The loser this weekend is Hamilton - Vettel and Alonso take advantage. And what a result for di Resta in fourth!
And Marussia come through for the biggest result in their F1 history - 12th via Glock. Great effort.
Button second, then Alonso, Di Resta, Rosberg, Raikkonen, Grosjean, Massa, Ricciardo, Webber round out the points.
VETTEL WINS THE SINGAPORE GP!
Time up in this race - the chequered flag is coming...
SENNA IS OUT! Two technical retirements for Williams - that's a disappointing afternoon for the team, who were competitive on pace.
Senna, meanwhile, is complaining of a loss of power, and he's drifted down to 12th place. Glock is running 13th - if he takes 12th it will be a huge result for Marussia.
Webber stuck behind Ricciardo in any case - his tyres not giving him enough of an advantage to get ahead of the Toro Rosso.
Webber and Kobayashi's incident will now be investigated after the race.
Alonso settled in third, about eight seconds behind Button. The battles for position appear to be further down the field.
Webber already up close and personal with Ricciardo's Toro Rosso - if he can maintain this pace, Massa, Grosjean and even Raikkonen are not far up the road.
Vettel appears to have settled this contest, now about four seconds clear of Button.
Webber's got him, however - and not far up the road is Daniel Ricciardo, and Webber has the fresher tyres.
Webber, who was right in the thick of the championship mix a couple of races ago, is now scrapping for a single point against Senna.
Top 10 with 10 minutes to race: Vettel, Button, Alonso, Di Resta, Rosberg, Raikkonen, Grosjean, Massa, Ricciardo, Senna.
Alonso's tyres are four laps older than Di Resta's - Force India quietly optimistic they can get the better of the Spaniard here.
It's the measure we'll stick to as well - as it stands, Alonso would have a 29-point lead in the championship over Vettel, while Raikkonen would rise to third without a race win to his name this season.
For the first time the telemetry shows the time remaining rather than the laps remaining. 12 minutes to go in Singapore.
Paul di Resta is about 2.5 seconds down on Alonso, who appears for his part to have stepped up his pace.
No action taken on the Senna/Massa move - but Webber's pass on Kobayashi is the subject of investigation now.
Yes - tyre change for Hulkenberg. Di Resta, by contrast, is closing up on Alonso for third!
Looks like a new front wing for Kobayashi, and supersoft tyres while he's there - while Hulkenberg may have suffered a tyre problem.
Now Kobayashi damaged in that same battle! Webber had just got past him running through white lines off the side of the track to do it, then Kobayashi clips Hulkenberg - very messy.
Perez clipped! He tries to pass Hulkenberg and not only does he not get the position, but he sustains a bit of front wing damage to boot.
That recording may have been from a bit earlier, because that would take us to the end of the race!
McLaren's prediction is 12 laps until the end of the race. It's a straight fight with Vettel, Button is told.
The flag will be shown when there's one lap to go - so the drivers will see the chequered flag, whatever lap it eventually comes on, after two hours of racing.
Alonso, for his part, appears to have backed off. And why wouldn't he? He's a master strategist and knows emerging third today will do his title campaign no harm at all.
A bit more on Hamilton's exit from the race.
Senna didn't care for that move from Massa - he felt his compatriot had to cut the chicane to make it stick. Massa would probably argue that Senna pushed him up against the wall. Not sure we'll see any action taken.
No tyre difference between Button and Vettel, and neither driver should have to stop between now and the end of the race.
1:53.152 from Vettel, who is keeping himself out of trouble at the front of the race now.
Vettel with the lap of a champion - fastest lap of the race to stretch out to a two-second advantage. Just what he needed.
Looks like the Massa/Senna incident is going to be reviewed by the stewards.
Someone having a big race lower down is Kovalainen - running 12th, and could yet score a best-ever finish for Caterham.
If Button can keep pace with Vettel, he will be able to open DRS shortly. There's still life in this race, and 24 minutes on the clock.
Vettel 1.3 seconds clear of Button, who has 2.2 seconds on Alonso in third.
That was quite majestic from Massa - he rode his luck and got the place he deserved.
Massa and Senna touch! Looks sure to be a big incident but somehow Massa keeps control AND takes the position.
