FORMULA 1 Live

- Jenson Button has to stop 100 yards after the chequered flag as he runs out of fuel!

- Fernando Alonso comes in fourth with Felipe Massa fifth - and Adrian Sutil, sixth, had already been lapped.

- Sebastian Vettel takes second place with Jenson Button third.

- MARK WEBBER WINS THE BRAZILIAN GRAND PRIX!

71/71 Mark Webber is less than two miles from a brilliant victory, helped by Vettel's gearbox woes but none the less satisfying for that.

70/71 Button is still over eight seconds distant, while Mark Webber has just produced the fastest lap of the race. Classy stuff from the Aussie.

69/71 Rain now officially ruled out until after the chequered flag, while Alonso is complaining that his DRS has broken.

68/71 Webber is a comfortable leader 13 seconds ahead of his team-mate, who is now 8.8 clear of Button.

67/71 Button overtakes Petrov, but he still has Kovalainen to lap before he can get any closer to Vettel.

66/71 Liuzzi goes out of the race, apparently also with mechanical problems.

65/71 Button cuts the gap to 10.1 seconds from Vettel, but it's still too much to hope that anything will happen.

- Button is 11 seconds behind Vettel, surely far too big a gap for anything to happen barring a worsening of the gearbox issue for the German.

64/71 Vettel almost loses it! He slides off the track on turn eight, running well wide - but it's not a bad placed to do it, and he's able to come back on safely.

63/71 That Button move was a real beauty, set up by dragging Alonso out of shape in turn one.

- BUTTON TAKES ALONSO! He goes into third place with a stunning piece of driving, saving his DRS for the last possible second to blast past his rival out of turn three.

62/71 Button has a chance to take Alonso on turn one - but the Spaniard closes the door!

61/71 Nico Rosberg has now lost almost eight seconds to Sutil in that battle for sixth, while Massa is over 21 seconds behind Button in fifth.

- Button has Alonso in his sights! It's less than a second between the pair as they fight for the final podium spot.

60/71 Current leader Sebastian Vettel now comes into the pits for his final stop - he's got hard tyres on and will likely cruise from here to a second place finish.

59/71 Webber comes into the pits, and as he gets back onto the circuit he's some 23 seconds ahead of Alonso.

58/71 Button has cut the gap to Alonso to 2.5 seconds, but Alonso is a clear 30 seconds behind Mark Webber.

57/71 "It's been a long old year - looking forward to some down time with family and friends," says Lewis Hamilton, who's often looked pretty sick of the F1 circus this season.

56/71 Jenson Button has just done the fastest lap of the race! He's taken 1.4 seconds out of Alonso in the last two laps!

- Button has been told by the pits to rip the hell out of his tyres in the chase of Alonso: "We want qualifying laps til the end" they tell him.

55/71 Alonso has come into the pits, and heads back out half a dozen seconds clear of Jenson Button.

54/71 The conspiracy theory about Webber being gifted a win by Vettel seems far-fetched: the Aussie needs both Alonso and Button to spin out if he's to do it.

53/71 Here comes Jenson Button - and he's asked for another set of hard tyres rather than the softer ones.

52/71 Vettel is six seconds back from Webber, the Aussie simply cruising now.

51/71 Alonso is five seconds behind Vettel - we look almost guaranteed to have yet another Red Bull one-two as it's going.

- Sutil takes Rosberg back at the same place a lap later!

50/71 Sutil and Rosberg did really well to keep apart from each other there, and they're having a cracking battle...

- Great moves by Rosberg and Sutil! The German, nervelessly, sneaks up the inside on turn one to take sixth place.

49/71 Webber still leads by four seconds from Vettel, with the buzz on Twitter suggesting that Vettel is letting his team-mate win for world championship purposes.

48/71 Disappointment for Hamilton there, but what's new? That's the story of his season...

- Hamilton is out of the race! He lost his gearbox completely on turn three, and has to pull off.

47/71 LEWIS HAMILTON HAS GONE OFF!

- It's neck and neck on the way out of the pits - but Massa comes out just in front of Hamilton!

46/71 It's a bit of an ask for Hamilton to keep those tyres for the rest of the race, while Massa now comes in for his last stop. Will he get back out in front?

- Hamilton comes into the pits! With no way past Massa he stops for his hard tyres that will last him the rest of the race.

45/71 Still Webber-Vettel-Alonso in that order at the front, though Button is there on his hard tyres.

44/71 Hamilton just about closes up within a second of Massa as they cross the line again, but Massa's defending very well.

43/71 Five crashes between Hamilton and Massa already this year, but Hamilton is now dropping off Massa's pace.

- Massa is keeping Hamilton at bay, but only just! This is great racing from this pair... The Englishman is weaving all over the back of the Brazilian.

42/71 Webber is almost five seconds clear of Vettel now.

