Hello and welcome to our LIVE lap-by-lap coverage of the title deciding Brazilian Grand Prix. Lights out at 16.00 GMT!

Hamilton passes Button for second! Hulkenberg still leads. Alonso fourth from Kobnayashi and Vettel. Still good enough for Vettel.

The safety car is in. Webber runs wide to avoid contact with Vettel and Kobayashi also challenged for fifth. And Kobayashi did get past Vettel!

Still they sit behind the safety car. Should only be one more lap. It’s still raining.

Alonso has reported that it’s raining again into turn 4. Button also complaining that the safety car is going too slowly and he is losing tyre temperature.

As it stands, Vettel would win the title by 11 points with 283 points to Alonso’s 272.

The safety car is still out.

Hulkenberg and Button have indeed taken the opportunity to pit for the hard Pirellis that should see them to the finish.

No matter where Alonso finishes, fourth is good enough for Vettel. Safety car still out.

Not great news for Hulkenberg and Button who have lost a huge lead now. They were almost 40 seconds clear.

And we now have a safety car deployed due to debris out on the circuit. Good news for Vettel.

Still Hulkenberg leads by under a second from Button. Hamilton third from Alonso and Vettel.

As it stands Vettel would win the title. Hulkenberg leads from Button, Hamilton, Vettel and Alonso.

The circuit is drying out. Vettel is in from fourth! Webber also in.

And Nico Hulkenberg leads the Brazilian Grand Prix after taking Jenson Button! Lewis Hamilton in for new rubber. Alonso in too.

Really interesting now. Hulkenberg right on Button’s tail and Vettel is behind Alonso. Fantastic racing in this final grand prix of the season. Just what we wanted.

The drive of the day though is surely from Sauber bound Nico Hulkenberg. He challenges Button for the lead but Button defends.

Vettel takes Kobayashi for fifth. This is a great drive from the Red Bull star.

So on lap 15 the standings are: Button, Hulkenberg, Hamilton, Massa, Vergne. Hamilton is saying his tyres are going off. Vettel up to eighth so looking good.

A lot of cars have still not pitted and the track is very slippery. You would think Button and Hulkenberg must pit soon.

Hulkenberg is also choosing to stay out. So Button leads from Hulkenberg and Hamilton. Massa is fourth from Alonso. Vettel is tenth. As it stands, Alonso would be champion by two points!