No DRS for a couple of laps until the resumption - it's Vettel, Button, Alonso, Di Resta, Rosberg, Grosjean, Raikkonen, Ricciardo, Senna, Massa in the top 10.
Vettel gets away cleanly this time - all very simple.
Button was not happy with Vettel's braking at the restart - and complained to his team. He's going to be very watchful when the two restart again at the end of this lap - the safety car is back in.
The Schumacher/Vergne crash will be investigated by the stewards after the race. Looks like Schumacher had lost control by the time he hurtled into the back of the Toro Rosso - not sure whether he was entirely to blame.
Petrov's race seems to be over - he doesn't make it the whole way down the pit lane after that stop.
Stops for Hulkenberg, Perez, Petrov and de la Rosa as well.
Webber plumps for a change of tyres - it's another gamble in race that's quickly becoming a bit of a strategy headache.
Schumacher puts an arm around Vergne as both men walk away - looks as if the German was apologising for his role in the shunt.
SAFETY CAR BACK OUT.
Schumacher locked his front tyres, and collected Vergne as they battled for 11th. Vergne was in front, but both men are unhurt.
CRASH! SCHUMACHER HITS VERGNE! BOTH OUT!
Webber harries Hulkenberg - but he cannot get around the outside of the German in the first few corners.
WE'RE RACING AGAIN!
Button very nearly into the back of Vettel! The German testing the brakes as Button warmed up the tyres. They don't touch, but it was mighty close.
The safety car coming in at the end of the lap.
Force India, with di Resta and Hulkenberg in 4th and 5th, positioned really well for this race and some big points.
Most drivers on fresh rubber, coming in when the safety car was called into action. All cars fueled to last the race, and these slow laps should mean they have a bit in reserve.
This race is now does not have 24 laps remaining - it's a 40-minute race, with the two-hour cut-off time looming. They won't complete the remainder of the race in time. What are the tactical implications?
Strike that - this time Maldonado does come in to end his race, which promotes Jean-Eric Vergne into the top 10.
Top 10 as it stands: Vettel, Button, Alonso, di Resta, Hulkenberg, Webber, Perez, Rosberg, Grosjean, Maldonado
Still a little debris from Karthikeyan's car, but nothing that should prevent us from racing imminently.
Safety car coming to an end - the lapped cars are now allowed to pass the leaders. Maldonado did not come in to retire the car when he could have done.
From bad to worse - he has a hydraulic issue, he's told over the radio - he's going to have to retire the car.
It doesn't appear to have worked for Maldonado at all - he's down in 10th. No great advantage over his rivals, either, in terms of tyre freshness.
Williams make a switch! Maldonado went to soft tyres. That means behind the safety car the order is: Vettel, Button, Alonso, di Resta, Hulkenberg and Webber.
Marbles very visible on the track around the final turns. Tyre degradation so high here in Singapore.
Lots of stops - Di Resta, Rosberg and Grosjean all into the pits, trying to make the most of the safety car.
Karthikeyan just went too wide into turn 18, and came to grief. Safety car was inevitable as they clear the car away. Unsurprisingly, Vettel and Button make their stops.
Raikkonen sweeps into the pits at pace - and the SAFETY CAR IS OUT.
YELLOW FLAGS - Karthikeyan has crashed!
Alonso now steps out to have a look down the outside of Maldonado. The Venezuelan resists, but it's tense.
Rosberg in fourth is at the head of this Grosjean, Maldonado, Alonso battle. Less than two seconds between the four of them.
Vettel and Button, meanwhile, staying about three seconds apart. All under control for the German.
Supersofts could have helped Maldonado in open air, but this is not the ideal situation for him.
Maldonado out in sixth right behind Grosjean on old rubber - Alonso on his rear wing. This is a moment where the Spaniard could pounce.
Fastest lap of the race comes from an unlikely source - Vergne in the Toro Rosso posts 1:53.510.
Alonso and Maldonado in - the Spaniard opts for softs, while Maldonado goes for supersofts.
An hour into the race in Singapore, and we're not halfway through the race. It looks like we're not going to see a completed race at this rate - the cut-off is two hours.
Webber pits from seventh - he comes out in 11th place.