- Massa and Hamilton are tussling all over the track. Is there still time for yet another collision between these two?

41/71 Now Lewis Hamilton is all over the back of Massa, whose tyres are falling off a cliff.

- Seabasian Vettel comes in for tyres and re-emerges three seconds behidn Webber, but seven ahead of Alonso.

40/71 Felipe Massa's old tyres are hurting him: he's just been flown past by Button as if he was driving a Lada Riva.

39/71 Our leader Mark Webber comes in for soft tyres, and as he's not yet had the harder tyre he'll have to come in again. That could help Button, who's on the hard tyres already. If it rains that could be crucial...

38/71 Now Lewis Hamilton has a gearbox problem - his engineers tell him to hang in and hope for the best - while Bruno Senna has lost fourth gear entirely and is slipping back.

37/71 Felipe Massa on what could yet be a two-stop strategy is yet to come in. He needs to last 10 more laps on his current tyres, but the 20-odd seconds he'll save could yet see him on the podium if things go his way.

36/71 Perez spins the Sauber Ferrari, but saves it with a bit of fancy-dan stuntman driving and carries on unaffected in 14th.

35/71 Vettel is just being told on the radio to go as far as he can on his current set of tyres, while Alonso comes in to get a fresh set of softs.

- Lewis Hamilton comes in and gets soft tyres, and it'll be fascinating to see how he does against team-mate Button on those harder ones. There's supposed to be half a second benefit to being on softs.

34/71 Rain is expected to hit in 10 minutes accoring go the radar.... though it's perfect weather still right now.

33/71 Webber has pulled out 2 seconds over Vettel, with Alonso still 7.5 seconds further back.

32/71 Button comes back out in sixth place, behind Felipe Massa.

31/71 Jenson Button is coming in for a tyre change, and he's going onto the harder tyre.

- Alonso is third, 7.7 behind Webber, while Lewis Hamilton and Jenson Button are a further 6.5 and 4 seconds back respectively

30/71 Webber comes through at the start of lap 30! Vettel moves over for his team-mate so as to ensure that he doesn't hold up and possibly jeopardise a win for Red Bull.

29/71 Webber has closed right up on Vettel, and is withing half a second.

- Pastor Maldonado has spun out at turn eight! There's a yellow flag as they'll need to get that car out of harm's way.

28/71 Vettel is now told to short shift - i.e. change up before he normally would - on every corner now as the gearbox comes closer to imploding. Webber must surely come through sooner or later.

- More trouble for Bruno Senna, who misses a gear and lets Maldonado through after losing a chunk of his front wing presumably loosened in that early ding.

27/71 Vettel has backed off and immediately loses half a second to Webber, who will be snffing a morale-boosting win by now.

26/71 The pits come on the radio to Vettel: "You have a serious gearbox problem," they tell him, warning not to go into the red in second or third gear.

25/71 Alonso is slipping back off the pace a little, four seconds behind Webber.

24/71 Vettel definitely handling the gearbox issue better, and he's keeping the advantage well at about 2.7 seconds.

- MASSIVE BLUNDER FROM GLOCK! He pulls away from the pits before his rear left wheel is put back on, and the tyre ends up bouncing all over the pit lane. Glock, wheel-less, is forced to pull off and out of the race.

23/71 Vettel's gearbox issue seems to be coming and going - he's just extended his lead back to 2.9 seconds.

- Vettel's lead after the pit stops has been slashed to 2.6 sceonds over Webber and just under five over Alonso.

22/71 Massa comes out behind Hamilton, and is in sixth place.

- Massa is now coming in to change his tyres - they were really going off at the end, he had no ammo to defend against Vettel with.

21/71 Vettel goes past Massa right at the start of lap 21, and he's free to open it up again and get that lead back up.

20/71 Massa is still staying out, but he now has Vettel hot on his haunches.

19/71 Webber has pitted leaving Felipe Massa in the lead - just - from Vettel, though the Brazilian has to stop. Or does he? Is he gambling on a two-stop strategy?

- Bruno Senna has been given a drive-through penalty for that clash with Schumacher: he might argue that the German turned in, but it was Senna who overran his braking point to put himself in harm's way.

18/71 Sebastian Vettel comes in for new tyres and Mark Webber is now the leader - though the Aussie has yet to pit.

- Lewis Hamilton and Fernando Alonso have both stopped in the pits and come back out in 4th and 6th respectively.

17/71 Vettel's gearbox issue is getting slightly worse, with third gear now affected.

16/71 Having lost third place Jenson Button stops into the pits for new tyres, suggesting that all the front runners will be on three-stop strategies in this 30 degree weather.

15/71 Webber has just taken 0.3 seconds out of Vettel's lead. Michael Schumacher is dead last after that incident, and has been lapped.

