Lap 59: In a dramatic late twist at the start of the final lap, the right front suspension of Raikkonen's car buckles and his McLaren spins off the track.
It leaves the charging Alonso clear to claim victory for Renault, giving his title hopes a massive boost.
Heidfeld is promoted to second in the Williams, and Barrichello snatches the final podium place for Ferrari.
Coulthard has an impressive fourth for Red Bull, which would have been better had he had not picked up a pitlane speeding penalty.
Lap 57: Leader Raikkonen's right front tyre is starting to deteriorate badly, but he is still keeping the car on the road.
Lap 56: Raikkonen is looking like he will hold on for victory, if his McLaren's fading tyres do not give up at this late stage. The gap is 3.5 seconds.
Lap 55: Raikkonen appears to be doing just enough, as Alonso only manages to cut his lead by 0.4 seconds.
Lap 54: Alonso has reduced the gap to leader Raikkonen to 4.4 seconds.
Michael Schumacher runs off the track in the Ferrari but does not lose sixth place.

Heidfeld's third place is also coming under threat from Barrichello's Ferrari.
Lap 52: Earlier damage to Raikkonen's car and tyre wear look to be beginning to tell.
He now leads Alonso by just over six seconds and the Spaniard's Renault is closing fast.
Lap 51: Massa runs off into the gravel, allowing Montoya to snatch eighth place from him.
Lap 50: Heidfeld makes his third and final stop in the Williams. Leader Raikkonen is slow, giving Alonso a scent of victory.
Lap 49: Michael Schumacher has jumped Massa's Sauber during the stops.

Lap 44: Alonso, promoted into the lead for the time being after Raikkonen's pitstop, sets the fastest lap of the race so far.
Lap 43: Raikkonen comes into the pits for his second stop. He appears to have broken the right barge board on his McLaren, which could well cost him time.

Lap 40: Michael Schumacher's Ferrari and Montoya's McLaren almost touch tyres as the Colombian unsuccessfully challenges the world champion for seventh place.
Lap 39: Championship leader Alonso is on course to finish second, which would minimise the effect of a Raikkonen victory in the context of the title race.
Lap 38: BAR have not been competitive on their return from a two-race ban. Button is 11th and Sato 13th.
Lap 36: Raikkonen is still looking good for victory.
A couple of off-course moments have raised doubts about the McLaren's tyres, but the Finn is 15 seconds ahead of Alonso's Renault and lapping at a similar pace.

Lap 32: Heidfeld is down from first to fourth after his second stop.
