British IndyCar driver Dan Wheldon has died following a huge accident at the Las Vegas Indy 300.
The Buckinghamshire-born star, 33, was one of 15 drivers involved in a crash at the second corner on lap 13 of the season-ending race.
Wheldon, who began IndyCar racing in 2002, was series champion in 2005 and won the Indy 500 in 2005 and 2011.
Lewis Hamilton, 2008 Formula 1 world champion, said: "This is a tragic loss at such a young age."
He added: "He was an extremely talented driver. As a British guy, who not only went over to the States but who twice won the Indy 500, he was an inspirational guy and someone that every racing driver looked up to with respect and admiration.
