JENSON BUTTON - F1 WORLD CHAMPION

Fifth place at the Brazilian Grand Prix was enough to cement the world title for Jenson Button yesterday, 21 years after he first took to the race track in a kart.

An understandably emotional Button said the race was 'the best of my life', as key rivals Sebastian Vettel finished fourth from 15th on the grid and Rubens Barrichello's chances were ended by a puncture.

"This was the best race I've driven in my life," Button told Autosport after the race. "I know because of the emotion that's involved in it, but also because I knew what I had to do - I did it, and that is why I am sat up here as world champion. I am going to enjoy this moment very much. The people around me have been so supportive. I might have come across like I don't care about this in the past, but that was just me keeping a face. It shows a weakness if you show it is hurting or stressful, but I can say it now, it was very a tough few months and I needed the people around me, especially the team to fight for this. Today I didn't win the race but I did best I could with the car and it felt like a win to me. I am the world champion - I am not going to stop saying it!"

Well done Jenson, we always knew you had it in you!

The new Brawn GP team set up by Ross Brawn after Honda sold out is also celebrating, having clinched its first Constructor's Title in its first year of competition.
