The Williams of Carlos Sainz and Alex Albon are up in eighth and ninth - a huge difference from second practice, when they were at the bottom half of the leaderboard.
Rookie Kimi Antonelli is up in sixth and George Russell has put his Mercedes into the third spot.

Mercedes have left it quite late to set a lap time, understandably, as track temperatures are coming up a little bit more, and they're just waiting for the soft tyres to be at their best.

It has got a lot busier in the pit lane now. Lando Norris is heading out in the McLaren but his team-mate Oscar Piastri is waiting patiently. And similar with Ferrari: Lewis Hamilton has been released already by the team but Charles Leclerc is waiting for his turn. So, a bit more action!

It's lovely and warm here, 24C. But if you look up, there is a lot of cloud cover, especially over the circuit. There are some dark clouds but I've checked the weather forecast and there is a zero chance of rain, so hopefully we get a dry final practice session.
Rosanna Tennant, Ben Edwards, British racing driver Alice Powell and F1 correspondent Andrew Benson will be joining us for the radio commentary.
