Approaching the end of the first test with just over one hour to go. What have you taken away from these three days of testing? Anyone or anything caught your eye?

That is it for Aston Martin as they call it a day because of reliability issues, which have also ended Alpine and Haas' testing early.

Dank: It could be Arrows [15:24 GMT], but it could also be Spyker?

Presumably Arrows, JJ?

JJ Jackson: Apropos nothing, in today's shots MCL livery reminds me of European (?) racing team from early 00s. Orange was the sponsor.

Lewis Hamilton, on the C2 tyre, does a 1:23.030 as he keeps improving.

Other drivers are also finding more time on their laps as Daniel Ricciardo is round in 1:21.448.

Alpine’s test might be over already but that doesn’t mean reserve driver Oscar Piastri isn’t still working. The highly-rated Australian won three junior category titles in a row but was unfortunate to miss out on a race seat this year, so he’s very much in learning mode awaiting his chance. So he’s using this afternoon to check out some rival cars trackside.

Lewis Hamilton is on slicks and he is entering some more representative times with his latest a 1:24.795.

The times have been really coming down following a move to slicks from the handful of drivers out on the track and Carlos Sainz does a 1:22.311.

Sebastian Vettel had a dramatic stop just before the end of the morning session with a fire breaking out on his car. Aston Martin have issued an upate on what happened:

Pierre Gasly: “I am really pleased this decision was made. It is completely the right one. Knowing they are in war. I don’t support the action they are taking. It is a relief F1 is also cancelling the grand prix.

“About Ukraine, it’s really sad to see what’s happening. In 2022, to see innocent people… breaking families and dying from basically a reason which I don’t support is very sad and seeing all these videos.

“I am also personally affected having some people close to me in Ukraine right now. It’s a very difficult situation and very scary because they don’t know if they are going to be able to make it out and see their relatives.”

Lando Norris: “Sad to see what’s going on. A very good decision from F1. Not a place I would want to be going right now and very sad to see what’s going on and the innocent lives that are being taken.”

Alex Albon: “I think it’s the right step. It’s really saddening. There are much bigger things out there than racing.”

Some of the drivers gave their thoughts on the news that the Russian Grand Prix has been cancelled following the country's invasion of Ukraine.

Here's what some of them had to say...

Here's the latest times with this afternoon's done in the wet (times in bold) obviously not getting close to the morning times.
