Sepang, Malaysia  - Jenson Button in a Brawn GP was declared the winner of Sunday's Malaysian Grand Prix after the race was stopped in the 33rd lap after torrential downpours made a continuation impossible.

Button was leading from Toyota's Timo Glock and Nick Heidfeld in a BMW-Sauber when race director Charlie Whiting suspended the race.

Whiting decided later that the race could not be restarted.

However, as three quarters of the race had not been completed, only half of the championship points will be awarded.

Button leads the standings with 15 points from his team-mate Rubens Barrichello, who has 10. dpa
