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

And Sebastian Vettel is world champion for the third time as Jenson Button wins the Brazilian Grand Prix behind the safety car. What a race and what a season! Thanks for joining us and congratulations to Sebastian Vettel and Fernando Alonso.

ONE LAP REMAINING! Kobayashi has spun and drops a couple of places. Button is on his way to victory and Alonso is second from Massa and Webber. Hulkenberg fifth from the soon to be three time world champion. Di Resta has crashed in the final sector!

Three laps to go. All the pit stops out of the way and Vettel has a clear track. Alonso still second and has driven his heart out. He needs some reliability issues from Button to help him out.

Vettel being urged to ‘keep it on the black stuff’ by his pit crew.

You couldn’t have wished for a closer end to this amazing season. Vettel could win the title by a single point. Amazing stuff.

FIVE LAPS REMAINING! Vettel looks set to win his third consecutive title. He is sixth. Button leads from Alonso, Massa, Webber and Hulkenberg.

Schumacher pulls over and allows Vettel through to sixth! The only way Alonso can win is to win the race and hope that something happens to Vettel. Vettel three points clear as we stand.

As is stands, Vettel would win the title by just one point! He is urged just to keep the car on the track. If he does that, he is champion again.

Button has reported back that he is happy on the intermediates despite the increasing rain. Alonso is allowed past Massa for second but Vettel is still seventh, which is enough.

The rain is really coming down now and full wets may be required. My word, Brazil never ceases to throw up drama. Memories of 2008 literally flooding back. Hamilton gets a round of applause and he really should have won this race but for that misfortune.

Ten laps to go so here is how it stands. Button leads from Hulkenberg and Massa. Alonso is fourth and Vettel seventh. Vettel would win the title as it stands but more rain is expected. Anything could still happen.

Alonso is now third and Vettel is ninth. As it stands, that’s enough for Vettel. Just!

The rain is coming down much heavier now. Now Button comes in for intermediates.

Now Alonso is in for intermediates! So much to talk about here. Hulkenberg is still running but has a drive through penalty.

It’s started raining again and Vettel got it wrong. He’s had to pit again for intermediates. Alonso must pit as well though so it could be okay.

Hamilton and Hulkenberg have collided in the battle for first into turn one and Hamilton is out! Oh that’s a shame for Lewis. That was Hulkenberg’s fault as he slid out into Hamilton. Button leads.

Looks like Raikkonen has made a mistake and spun. He rejoins near the back.

Vettel in for soft compound for soft slick tyres! A big gamble there. If it rains again, he could be cooked!

Twenty laps until the title is decided. Vettel still fine in seventh.

Just to add to the drama, Sebastian Vettel has lost contact with his team as his radio has malfunctioned! Rosberg in for intermediates.
