Button has outperformed team-mate Hamilton in 2011
BBC COMMENTATOR MARTIN BRUNDLE'S VIEW
"It is significant that 2011 was Jenson Button's second year at McLaren.
"He's a fully-fledged and well-respected team driver who is knocking on the door of becoming team leader with his calm and professional delivery of results.
"In changeable conditions, as we saw yet again in Canada, he simply finds grip no one else knows about.
"Jenson's reputation is even higher now than when he won the 2009 championship for Brawn, and he says he's a better driver too.
"He is second in the championship, the first time a team-mate has beaten Hamilton."
BUTTON TAKES OUR DRIVERS' TEST
What three words would you use to describe what it's like to be a Formula 1 driver?
Wow, wow - and wow.
What is the biggest perk of the job?
Racing a Formula 1 car against the best drivers in the world - it's as simple and amazing as that.
How would you like to be remembered as an F1 driver?
As a world champion and someone who worked very hard to build a strong team.
What is your most embarrassing sporting moment?
Luckily I haven't had too many. I'd say forgetting my bicycle saddle when I went to compete in a triathlon.
Ayrton Senna or Alain Prost?
In my view it would be wrong to try to choose between them. They both had some amazing qualities.
Spa or Monaco?
For me, Spa is more of a fun circuit because you can race and overtake. Monaco is intense but I prefer a circuit where you can really race.

If you weren't an F1 driver what would you be?
I get asked this question a lot and I really struggle because I really can't envisage ever being anything else other than an F1 driver.
Who is the greatest sportsman of all time?
That's also a tough one because there are so many great sportsmen and sportswomen in their respective disciplines.
I would have to say that Michael Schumacher's dedication to the sport has shown that he is both talented and willing to give everything to be the best.
I'll also say Lance Armstrong because of how many times he has won the Tour de France.
What would be your perfect day off?
Lying on a beach with my girlfriend, a bit of reading, a bit of scuba diving, then a nice massage.
Where is your favourite place to go on holiday?
The south of France. It's great that it's right on my doorstep. Great food and great beaches.
What is your favourite item of clothing?
A pair of white Converse trainers
What is your favourite music to drive to?
I like old tunes when I'm driving. They're fun and uplifting. Billy Ocean, that kind of thing.
Which famous person - dead or alive - would you like to have dinner with and why?
The Queen. I think she has an amazing story, and yes, she can bring the corgis, no problem.
Tell us something about yourself that most F1 fans might not know.
In my hometown there is a pub named after me - The Frome Flyer on Jenson Avenue. How cool is that?!
Steve McQueen or Paul Newman?
Steve McQueen, king of cool. Le Mans is the only racing movie that is totally realistic.
Boxers or briefs?
Boxers for sure.
Angelina Jolie or Keira Knightley?
Angelina. Apart from the obvious, I really admire her. She does a lot of great humanitarian work and it's important to give something back.
James Bond or Austin Powers?
James Bond, but only Daniel Craig because he does the rough and tough stuff. I think every guy likes to imagine themselves in the James Bond guise.
