The locals have been loving Formula 1 being back in Mexico and have flocked in their thousands to the circuit.

No driver has got a bigger cheer so far this weekend than home favourite Sergio Perez. He finished on the podium at the Russian GP last month, and will be hopeful of becoming the first Mexican to finish higher than fourth in his home race.

"For the race expectations will be high, I know that, but it's a very positive pressure and I just need to say focused," he said. "The car is working well, we've done our homework and I want to move forward in the race."

There are a few clouds above the circuit, but none that look particularly threatening. Here's the latest forecast from BBC weather's Ian Fergusson:

"Increasingly cloudy. Perhaps a few light showers later but more likely wet post-race."  

"I'm happy being in first and it's going to be an exciting race," says Nico Rosberg. "I've got a good car so it's going to be good. It's very important I get a good start.

"Our car is quick in any condition. I'm first so I would prefer it to stay dry but if it rains no problem."

Nico Rosberg's face in this picture is freaking my mind!

It is a truly superb atmosphere at the circuit, with the packed grandstands entertained by a Mariachi band while the drivers are driven round the circuit in a fine array of classic cars.

Sunshine at the moment, will it last for the race?

Mercedes, when not hooking up the fastest car on the grid, are a dab hand at history-making too. 

They've just tweeted this graphic of Mexico GP winners over the years, starting all the way back in 1963 with Jim Clark. There are some big names there, so illustrious company awaits for today's victor.

Race highlights will then be on BBC One at 22:30 GMT.

“It has been a while since the Mercedes drivers had a proper coming together - 14 months, to be precise, since the 2014 Belgian Grand Prix, when Nico Rosberg’s ill-judged attempt to say ‘enough is enough’ backfired spectacularly. 

"Rosberg was given a public and private dressing-down by the team after the collision with Lewis Hamilton he caused there, and since then he has been given painful lessons in race-craft time and time again by his team-mate.

"The latest of those was in Austin a week ago, when Hamilton pushed him wide at the first corner. If Rosberg is still smarting from that, he is hiding it well, although there has been the odd little hint of annoyance at Hamilton’s behaviour, and some of the things the new world champion has said. 

"And team boss Toto Wolff has basically admitted Rosberg is still upset. Is this race when he tries to get his own back and lay down a marker for the future?”

Hello and welcome to our coverage of the Mexican Grand Prix.

After Lewis Hamilton wrapped up a third world championship in Austin last-time out, Nico Rosberg has little more than pride to play for in the final three races of the season. Well, second place also, but mostly pride.

Rosberg was hardly jumping for joy at his team-mate's latest triumph, what with cap-gate and having a pop at Hamilton's first-lap aggression, but he insists he that any anger he may have will not affect his driving today.

Will he stay true to his word? We shall see...

For 23 years Nigel Mansell has stood as the last winner of a Mexican Grand Prix.

That honour, though, will today go to a different driver, with Nico Rosberg firmly in the driving seat.

The German may have lost out to Lewis Hamilton once again in the title race, but he needs to send out a message that he can be a bigger threat in 2016.

To do that, he needs to add to his three race wins so far this season, and there's no better time to do just that than today.
