Lewis Hamilton is fastest of all in the first sector but backs off after being given little room when trying to pass his team-mate Nico Rosberg at Turn 7.

Daniel Ricciardo: "Inters are the way to go I reckon."

Nico Rosberg nudges down Sebastian Vettel with a 1:51.066 while Daniel Ricciardo is sixth fastest, ahead of Daniil Kvyat and Marcus Ericsson. No time yet for Romain Grosjean, Valtteri Bottas (pictured) and Felipe Massa with three minutes to go.

The inters look to be quicker and Valtteri Bottas opts out of his lap to make the switch to them. Lewis Hamilton, on the inters, is fastest with 1:49.834 ahead of Sebastian Vettel but impressive work from rookie Max Verstappen, third with 1:52.896 with his first experience of a grand prix weekend in the wet.

Out lap done for Valtteri Bottas and he embarks on a timed lap on the full wets.

The green light is on at the end of the pit lane and out head the 10 cars for these final 12 minutes. Sebastian Vettel and Lewis Hamilton are on intermediate tyres.

"If you go straight at it on the Inter tyres there is always a risk you can make a mistake."

Brian Pigott: You may as well say when it rains F1 completely stops. This never happened in the '90s this ruins F1 - shame.

The session will definitely resume at 10:15 GMT and both Williams head down to the end of the pit lane on full wets.

This delay means a lot of hanging about for the drivers. Some prefer to remain in their cars...

...others opt to stretch their legs and go for a wander. Four minutes to go, all being well.

BBC weatherman Ian Fergusson: 1803 local: Rain showing clear signs of fading away now, so a more positive outlook. Track temp now 38.8C.

Kimi Raikkonen, who qualified 11th: "We got it wrong. We should have been out earlier but that is how it is. The lap time is there or thereabouts so we expected to be strong in qualifying. We finally find some speed and this happens, that's part of the game but it is disappointing."

A reminder that Will Stevens failed to get out in qualifying, while his Manor team-mate Roberto Merhi failed to get within 107% of the best time in Q1, meaning it will be down to the stewards to determine if they can race on Sunday. Another race where the full field does not start on the cards?

Mr Rae: I don't share Alonso or Button's faith that the car will come good! It's not good enough, it really isn't!

Adam Swinden: Despite what he says, Alonso has got to be regretting his move to McLaren with a qualifying performance like that.

"The light levels will begin to drop - and they don't want it to be too dangerous."

Race controls confirms that the earliest qualifying will get resume is at 10:15 GMT. That's 18:00 in Malaysia, meaning the light will increasingly become a factor.

The safety car is deployed to check the track conditions. It is kicking up a lot of spray, but it still very warm and not much rain at the moment means it should start drying pretty quickly.
