Welcome to live coverage of first practice for the Singapore Grand Prix.

We'll be back with coverage of second practice from 14:30 UK time.

Webber then fastest in the opening session from Schumacher, Sutil, Vettel, Alguersuari, Button, Liuzzi, Buemi, Kubica and Petrov. Outside the top 10 are Hamilton (18th) and Massa (19th).

Sutil second after his last effort while Webber, despite locking up, pushes him into third and Schumi second with 1:54.589 for top spot.

Schumacher's final lap of a long, hard run for him is 1:54.708 and enough for P1.

The chequered flag comes out and Hamilton crosses the line soon after with a time for 10th.

Vettel takes top spot with 1:55.137 moments after Button had leapt up despite finding traffic.

Hamilton cannily comes through the pitlane to find a clear part of the track to work with.

Webber finally finds a clean lap sans traffic and the result is 1:56.831 and fifth.

Sutil with 1:56.226 to go above Button.

Sutil second as a flurry of quick laps are set. Webber has to back off...

Schumi with 1:57.757 for P2 before Button tops the pile with 1:56.228.

Button goes third with 1:57.872.

Vettel with a first effort of 2:07.594 while Lewis sets 2:02.454 to go 12th.

Button is 10th quickest but the others are yet to set a flying lap.

And all four cars are indeed now on track.

The Red Bulls and McLarens yet to come out, but surely they will do soon.

Alguersuari pits.

Alguersuari third now with 1:58.974... and goes second above Schumacher with 1:57.904 on his next lap.

Alonso out on hard slicks while the city is now in darkness.

Kobayashi's latest 1:57.260 fastest of 15 drivers to have set a time. Massa up to third while his Ferrari team-mate Fernando Alonso waits in the cockpit and will be out soon.
