Max Verstappen has called into to say he's not got the best grip on these medium tyres. Over at McLaren, Lando Norris is told Plan A is probably the way to go.

For Oscar Piastri, who was knocked out in Q2 yesterday, he's made his way into the points and up to seventh.

Charles Leclerc ran off the track and clearly gained a massive advantage. Not only did he hold his position having got around the outside of Lewis Hamilton, you can even argue that he made the overtake off the race track. The stewards will frown upon that.

Charles Leclerc has increased his gap to Max Verstappen to about two seconds over Red Bull's Max Verstappen, who opted to. start on medium at lights out.

Sergio Perez, in front of his adoring home fans, has climbed all the way up to 14th in the Cadillac.

Charles has been making noise all day long about how difficult it was going to be to pass. He had in his mind that you absolutely have to get to the front of the race and he has got himself in the front but he might have incurred this penalty.

The problem is you can't instigate an instruction for a guy at Ferrari to fall back behind Max Verstappen. Isn't he supposed to fall back behind Lewis?

The virtual safety car is cleared and we're racing again in Mexico. Championship leader Kimi Antonelli is closing in on Lewis Hamilton, who is on used soft tyres. The Italian would love a podium to cap off his championship-winning (as it stands) weekend.

Turn Four was the flashpoint for Charles Leclerc and Lewis Hamilton,which is still under investigation by the stewards. The Monegasque driver was on the outside of Hamilton and both end up off the track.

George Russell fell apart at lights out, and the Mercedes driver also made contact with Isack Hadjar's Red Bull, sending the Frenchman spinning out and down to the back of the field.

It's turned into a miserable day for Aston Martin, who now ask Fernando Alonso's team-mate Lance Stroll to pull over and stop the car. The Canadian does as he's told, and the virtual safety car is deployed.

Charles Leclerc leads, Max Verstappen is 1.2 seconds behind and Lewis Hamilton, who started on pole, is third.

Fernando Alonso joked after qualifying he was heading to Brazil following another disappointment on Saturday. He did start the race today, but now he's being asked to retire the car by Aston Martin.

Race leader Charles Leclerc is 1.7 seconds ahead of the red Bull of Max Verstappen, but the Monegasque driver is under investigation for his fight with Lewis Hamilton, who is running in third spot, ahead of Kimi Antonelli.

Hamilton: "What's happening about Charles?"

Engineer: "Investigation ongoing and they will let you know."

Ferrari are not going to be pleased in asking the stewards to look into the challenge there on the Ferraris because if they give a penalty to Charles, then Max is in the front of the race.

The stewards think the Charles Leclerc-Lewis Hamilton intra-team battle needs investigating. The seven-time world champion then comes on the radio to ask his pit wall what's going on?

Lando Norris also lost out during the first-lap tussles but now the world champion is up to seventh place after overtaking Franco Colapinto.

Championship leader Kimi Antonelli is fourth.

Lewis Hamilton also went off the track in that scrap with Ferrari team-mate Charles Leclerc, so let's see what the race control makes of that incident.

George Russell has passed Arvid Lindblad and is now running in fifth place, while Franco Colapinto has climbed from 11th to seventh in the Alpine.

We said it was going to be chaos and that is exactly what happened. But it was the two Ferraris going wheel to wheel, they didn't give each other an inch. Lewis Hamilton, I'm sure will be furious with his team-mate, they pushed each other all around the outside.

Isack Hadjar was spun round on that opening lap and has now tumbled down the field and is behind pit-lane starter Liam Lawson.

Max Verstappen thinks Charles Leclerc should be giving the position back, while Lewis Hamilton is adamant his team-mate pushed him off the track.

Verstappen: "Charles has to give that position"

Just a little point to make which is, everyone behind the front row, apart from Isack Hadjar, have got new tyres so the front row have slightly less grip off the line. It is going to be very close going into Turn One.

Will this be a championship Sunday in Mexico?

George Russell has lost places on that long run down to Turn One and as everyone makes it out of Turn One, the Mercedes man has dropped all the way down to sixth.

Charles Leclerc is battling with Ferrari team-mate Lewis Hamilton and now the Monegasque driver has passes the seven-time world champion! But will he have to give the position back? There was chaos as the two fought for the lead.

Max Verstappen on his medium tyres has made his way up to second behind Leclerc.
