Norris makes a big improvement to sixth ahead of team-mate Piastri. But he is really, really struggling here and could be at risk of a Q2 exit.
Antonelli clipped the wall on the inside of Turn 1 as he opened up a lap. He's done too much damage to continue.
Verstappen improves to take over top spot with a 1m44.041s and leads a Red Bull 1-2.
Leclerc pops up to third in the Ferrari.
Antonelli won't start last on the grid, as he's currently seventh. But he's likely to start 16th.
Norris is only 12th after this lap. He says there's something wrong with his car.
But Verstappen is only 0.002s down on Russell. This feels like game on for pole later on in Q3.
Russell, meanwhile, has gone fastest with a 1m44.277s.
Huge drama!
Championship leader Antonelli is out of qualifying!
Kimi Antonelli says he has hit a wall on this lap. He's still going round but he's damaged his front left wheel!
The bottom six so far:
- Hulkenberg
- Gasly
- Alonso
- Bottas
- Stroll
- Albon
With nine minutes to go in Q1:
- Hadjar
- Hamilton
- Piastri
- Verstappen
- Leclerc
- Antonelli
- Colapinto
- Norris
- Russell
- Sainz
That 1m44.702s is quite a bit faster than Hadjar managed in FP3.
Hamilton up to second in the Ferrari.
"The front locking is terrible," complains Russell on the radio.
Hadjar now goes fastest in the sister Red Bull with a 1m44.702s.
Max Verstappen now goes top in the Red Bull on a 1m45.168s ahead of Kimi Antonelli.
It's Colapinto from Bortoleto and Lawson at this early stage of Q1.
Colapinto sets the first proper flying lap at 1m45.768s.
The first laps on the board are miles off from what we saw earlier, so everyone has clearly been warming up. Perez leads with a 1m55.905s.
Lance Stroll has had a brief off already down at Turn 7. Not the first driver to do that today.
We did see in practice that the soft wasn't delivering the best times on opening laps. There is a lot of life in this tyre.
Verstappen overtakes Russell on the straight, but the Red Bull doesn't actually go for a push and continues to warm his tyres.
Everyone is out there on soft rubber for the start of this session.
Potentially a big session for Cadillac coming up. Sergio Perez has the ADUO Ferrari engine upgrade this weekend and he has been pretty quick on it.
Caddy could well get into Q2 for the first time this season.
