Good morning everyone, and welcome to race day. It's the second GP of the season, from Sepang, Malaysia.

The race leader is Sergio Perez, who opted to stay out. Hamilton went a touch beyond his mark - correction, he didn't stall, but he couldn't be released when other cars were coming down the pit lane.

Button-watch... HAMILTON STALLS!

Raikkonen and Kobayashi also went in, so they'll be ones to watch. Schumacher wants to come in next, and here goes Hamilton!

Webber passed by Vettel - but gets him at the next corner! Good duel by the Red Bull pair - which of them will stop first?

Button straight into the pits - so's Rosberg.

WE'RE RACING!

If everyone wants to make an early tyre change, which of the McLaren drivers will get to go first?

Drive-through penalty for de la Rosa confirmed.

THE SAFETY CAR IS COMING IN THIS LAP!

Through we go into lap 13, no safety car. Rosberg says he wants to go to inters when the safety car comes in.

The top 10 as it stands: Hamilton, Button, Perez, Webber, Alonso, Vettel, Vergne, Massa, Rosberg, Karthikeyan

Still behind the safety car, but the noises from the drivers are that conditions are alright for racing. We could be back in the thick of it very soon.

It's been another poor start for Mercedes - Rosberg in 9th, Schumacher in 15th after his early spin - there's room for improvement there.

The stewards are investigated HRT personnel still being on the grid at the restart. That could mean a drive-through penalty for Pedro de la Rosa.

Through one lap, and no chance of the restart quite yet. Forecast for the rest of the race is for no more rain, Button told.

Onboard cameras showing that visibility is still poor. It looks far better from above than it does behind the wheel. But it is improving.

There's plenty of spray coming up right away, but it's a big improvement on the conditions when the race was suspended.

GO GO GO! (Behind the safety car)

As we resume, why not join me on Twitter and tweet me @Mark_Eurosport your thoughts and predictions?

Not long now. Discussion already being heard with Nico Rosberg over the radio about when to switch to intermediates.

Drivers back in the cars, plenty of feverish activity as the race preapres to resume. There are just spots of rain now - that's no great problem - it's the standing water which is the key issue now.