- Vettel is suffering from a short shift in second gear, meaning he can't use the full rev range. Nothing major but every bit counts...

14/71 Vettel is on the pit radio complaining of a gearbox problem, but it doesn't seem to be slowing him down....

13/71 Alonso, in third, is now 10 seconds back from Vettel, while second-placed Webber is three seconds behind his team-mate.

- Schumacher has a new set of tyres and is back out, while Senna now comes into the pits for tyres - possibly to be checked out because his front wing is not replaced.

12/71 Alonso has picked up two seconds on Button already - he's really flying.

- ALONSO GOES PAST BUTTON! The Englishman got out of shape in turn four, losing his rhythm and ending up letting the Spaniard through.

11/71 Schumacher and Senna's crash being investigated - it's a bit 50/50 though, possibly no penalty.

- Senna's Renault lost a few chunks of its front wing, but he seems to be running absolutely fine.

10/71 Schumacher has smashed into Senna on the first corner of lap 10! Amazing stuff, and the German has to put with a puncture - he's haemorrhaging places as he limps back to the pits!

9/71 Schumi is still all over the back of Bruno Senna - these two look like they'll have a good tussle.

- Still blistering sunshine, and the skies seem to be clearing rather than clouding over. Rain still possible but it's nowehere near right now.

8/71 Button, Alonso and Hamilton in 3rd, 4th and 5th is the best battle on the track still, the three of them split by less than 1.3 seconds.

7/71 Michael Schumacher, uniquely among the field, apparently has a spare set of soft tyres in the pits as he's started on part-worns.

- Vettel is now just under seven seconds clear of Button, while Michael Schumacher is now hunting down 9th placed Bruno Senna.

6/71 Button locks his brakes and lets Alonso right up behind him, but pulls away in the second half of the lap to reestablish a half-second breathing space.

5/71 Alonso has put in a couple of flying laps, and is right up Jenson Button's backside now - while Lewis Hamilton is way back.

4/71 As the cars come round again the field is tightly bunched from Button in third down to Nico Rosberg in 7th.

- Barrichello has pinched a couple of those lost spots back, and is back up to 17th.

3/71 Vettel now 2.2 seconds clear - utterly stunning, clean driving from the world champion. He's just too good.

- Awful start for Barrichello, who slips down from 12th to 19th on the grid in what might be his final Grand Prix.

2/71 Vettel is 1.5 seconds clear of Webber at the end of the opening lap, with Jenson Button another second further back.

- Michael Schumacher has slipped back into 12th, but already at the front of the pack Sebastian Vettel is already pulling clear of Webber.

- Clean start from the Red Bulls - but Alonso gets off to a flier and takes Hamilton's fourth place straight away!

1/71 The cars line up on the grid... the lights change... and they're away! The last 71 laps of the season start right here!

15:59 The cars are on the grid and we're about to get the parade lap under way... and there they go!

15:56 "The only thing that can stop a Red Bull winning today is the weather." - David Coulthard, whose diploma from the School of the Bleedin' Obvious is presumably on prominent display in the toilet at his glitzy Monte Carlo abode.

15:55 Just a few minutes from the start, and the latest weather news is that the radar predicts a couple of showers at some stage this afternoon. Don't expect a Monsoon, just a sprinkling, and it won't hit until at least half an hour into the race.

15:52 Amazing Rubens Barrichello stat: he's raced in a third of the F1 races that have ever been held in the history of the sport. 20 years and over 320 races... a true legend.

15:50 A priceless moment to help bring down the curtain on the BBC's 'proper' coverage of F1: Brazilian footballing legend Ronaldo is in the pit lane being interviewed when his son, accompanying him, yells "can we go home now?" into Jake Humphreys' microphone.

15:45 Latest forecasts look as if those hopes for rain will be dashed. Scorchio!

15:40 Lewis Hamilton is hoping to see it rain during the race...

15:35 Jenson Button is confident of finishing with a flourish today, whether it rains or not whether it rains or not

15:30 Felipe Massa is celebrating 10 years in Formula One. How else would Ferrari mark that but with a giant cake that looks like it's been made by a primary school class?

15:28 There's no drama with regard to who wins the title, but Jenson Button, Fernando Alonso and Mark Webber are all in with a chance of finishing second. Drivers' standings

15:23 Lotus reckon that securing 10th spot in the championship - despite the fact that they've earned no points this year - will be worth $25 million to them next season

15:20 The forecast suggested that we could see rain, and though there are sunny patches in the sky there are also enough clouds to suggest that we could see rainy chaos in Brazil

15:16 If Barrichello did retire, could the BBC snap him up to replace Martin Brundle? Brundle confirms move to Sky

15:15 Lots of talking points today, we'll kick off with the speculation about Rubens Barrichello's future in F1. Will the legend call it a day at the end of the season? Barrichello: No regrets if last race
