Welcome to LIVE coverage of the Singapore GP from the spectacular floodlit Marina Bay circuit!

Hulkenberg is told to give a place back to Perez after overtaking him in that massive ding dong. Hulkenberg's reaction: "WHAT?! FOR WHAT?!" Not happy.

Vettel's lead is eight seconds ahead of Nico Rosberg, and you feel he could extend that whenever he and his team wish.

Lewis Hamilton is on medium 'prime' tyres and is told he must go four laps further on this set.

Vettel pits... and comes out well ahead of Nico Rosberg. Not even close, and the German remains well clear.

Massa comes out of the pits behind Lewis Hamilton! The Brit has leapfrogged the Brazilian and is into sixth.

Three abreast! Maldonado, Perez and Hulkenberg! Three cars pile in where there's space for just one, but somehow they avoid major contact!

Ah, there's Tom Jones on the pit wall. He looks bored. Maybe if he faced away from the action and only turned round when he heard a car he really liked?

Hamilton has risen to P5, but only because of pit stops. Mercedes tell him his pace is good.

Webber, Button and Hulkenberg all come down the pit lane... and Webber rejoins right behind the Toro Rosso of Daniel Ricciardo.

Massa pits now - medium compound tyres for him.

Raikkonen, incidentally, came out of the pits in 19th place which was a decent result because he has found a clear stretch of track.

Lock-up for Lewis Hamilton as he pursues Felipe Massa. He runs a little wide before coming back onto the track, but that has cost him time and tyres.

Here comes Gutierrez whose Sauber is fitted up with some super-softs.

So Kimi Raikkonen is clearly on a three-stopper, but he is still the only man to have come into the pits.

Kimi Raikkonen is the first man into the pits on lap 11 - the stop is a brisk 3.5 seconds, with his entire pit lane visit lasting 29.4 seconds.

Webber is over two seconds behind Fernando Alonso, with Grosjean just eight tenths behind the Australian. Considering Vettel's pace, this is puzzling.

There's a bit of a queue forming behind Mark Webber, who has dropped back behind Fernando Alonso. This, of course, helps Vettel even more.

Depending on whether teams opt for two- or three-stop strategies, we should start to see cars coming in for new tyres from about lap 11 or 12 - certainly those that started on super-softs.

Lewis Hamilton and Jenson Button are in seventh and eighth, and unless you're Fernando Alonso the overtaking opportunities really are difficult to come by around this track.

Vettel's pit radio instruction is to look after his tyres. Small wonder given the astonishing pace he has set at the start of this race.

Kimi Raikkonen is up to 11th place - the Finn started 13th on the grid.
