Jenson Button happy after signing new McLaren contract

Jenson Button says he is looking forward to "a good few years" working with McLaren, after signing a multi-year contract on Wednesday.

The British driver also defends team-mate Lewis Hamilton, saying criticism of his driving style will not slow him down at this weekend's Japanese Grand Prix.

Button is the only driver with a mathematical chance of depriving Red Bull's Sebastian Vettel of a second consecutive world title.
