Hamilton: "Something is wrong with my right mirror. It's moved."

From the live timings, it seems like Lance Stoll is the only driver to not set a lap time yet.

There is just under 20 minutes to go.

"The car is so unpredictable in Turn 9, Turn 1. You don't know when the rear is going to step out."

The C2 hard tyres, C3 medium tyres and C4 soft tyres have been selected for the Bahrain Grand Prix in Malaysia.

Everyone has the soft tyres bolted on apart from the McLarens and Red Bulls that are on the medium compound and Charles Leclerc still has the hard tyres bolted on.

The Mercedes cars are looking fast, but Max Verstappen has just gone the best part of half a second faster than Lando Norris in sector one alone on a set of mediums.

OK, it's a new set of mediums and the track is ramping up, but the two Mercedes are looking strong, as well as Verstappen, at this stage.

Kimi Antonelli has completed a fast lap and tops the leaderboard. The Mercedes driver is on a time of 1:36.924.

He is followed by team-mate George Russell in second.

Isack Hadjar has been on the radio to say his Red Bull is unpredictable.

We're halfway through the session and we've learnt... erm... nothing, really.

All 22 cars are out on track now for the final practice session.

The top three are currently McLaren duo Lando Norris and Oscar Piastri on the mediums and Ferrari's Charles Leclerc on the hard tyres.

Bearman: "I didn't know what that was."

Engineer: "Yeah we've seen that on the front right."

Bearman: "First I thought that was the tyre but it wasn't."

And we are back. Session has resumed after the debris is cleared off.

There is just 30 minutes left of the session.

It tends to be in the afternoon when it rains; the humidity builds up, the clouds build, and we saw that happen on Friday. At the beginning of second practice, it was a 90% prediction of rain before the session started. But it all kind of broke up, and it does sometimes to that.

One of the striking things is how few wet races there have been in Malaysia, and in Singapore, despite that fact it couldn't be more tropical. But when it does rain, it really, really chucks it down, but then it dries up really quickly because the sun is so powerful.

The red flag has been waved. There is a bit of debris out on Turn 10.

The session has been stopped and the drivers head back to the pits.

It looks like the debris came off Oliver Bearman's Haas.

The two McLarens are now out on the circuit and both Lando Norris and Oscar Piastri are the only two to have the yellow medium tyres bolted on.

Everyone else, apart from Charles Leclerc, has the red soft tyres on for the final practice session.