Button, who has just set his fastest lap of the race so far, told he can make a stop as and when. McLaren can sink all their efforts into his GP for the rest of the day.
Cloudy in Singapore tonight - but still hot - temperature around 29C.
Vergne emerges after his latest stop, getting straight past Kovalainen on the track.
Perez is right on the back of Ricciardo, and needs to get by quick to avoid losing precious time down in 13th.
Not a lot of action on track at the minute, but nor is it long before the next flurry of pit stops. And there's plenty at stake here with not a lot separating the top four.
Another pit stop for Senna before we reach halfway - smooth enough, but interestingly he's taken super soft tyres. It's a gamble, but when he's running in 12th, they can afford to experiment.
Vettel's lead on Button worth around three seconds - Maldonado 1.7s down on the Brit, while only 1.3s ahead of Alonso.
Either way, Hamilton looks bitterly disappointed. And he's got to watch as his rivals fight for the big points.
The team tells Hamilton they "did everything they could yesterday" - that points to an existing problem for the race leader.
Maldonado heading towards a podium finish now, and Raikkonen into a points finish.
Vettel assumes the lead of the race, and Button into second. Nothing Hamilton could have done differently - his car simply gave up on him.
What a disaster for Hamilton, who looked set to close the gap from second in the championship to Alonso. Instead, after this retirement, he may be the big loser today, and his title hopes may almost evaporate with it.
HAMILTON OUT! He's got a technical problem, he's stuck in neutral, and he's heading out of this GP!
Massa now the quickest man on track with a 1:54.481 - the men with open track are making the best progress, and Massa has plenty f clear air afte ra second stop.
Alonso starting to motor now - he's lapping around a second quicker than race leader Hamilton. Still down in fifth, however.
Senna, running in 12th, joins the back of the battle between Schumacher and Raikkonen. Kimi has been patient so far, but now has problems in front and behind him.
Hulkenberg and Perez have both finally pitted - they rejoined 14th and 16th - much will depend if they can save a stop on their rivals.
Hamilton just stretches the lead back out a touch to two seconds. Every little helps the Brit as he aims to win a second straight race.
It's a very tough race physically - the humidity extremely high, and the drivers take more fluids on board here than anywhere else on the calendar. It will get harder to maintain concentration for the drivers in the latter stages.
Button is sitting a steady 3 seconds behind the battle for the lead in third, with Maldonado a futher four adrift.
Hamilton's lead now 1.7 seconds. If that dwindles to less than a second, Vettel can open DRS and give himself an excellent chance of passing with an overtaking boost.
Hulkenberg has to allow di Resta through as another man struggles on the first set of tyres. Will they reap the rewards later?
Perez fails to turn in at turn 10 - those tyres really ailing now, and he will surely have to pit.
Massa, having a stinker of a race, crawling slowly back up the field. He's now 18th.
Vettel has taken time out of Hamilton on each of the last three laps, the gap now just under two seconds.
Alonso now within range of Hulkenberg and is syeing a DRS pass.
Every driver in the top 10 now on soft tyres, so no advantage there. Vettel closing right up to Hamilton, but the tyres are a couple of laps older.
Alonso now ahead of Perez, who's continuing on his original set of tyres - that's the Sauber way, milk those tyres for all they're worth...
Maldonado! Survives a scare as he loses the back of the car opening DRS, but holds on AND gets ahead of Hulkenberg to reclaim fourth.
BUTTON BEHIND VETTEL!
In he comes... Slick stop...
Maldonado emerged behind Vettel, Hamilton ahead. The eyes are all on Button,who may come in this lap.
Fastest lap from Vettel - 1:55.495 - the pressure building.
Vettel ahead of Raikkonen - he's flying! Has Button made the right call - he stays out, Maldonado pits.
Maldonado has now climbed back into second place by virtue of those stops.
Vettel going pretty well - already up to sixth thanks in part to the pit stop reshuffle and having passed Perez - next up is Raikkonen.
Looks as if Hamilton is also now coming in - that will hand Button the lead for the time being, and he is the man of the moment on track.
Alonso the latest to make his stop - he's been telling the team over the radio that the tyres have been degrading rapidly. He's been going nowhere fast today.
