so much to me and we are really going to enjoy this moment. Thank you so very much for your amazing contribution to our successes."
