Briton Lewis Hamilton has become the youngest man to win the Formula One drivers' world championship aftering finishing fifth in a dramatic rain-hit Brazilian Grand Prix, only clinching the title on the final lap.
Only on that amazing final lap did Hamilton regain the place he needed when German Timo Glock lost 18 seconds in his Toyota and slipped behind him.
Until then, the title looked to be going to hometown hero Felipe Massa, who won the race.
Hamilton's triumph made him first Briton to take the world title since Damon Hill in 1996 and the first McLaren champion since Finn Mika Hakkinen in 1999. He is Britain's ninth champion.
The previous youngest champion was two-times champion Spaniard Fernando Alonso of Renault who was 24 years, one month and 27 days old when he won the title in 2005.
Massa had been hoping to be the first Brazilian champion since Ayrton Senna in 1991.
