Kimi Raikkonen has been declared the winner because the result is counted back two laps before the red flag was shown.
That was just after Coulthard pitted from the lead. So Raikkonen wins, followed by Fisichella, Alonso and Coulthard.
Coulthard, Raikkonen or Fisichella could yet be the winner - it depends on the lap from which the result is taken, which is dictated by the rules.
Race stopped: Alonso, whose accident was caused by hitting a tyre from Webber's crashed Jaguar, is sitting down beside the track. He is helped on to a stretcher.
Fisichella will have won if the race is to be stopped - and his car is on fire in the pit lane.
Lap 54: Frentzen is now closing on Coulthard. Fisichella takes the lead as Raikkonen loses grip on the way into Mergulho. Webber crashes heading onto the pit straight, leaving debris strewn across the track. The safety car is out again.
Raikkonen pits. Alonso crashes in the same place as Webber and the race is stopped - the result will go back one lap if the race is declared over and Fisichella will have won.
Lap 53: Fisichella is right behind Raikkonen and looks set to take the lead. The Bridegstone tyres - used by Jordan and Sauber - have an advantage at the moment over the Michelins - on the Renaults and McLarens.Trulli pits.
Lap 52: McLaren are getting ready for a stop - it is Coulthard, who comes out behind Raikkonen, Fisichella and Alonso.

Lap 49: Schumacher pits in the Williams for fresh wet tyres and more fuel.
Lap 48: Coulthard has a 18-second lead over Raikkonen - it all now depends on which McLaren driver has lucked into the best strategy.
Lap 47: Barrichello slows and is out of the race - his terrible luck in Brazil hits again. This is the ninth year in a row he has retired in his home Grand Prix.
Lap 46: Barrichello's Bridgestone intermediates are working a lot better than Coulthard's Michelins at the moment - a fact underlined by the pace of Fisichella on Bridgestones in fifth place.
Lap 45: To huge cheers from the Sao Paulo crowd, local boy Barrichello takes the lead after Coulthard, clearly in trouble with his tyres, makes a mistake in Turn One and runs wide. Barrichello immediately sets a new fastest lap, 2.5secs quicker than Coulthard.
Lap 44: The track is now reasonably dry - apart from the infamous Turn Three. Coulthard and Barrichello are lapping nearly two seconds quicker than anyone else.

Lap eight: The safety car is due in at the end of this lap, when racing will start. Fisichella pits for fuel, rejoining at the back.

Lap five: The rain has stopped but conditions still appear to be poor, with a lot of spray being thrown up by the tyres.

1740: The race is scheduled to start at 1800. However, it is raining in Sao Paulo and the cars are likely to be led away by the safety car if race officials decide against a delay.
The drivers are concerned about poor drainage at Interlagos, and they have only intermediate tyres available with relatively light treads because of the new rules.
