Welcome to our LIVE coverage of qualifying for the Malaysian Grand Prix at Sepang.

Ferrari's decision to try intermediates now looks insane - Raikkonen is coming back in, and Alonso has collided with Kvyat! Madness!

Q2 gets under way, and the rain is falling a little more heavily right now...

Strangely, Kimi Raikkonen has the intermediates on - bit of a gamble, could it pay off?

Rosberg comes out of the pits to queue up ready for Q2 - and he has full wet tyres on. Just goes to show how much rain is still falling.

Q2 begins in just a few minutes' time.

Marcus Ericsson brings €11 million in sponsorship to Caterham - they'll have to spend most of that in recovery lorry fees from the looks of things so far this season...

No big surprises in Q1 then - the two Mercedes are quickest, Vettel next best, and all the big names safely into Q2.

Between Ericcson's crash and Vettel running wide on turn nine to go off the track briefly, it just shows how much on the edge these guys are on the edge - and never more so than when it's wet.

A replay shows Ericsson's crash - one of his tyres touched a kerb into turn three, and sends him flying down the track totally out of control, and into the track sidewall. He came close to taking out Esteban Gutierrez as well!

Just 35 seconds left on the clock - so the session is efffectively over since it's impossible to get from pits to start line in the time left...

BIG SMASH! It's Marcus Erisccon's Caterham that lies in pieces, and the session is instantly red-flagged as he comes to a halt across the middle of the track!

Vettel loses it slightly on his second flying lap - and he'll come back in, nothing more he can do in this session now.

That rain is still spotting - and it's slippery out there, with Max Chilton full-on rallying his way round. Not that it's helping him - he's 21st right now.

Vettel produces the goods - a 1:57.654, that makes him the only man within half a second of the Mercedes, both of whom are back in the pits chilling out and waiting for Q2.

Hulkenberg third quickest now - but still 1.7 behind the two McLarens.

Vettel is back out on track now - he's 10th so should be safely into Q2.

Button blasting up the start-finish straight... and he's 15th! Just about out of that bottom six - and outshone by Magnusson, who makes it into 12th.

Hamilton up to within 0.019 of Rosberg now - still nobody close to the Merc duo. Anyone else got a feeling we'll still be saying that come the end of the season?

The rain is expected to continue throughout the rest of this Q1 session - Magnusson has climbed to 14th, but Button is still down in 19th. He's got it all to do.

Button and Magnusson are back out for flying laps on their intermediates now - but it's just started raining a bit harder, and they'll both have a job to get out of Q1 from the looks of things...

VETTEL INTO THE PITS! The champ has yet another technical problem and he's had to come in. More as we get it on that...
