The formation lap is under way. Will everyone make it round? We've already had a few have to start races from the pitlane this season after formation lap woes.

Everyone starts on the soft tyres, apart from Kimi Raikkonen down in 17th and it's mediums for him.
'The slipstream could be a factor'published at 13:59 British Summer Time 9 May 2021
Jolyon Palmer
Former Renault driver on BBC Radio 5 live sports extraThe drivers have done so many practice starts over the weekend. It will be absolute focus on the lights and then the procedures. It is a long run down to Turn One. The slipstream could be a factor which will favour those on the second row. It will give Bottas and Leclerc chance to attack.
Hamilton can think about team play. Let Bottas take his slipstream and they can both pull away from Verstappen.

End of twitter post'The start is crucial'published at 13:56 British Summer Time 9 May 2021
Ben Edwards
F1 commentator on BBC Radio 5 Live Sports ExtraThe start really is going to be crucial. Getting into the lead on the opening lap could be the decider of who wins this race.
How they standpublished at 13:54 British Summer Time 9 May 2021
Three races gone and it looks like a season of just two challengers for the title. Hamilton holds an eight-point lead over Max Verstappen, who is already 24 points clear of Lando Norris in third.

With drivers talking about tracks being difficult to overtake on, and F1 wanting more overtaking, perhaps it is the tracks that need changing rather than the cars.

Pirelli's advicepublished at 13:51 British Summer Time 9 May 2021
Here's what Pirelli suggest. Those on the softs should look at a two-stop strategy and drop the softs after 19 laps, then go on the mediums for 28 laps before another 19 laps on the softs.
Mercedes have hinted that it's a one-stop for them, so they will be aiming to get to about the 25 lap mark before doing the rest on the hards.

Image source, Getty ImagesThe teams’ computers predict this race to be on the cusp of one and two stops. Traditionally, it is hard to make a one-stop work in Barcelona and it will involve a fair bit of tyre saving. So decisions will be made as the race develops.
The hard tyre is said to be too slow to be used in the race - but they said that before Portugal last weekend and it actually proved to be the better second-stint tyre than the medium.
In terms of tyre availability, Max Verstappen has one new set each of the soft, medium and hard tyres. The Mercedes drivers have no new softs, but a used set of mediums as well as one each of new hards and new mediums. Pit-stop time loss is about 22 seconds under racing conditions, 12 under caution. Overtaking is hard.

End of twitter postWords from Wolffpublished at 13:48 British Summer Time 9 May 2021
Mercedes boss Toto Wolff, speaking to Sky Sports: "There are a few variables - the slipstream and the better line. Whoever comes out first [at the first corner] has a pretty decent chance to win."
Wolff says Mercedes will aim to do a one-stop unless someone "does something crazy" behind.

Time for Formula 1's message of unity in the We Race As One video - featuring all 20 drivers.
As we've seen repeatedly since last season some drivers then 'take the knee' with others choosing to stand.
'Good job'published at 13:43 British Summer Time 9 May 2021
Will today be the day for George Russell, yet to earn a point in 40 races in the Williams (although he scored three in a one-off for Mercedes)?
Once again he outqualified his Williams team-mate and hauled himself into Q2. It's a starting spot of 15th today.

Jennifer Harries: Can we have another 2016 please? Where the two Mercedes drivers take each other out and perhaps collect Max Verstappen in the process. Time for a change it's becoming a borefest.

Samwich Toaster: With not much chance of overtaking today and the McLarens looking pretty quick, I'm hoping for a good start for Lando Norris!! Easily one of the most likable drivers in F1 for quite some time!
Norris has had a superb season so far - with better results than team-mate Daniel Ricciardo in each race this year. The Briton came fourth in Bahrain, third at Imola and fifth in Portugal.
