* Lap 1: On pole position for the second time in his career – but the first since Imola 2004 – Jenson Button is swamped by the Renaults at the start. Giancarlo Fisichella grabs the initiative from world championship-leading team-mate Fernando Alonso. Button takes third while Michael Schumacher (who is making only his second front-row start of the season – he’s not managed it since Bahrain) is engulfed by the McLarens and slips so sixth, behind Juan Pablo Montoya (who edges the German towards the grass at Turn One) and Kimi Räikkönen. Jarno Trulli takes seventh after forcing Takuma Sato into a grassy mistake, but the Japanese resumes in eighth ahead of Felipe Massa, Nick Heidfeld, David Coulthard, Ralf Schumacher, Jacques Villeneuve (down from eighth on the grid), Mark Webber, Christian Klien, Christijan Albers, Patrick Friesacher, Narain Karthikeyan, Rubens Barrichello (who started from the pits, after being condemned to the back of the grid with a gearbox problem yesterday) and Tiago Monteiro. Fisichella leads Alonso by 0.7s at the end of the lap, with Button another 0.7s adrift.

* Lap 2: Ralf Schumacher passes Coulthard at the hairpin. Barrichello overhauls Friesacher. Villeneuve pits for a fresh nose and slips to the tail of the field. Fisichella leads by 1.1s.

* Lap 5: Alonso sets fastest lap for the first time – 1m 15.984s. The gap is 1.0s.

* Lap 6: Alonso laps in 1m 15.935s.

* Lap 7: Fisichella responds: 1m 15.455s.

* Lap 8: Karthikeyan spins at Turn Two and drops behind Monteiro. Barrichello moves up to 15th after passing Albers.

* Lap 12: Michael Schumacher is the first leading runner to pit. He drops to 12th.

* Lap 13: Fisichella laps in 1m 15.135as – his best yet.

* Lap 15: Button and Ralf Schumacher pit.

* Lap 16: Sato and Albers come in.

* Lap 21: Massa, Heidfeld and Klien pit.

* Lap 22: Karthikeyan refuels; Sato retires to the pits.

* Lap 23: Trulli pits. Räikkönen laps in 1m 14.384s. Alonso wags a finger at Klien after being held up while lapping him.
 
* Lap 24: Alonso and Räikkönen pit. They resume in the same order. Karthikeyan clips the wall at Turn Four and retires to the pits.

* Lap 25: Fisichella – a quick stop – and Montoya come in. Montoya rejoins inches ahead of Alonso at the start of his 26th lap, but then runs onto the grass and slips back to third.

* Lap 26: Webber pits.

* Lap 30: Webber slips from ninth to 12th after running wide at the hairpin.

* Lap 31: Barrichello pits.

* Lap 32: Fisichella leads Alonso by little more than a second. Montoya, Räikkönen, Button, Webber, Trulli, Alonso, Heidfeld, Ralf Schumacher, Webber, Coulthard, Klien, Monteiro, Albers and Friesacher complete the order.

* Lap 33: Fisichella slows and retires to the pits. Alonso leads by a couple of seconds from Montoya.

* Lap 34: Button and Michael Schumacher make their second stops.

* Lap 35: Alonso begins to edge away from Montoya.

* Lap 39: Alonso clips the wall at Turn Four and crawls back to the pits. Montoya leads. Friesacher retires.

* Lap 40: Montoya is several seconds clear of Räikkönen, with Button, Michael Schumacher, Trulli, Massa, Heidfeld, Ralf Schumacher, Webber, Barrichello, Coulthard and the lapped Klien, Villeneuve, Monteiro and Albers trailing behind.

* Lap 44: Heidfeld’s engine expires in a cloud of smoke.

* Lap 45: Ralf Schumacher makes his final stop.

* Lap 46: Räikkönen has reduced Montoya’s lead to 2.6s.

* Lap 47: Sato rejoins; Button retires after crashing at the final chicane. The Safety Car is deployed.

* Lap 48: Everybody pits bar Montoya and the recently-refuelled Ralf Schumacher.

* Lap 49: Montoya pits. He rejoins behind Räikkönen – but jumps a red light at the pit exit in the process.

* Lap 51: Race restarts, with Räikkönen ahead of Montoya, Michael Schumacher, Trulli, Barrichello, Massa and Webber (tied together), Ralf Schumacher, Coulthard, Klien, Villeneuve, Monteiro and Albers (oh yes, and Sato’s still running).

* Lap 52: Montoya receives the black flag for his pit indiscretion.

* Lap 55: Räikkönen leads Michael Schumacher by 2.6s – but the gap is fairly stable.

* Lap 62: Trulli suffers a technical failure approaching the final chicane. He misses the corner and pulls off to retire shortly afterwards.

* Lap 65: The gap between the leaders comes down to 1.6s,
 
* Lap 66: Sato – not on his 66th lap, although many of the others are – spins into retirement at Turn 10.

* Lap 67: Michael Schumacher closes to within 1.5s.

* Lap 68: Traffic helps Räikkönen extend his lead to 1.9s.

* Lap 69: It is back down to 1.3s.

* Lap 70: Räikkönen wins by 1.1s from Michael Schumacher, Barrichello, Massa, Webber and the lapped Ralf Schumacher, Coulthard, Klien, Villeneuve, Monteiro and Albers. Webber’s last-lap dive at the final corner comes to nothing. It is Ferrari’s first double podium of the season – and the first time neither Renault has scored.
