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

So Sebastian Vettel moves cloer to another world championship, but that great performance from Alonso means the damage is limited to just five points. Still, there will surely be no catching Sebastian Vettel in 2013. Thanks for joining us this weekend.

Mark Webber gets a ride home on the flank of Fernando Alonso's Ferrari. That's nice of him...

Brilliant, brilliant drives from Fernando Alonso in second and Kimi Raikkonen in third. Rosberg and Hamilton come fourth and fifth, Massa sixth and Button struggles in seventh.

SEBASTIAN VETTEL WINS THE SINGAPORE GP! A masterful drive from the world champion!

Webber's Red Bull is on fire! He will not finish!

Webber has an engine problem, is short-shifting and is just limping to the end - Felipe Massa whizzes by...

And Hamilton is past Webber, a sitting duck. The Aussie down to P6 as Vettel starts his final lap.

Here we go - Rosberg passes Webber, who can do absolutely nothing. A dramatic difference in pace.

Webber is going backwards in fourth place - Rosberg could very easily catch and pass him by the end.

Button is going backwards - he has been passed in double-quick time by Rosberg, Hamilton and Massa. Webber being told to nurse his car to the end.

Hamilton finally makes it past Perez, who is now in the sights of Massa - the two McLarens really falling away now.

Rosberg past Perez, but as the Mexican holds Hamilton up Massa joins the fray! What a finish!

The two Mercedes are all over the back of Perez, and Hamilton has a go at Rosberg! No way through this time!

What a disaster for Paul Di Resta, who has gone into the wall in the final stages of a brilliant drive, his third DNF in a row. And it doesn't look like there will be a safety car, which is great news as this is shaping up to be a brilliant finish.

Both Mercedes go past Hulkenberg, and Di Resta has crashed!

Raikkonen, what a move! He goes down the outside of Button, narrowly avoids gettting stuffed into a wall and makes it into third! Terrific driving.

Webber overtakes Hulkenberg and takes P6 - next stop, Sergio Perez!

Raikkonen lines Button up in the DRS zone, but there's just no way through!

Webber is right on the back wheel of Hulkenberg - it's all very well being faster, but now he has to find a way past.

Webber has gained six seconds in two laps on Nico Hulkenberg, and we are starting to see the benefit of being on fresher rubber.
