The race weekend returns to normal tomorrow, with third practice at 18:30 BST and qualifying getting under way at 22:00 BST.

Williams, Red Bull and Mercedes are in for a busy night in Mexico City. Will the repair work/power-unit investigations be completed without any further issues? Will find out on Saturday.

Let's all go to bed! Enjoy your day tomorrow and we'll catch you at 18:15 BST for FP3 build-up - a very important session ahead of the fight for pole position given the red flags and delays we've seen today.

Night night all.

Lando Norris has been joined by Fernando Alonso and Zhou Guanyu on the medium compound that are being used this weekend. Norris' first timed lap lifts him to fifth on the timesheets. And now Lewis Hamilton and Charles Leclerc finally turn yellow.

Lewis Hamilton is still knocking out the laps on the prototype compound in the Mercedes with five minutes to go. Only Lando Norris and Fernando Alonso are in the pits at the moment - will these two be heading out on the mediums? Yes. I can see a yellow band on Norris' McLaren.

And don't forgot to put your name on them!

Teams have been given a specific programme for this extended session, and with George Russell's crash eating in to a big chunk of that time, it seems the five drivers who missed first practice will only get about 10 minutes to do their runs on the medium tyres.

Over on the telly, James Vowles has resumed his chat with Sky Sports and says the team are trying to get Alex Albon out by the end of this session, but Williams are "running out of time".

The likes of Lewis Hamilton and Charles Leclerc, who sat out of first practice, have yet to switch over to the medium tyres to catch-up on data gathering they missed earlier.

Four cars remain on track now as most drivers have made their way back to the pits after their latest runs on the Pirelli 2025 tyres.

A driver without a time on the board is Alex Albon, whose car is being fixed-up following that contact with the Ferrari of Oliver Bearman in the first hour. Williams, Red Bull and Mercedes are all in for a long night in Mexico.

Jennie Gow is joined by former F1 driver, Jolyon Palmer, and the BBC’s F1 correspondent, Andrew Benson, to look ahead to the Mexico City Grand Prix.

The team discuss Lando Norris’ controversial penalty last time out in Austin, hear from both Norris and Max Verstappen, plus discuss whether the title battle is still on with just five rounds remaining of the 2024 season.

Fernando Alonso and Lando Norris have thrown off the shackles and have decided to put those prototype tyres to a real test. Save the entertainment for Sunday, lads.

Great news over at Mercedes. George Russell was slow to climb out of the cockpit following his high-speed crash, but the Silver Arrows say the Briton has been released from the medical centre and is back with the team.

Definitely shift over for Max Verstappen. Now the floor of the Red Bull is being worked on. "Car 1 will not run again in FP2 as we investigate a PU issue further," the team have posted on X. , external

The work on Max Verstappen's car is increasing, so the three-time world champion has jumped out of the cockpit and has probably clocked off for the day without a time on the board in this second practice session.

Now, this is not the most exciting of sessions, which Pirelli boss Mario Isola said he does sympathise with when speaking to Sky Sports earlier, so thanks to Alpine's, external social media account for supplying us with an interesting fact.

"With an elevation of 2,200m (7,300), Mexico City is by far the highest track on the F1 calendar The next-highest venues are in Sao Paulo and Austria, both of which are under 800 metres (1,300 feet) above sea level."

Carlos Sainz is quickest on the prototypes followed by Oscar Piastri and Yuki Tsunoda.

Fernando Alonso is set to become the first driver to compete in 400 Formula 1 grands prix in Mexico City this weekend.

His career has been filled with memorable moments, from his first race start to the iconic sunbathing image - but how well do you know the two-time world champion?

Take our quiz here and find out.

Oh dear. A radio message for Max Verstappen delivers some not-so-good news. "Recharge please, Max," Gianpiero Lambiase tells the championship leader. "Same problem, so box."

The delay has handed Red Bull some vital time to have a look at Max Verstappen's car. The three-time world champion has been struggling since first practice, and with McLaren expected to be strong at Autodromo Hermanos Rodriguez, he can't afford to concede vital points to his rival Lando Norris. Remember Verstappen leads Norris by 57 points in the championship with 146 still available.

OK, on we go with the prototype tyre test.
