The stewards overseeing the Belgian Grand Prix at Spa-Francorchamps have decided that no-one was to blame for the opening lap incident at Les Combes, which claimed four cars, including Britons Jenson Button and Lewis Hamilton.
Having qualified a lowly 14th, Button had made a decent start, taking advantage of Hamilton's slow getaway, Adrian Sutil's spin and Brawn team-mate Rubens Barrichello's anti-stall problems to be challenging Heikki Kovalainen out of Raidillon, but was tagged by rookie Romain Grosjean as he turned into Les Combes, spinning across the pack as a result.
As the Brawn ended its race in the barriers, with Grosjean nosing his Renault in alongside, Hamilton - taking avoiding action - left Jaime Alguersuari with nowhere to go, the Spaniard riding over the McLaren's rear wheel and pushing both into the wall a little further through the turn.
All four drivers were out on the spot, and forced the stewards to deploy the safety car which ultimately decided the destiny of the race, as Kimi Raikkonen made full use of the restart to power past polesitter Giancarlo Fisichella.
Button's DNF was his first of the season, and appeared to open the door to his world championship rivals, but only Sebastian Vettel managed a decent haul of points, joining Raikkonen and Fisichella on the podium, while Barrichello salvaged two points from his poor start and Mark Webber failed to trouble the scorers for a second straight race.
