LIVE coverage of the F1 Malaysian Grand Prix - race begins at 9:00am GMT on Sunday.

There was a clash between Raikkonen and Magnussen on the second lap, which is being investigated; and added to that Bianchi has a stop-go penalty for spinning Maldonado off at the start.

He's still comfortably leading, though, so the tyres should be reasonably fine for the time being.

Hamilton's been told on the team radio that Rosberg is struggling with his rear tyres, so "make sure you look after them".

Interesting little duel between Magnussen and Massa in eighth and ninth at the moment, swapping places.

Raikkonen has a new tyre but he's going to be way back in the field now, obviously.

This battle between team-mates Vettel and Ricciardo is going to prove fascinating, not just today but potentially for the rest of the season.

Kimi Raikkonen has a problem with his rear tyre, and is chugging along in his Ferrari in a desperate attempt to get back to the pit.

That's a two second lead for Hamilton at the end of the first lap.

Rosberg wobbles on Turn 3 but recovers, and Hamilton is stretching his lead out already.

A dramatic start! Hamilton leads as Rosberg squeezes past Vettel at the start and Ricciardo takes the place of his team-mate in third!

Here we go!

The formation lap is in progress. We're counting down to the start now.

Force India's Sergio Perez is out of his car and divesting himself of his gear - he finishes before he even begins the day due to that car problem. Disappointing for him.

A lot of chat about tyres in this heat - a lack of grip on the track makes the use of hard tyres unlikely, and a three-stop strategy quite possible.

If you're a fan of Sherlock, apparently Benedict Cumberbatch will be presenting on the podium later. I suspect that he won't be wearing one of those very long coats in this heat.

There's a minute's silence now in honour of missing plane MH370.

Force India's Sergio Perez has stalled in the pit lane - the mechanics have to go out to retrieve him and drag him back.

If you're in the UK, you'll be suffering due to the disappearance of one hour's sleep overnight - but you'll also likely have strong opinions about Lewis Hamilton equalling Jim Clark's record for most pole positions by a British driver. Hamilton starts at the front of the grid in his Mercedes this morning. Sebastian Vettel sits alongside Hamilton, with Nico Rosberg in third.

Just under half an hour to go until the start, and for those of you wanting to know whether yesterday's thundery and very, very wet conditions are replicated on track today - well, not yet. Looks fine and extremely warm.

Good morning, and welcome to our LIVE coverage of the Malaysian Grand Prix!
