Lap 74: Ralf Schumacher is forced out in the closing stages with smoke coming from his Williams.
Lap 73: It's hard to see how Button can get past. It will take a mistake from the Italian you feel.
Lap 72: Button is really putting the pressure on Trulli. Will he crack?
Lap 71: It's less than two seconds now. Can Button find a way through?
Lap 70: It's just 2.2 seconds between the first two. Still Button faces a tough task to get past on this street circuit.
Lap 69: The gap is down to 3.5 seconds now. Button is really come up behind Trulli's exhaust.

Lap 65: Trulli's lead is holding steady at the moment. Ten runners remain with little sign of any positional changes at present.
Lap 64: No change at the front.
Lap 63: Montoya moves over to let Button through. The gap to Trulli is now under five seconds.

Lap 48: Schumacher throws his helmet in disgust. He's fuming with Montoya.
Lap 47: Trulli is now back in front and sure enough Schumacher is out. He was nudged by Montoya in the tunnel the replays show.
Lap 46: The race restarts. But as soon as it does, Schumacher comes out of the tunnel with his left front wheel hanging off! He's surely out of the race and won't win for the first time this season.
Lap 45: The safety car is still out.
Lap 44: Alonso is fuming with Ralf Schumacher after that incident. The Spaniard tried to go round him on the outside in the tunnel but it was simply too much to ask and he smashed into the wall. He's OK though.
Lap 43: Button takes the opportunity to make a second pit stop. Trulli also comes in so Schumacher takes the lead.

Lap 41: Button is also closing the gap on Schumacher slightly.
Lap 40: Alonso is closing a little on Trulli. The gap is now 2.1 seconds.
Lap 39: Ralf Schumacher pits from ninth - could be a gear problem. Meanwhile, the leaders reach half distance.
Lap 38: Button trails Schumacher by just over three seconds. The Briton is fourth at present.

Lap 35: Towards the rear, Ralf Schumacher is struggling with some sort of problem.
Lap 34: A reminder that Trulli leads from Alonso, then it's Schumacher and Briton Button is fourth.

Lap 32: Button is nine seconds off the lead, but he's got traffic to deal with now.

Lap 30: Raikkonen retires with engine trouble making it another miserable weekend for McLaren. Montoya has gone past Heidfeld to move into what is now seventh place.
Lap 29: Trulli still ahead of team-mate Alonso.

Lap 25: Trulli pits from the front. It's an 8.5 second stop. He's back out in third, ahead of Button.

Lap 23: Button is being held up by Cristiano Da Matta.
Lap 22: Massa stops for fuel. That lifts Heidfeld into eighth spot.

Lap 19: Button comes in for his first pit stop. He's out after 9.5 seconds. Gianmaria Bruni is also in.
Lap 18: Trulli is coming up behind the Minardis and that should help Schumacher and co close the gap to the leader.
Lap 17: Schumacher is now challenging Kimi Raikkonen for fourth. He'll be desperate to get past the Finn and start chasing Button and the Renaults.
Lap 16: Trulli still leads the way and he's extended the gap at the front to more than two seconds. Pantano's pit session didn't work. Smoke is coming out his car and his race is over.
Lap 15: Giorgio Pantano of Jordan is the next to pit.
Lap 14: Montoya comes into the pits to refuel. He drops out of the points positions.
Lap 13: Webber is in trouble and he's crawled to a stop. That's a blow for Jaguar as he'd been in the points.
Lap 12: At the front, Trulli's lead from his team-mate is just over a second. He's just set the fastest lap.

Lap 6: The safety car is still rolling around.
Lap 5: Juan Pablo Montoya and Mark Webber are into the points now, but for how long remains to be seen with confusion reigning at present.
Lap 4: Sato's engine blowing up has caused all sorts of trouble. Several cars need to pit.
Lap 3: The front three already have a good gap with Sato holding up the chasing pack. And sure enough Sato's car expires with so much smoke coming out that is causes a crash, with Giancarlo Fisichella's car flipping over. The race is halted. David Coulthard was hit by Fisichella and his back end is badly damaged. The safety car is out. Coulthard won't be able to continue.
Lap 2: There looks like some kind of smoke coming from Sato's BAR car.
Lap 1: Takuma Sato has flown up to fourth from seventh after that thrilling start. The Renaults are at the front though. Christian Klien goes into the barrier at the hairpin.
Start 2: Off they go for real this time. Fernando Alonso surges past Jenson Button into second as Jarno Trulli keeps his lead. Michael Schumahcer drops back to sixth.
Warm-up lap 2: The cars are off again on a second formation lap after that problem with Panis' car. But would you believe it, Panis' Toyota immediately stalls for a second time. He's now being pushed off the grid.
Start: Olivier Panis is not in the correct grid position and team mechanics rush back on to the grid. The start will have to be delayed. Covers are going back on the tyres as it is announced the race will now get under way at 1309 BST.
Warm-up lap: The cars roll off the grid to get their tyres heated up.
Pre-race: The stars are out in force for the highlight of the F1 season. The likes of Brad Pitt, Matt Damon and Roman Abramovich are just being cleared off the grid ahead of the warm-up lap.