Vettel into 12th, in the thick of a big battle for track position. Vettel on three stops could come through the field fast later, but it looks like the early advantage very much with Button in their private battle.
In comes Vettel - is this a two-stopper for Vettel? It's an early move if so, but his pace was compromised.
Senna swarming all over the back of Daniel Ricciardo now - he's having his own little battle some way down the field in 15th place.
2.3 seconds the gap between Vettel and Button now - will he look to pass on the track or is he about to make a stop?
Button really on the move now - he pulled back 1.9 seconds in the last lap alone on Vettel.
Soft tyres for Webber - he's 20th for now, one place ahead of Pic.
Webber first of the top men into the pits, coming in from seventh - can he find a decent pocket of space on the track to gain some time?
"@Mark_Eurosport Hamilton 1st, Alonso 2nd, Vettel 3rd, Button 4th and Maldonado 5th. #F1 #SingaporeGrandPrix" predicts Drean Steenberg on Twitter. Anyone disagree?
'Felipe - you're pushing too hard and destroying the tyres' - that's a disheartening message for the man right at the back of the field.
Webber pushing hard for a way past di Resta, but apart from that thigns are fairly static in the top 10.
Button just starting to pick up his pace after a slow start. The gap to Vettel no longer increasing.
Common sense prevails - no action taken for the drivers who took the escape road - they had little other option.
Massa has a new target - go for a longer stop, he's told - 16 laps longer than planned.
Mercedes, as we've seen on a few occasions this season, slow in the early stages. Rosberg in ninth holding up a train of cars behind him, headed by team-mate Michael Schumacher.
Jenson Button not keeping pace at all at present - he's five seconds adrift of Vettel already. That does mean that Fernando Alonso is losing ground on the leaders in fifth.
Hamilton getting to the first corner first is a big help, but having Vettel on his tail is not quite what he'd have preferred. As it stands, Vettel just out of the DRS zone.
Grosjean has lost his telemetry information, and is going around a little 'blind' as a result.
Hamilton posts a 1:56.779 which is the early fastest lap of the race.
Webber, Rosberg, Senna and Glock all went on to the escape road. We'll see what action is taken.
Stewards are investigating the cars using the escape lane at the first two corners. Rosberg was amongst them, and at first glance it seemed they just ran out of room. The question will be whether they then gained places.
Left-rear puncture for Massa - he makes it into the pit stop, has the tyre changed, and his suspension is given a once over as well for good measure.
What's happened to Massa? It looks like he's dropped well back the field as well.
To make matters worse for Caterham, it's Petrov's team-mate Heikki Kovalainen who hit him. Is there race all but over before it began?
No, not quite - someone has had a shunt - Vitaly Petrov is limping around the back of the field without his front wing.
Vettel takes second, Button up to third. Somehow all the cars got through the first corners unscathed.
Hamilton gets to the first corner first! Maldonado going backwards.
GO GO GO!
Hamilton arrives on his pole position - the last two pole-sitters have led from start to finish - can Hamilton do the same?
Drivers off and running for their warm-up lap. Everyone in the top 10 on super-soft tyres. It's warm in Singapore even at this point in the evening, and it will be demanding on tyres and drivers alike.
How do you see this one panning out? You can tweet me your thoughts and predictions to @Mark_Eurosport
Whatever else there is to say about this race, the scene is pretty as a picture. The streets are lit up, and there's no doubt that the FIA will be pleased to have agreed a five-year extension to Singapore's GP contract.
So the preparations resume after a song and a minute's silence for Watkins. Singapore's circuit is a long street track, and if you need a quick recap of how it looks, there's still time to check out the race guide.
There's a tribute currently taking place to former F1 doctor Sid Watkins - Watkins died at the age of 84 last week.
Lively qualifying session yesterday, which ended up with Hamilton on pole, but plenty of contenders for the race win in close proximity.
A quick newsflash from the last hour - Williams's Bruno Senna has had a gearbox change. Accordingly, he is relegated from 17th to 22nd on today's grid.
Welcome to live coverage of the Singapore Grand Prix from the Marina Bay circuit! High hopes for Lewis Hamilton today as he starts from pole, aiming for his second race win on the spin.
