F1 Barcelona GP live commentary and updates - FP1

F1 TV cuts to the other Williams garage, where Browning's car is still up on stands with its nose off, surrounded by mechanics.

Sainz, having been pushed back into the garage, now emerges and joins the track.

Iwasa also circulating with a substantial array of pitot tubes set up behind his Red Bull's front wheels.

Just an installation lap for F2 champion Leonardo Fornaroli in a McLaren garlanded with aero rakes behind the front wheels. Lots to do for the Woking team as it tries to get on top of the problematic front wing it first tried in Canada, and which is the foundation of a new development path.

ROOKIE ROUND-UP

This being Barcelona, a track most drivers could lap while asleep, seven teams have elected to 'spend' one of their mandatory rookie FP1 outings here.

We'll be seeing:-

Frederik Vesti (Mercedes, in for Antonelli)

Dino Beganovic (Ferrari, Hamilton)

Leonardo Fornaroli (McLaren, Norris)

Ayumu Iwasa (Red Bull, Hadjar)

Paul Aron (Audi, Hulkenberg)

Luke Browning (Williams, Albon)

Colton Herta (Cadillac, Perez)

GASLY BUSINESS

As you can imagine, the Alpine case has opened a can of worms and not all the pitlane is united behind the Enstone team. Haas team principal Ayao Komatsu, for instance, said Alpine should have left more margin.

Aston Martin's chief trackside officer Mike Krack said his team noted the pitlane was bumpy – perhaps because the cranes used to assemble the pit complex hadn't been 'parked' on platforms to spread the load. So Aston Martin made sure to include a little margin in the settings for its pitlane speed limiter.

So, yes, all the people who left margin are saying "I told you so" to the ones who didn't.

The biggest loser in all this, of course, is George Russell, who was handed a drive-through penalty for not serving his 5s ping for pitlane speeding. It's one thing to undo a 10s time penalty, quite another to engage in a complex unpicking of where someone might have finished had they not incurred a drive-through.

HOLA FROM BARCELONA!

And before we even get rolling with on-track matters, some huge news overnight as Alpine was first granted a right of review into Pierre Gasly's pitlane speeding penalty in Monaco – highly unusual given the high bars set in such cases – then that penalty was overturned.

Let's get you up to speed with the news itself, Gasly's reinstatement to third place, and Alpine's initial reaction. Our trackside team have just been to an impromptu press conference with team boss Steve Nielsen, so we'll have that for you shortly.
