Leclerc and Verstappen are still out there on the soft tyres that they qualified on so I think Lewis will be fine.

Hamilton: "I don't think I'm going to make it to the end of the race on these tyres."

The mediums.

Bottas comes out in second place, 4.6 sec behind the Red Bull.

This is the first time Honda have led a grand prix since Canada 2008 with Rubens Barrichello.

Hamilton: "What's the reason you stopped me so early?"

Hamilton's engineer: "To cover Vettel he's behind by 1.9 seconds."

Eight retirements last season, and he prayed over winter for a better season this time.

Not a great start to the first race, before even reaching the first corner.

Norris' engineer: "Giovinazzi is talking about extending we need to get past him, use the tyres if you need to."

The pair almost had a little tangle, but went off wide without any damage.

Hamilton has pitted but he has no pace. Bottas is easing with fastest lap after fastest lap to the win.

• Valtteri Bottas gets an excellent start to overtake pole-sitter Lewis Hamilton on the opening lap.
• Max Verstappen second, 14 seconds behind Bottas but neither of the top two have pitted. Charles Leclerc third also yet to come in, Lewis Hamilton fourth and Sebastian Vettel fifth but both have pitted.
• Daniel Ricciardo, in his first race for Renault, loses his front wing on the opening lap, has to pit and drops down to last, but is now 18th.
• Robert Kubica has also had to pit early on with a problem for Williams in his first F1 race since 2010.
• Carlos Sainz is the first man out of the race, with his McLaren on fire in the 11th lap. Sainz escapes the car unhurt.
• A pit-stop error from Haas sees Romain Grosjean drop down from seventh to 14th.

Daniel Ricciardo has been shown the blue flags as Valtteri Bottas sails past him. That's going to be strange for the Aussie, he hasn't seen those in a while.

Roxy: Awww Carlos. Is this a sign of what Mclaren are going to be like all season?

Jacqui Baker-Stubbs: Well that was short lived for Carlos Sainz Fingers crossed that Lando Norris can finish!

Kayleigh: Urghh McLaren could you just not?

Rachel T: Ohhhh noooo! Looks like Sainz has Alonso’s car!

Bottas' engineer: "You want to do two more laps (before pitting), your pace is quicker than Lewis'."

Valtteri is on the soft tyres.

That was a terrible pitstop by Haas - they were struggling with the front left tyre. Just as bad as the double-terrible pitstop they did with both Kevin Magnussen and Romain Grosjean in Australia last year.

Gunther Steiner's head will be exploding right about now.

Grosjean's race has unraveled. He lost seven seconds [in that pit stop] compared to what other teams are doing and drops him from seventh to the cusp of the points by the time the other teams have come in.

For a team that can qualify sixth, you have to get the pitstops right and they have just thrown away a few points.

Vettel comes out of the pits in sixth but makes up to fifth, Hamilton also pits and comes out in fourth.

Our leaders are:

1. Bottas
2. Verstappen
3. Leclerc
4. Hamilton
5. Vettel

He's the first one of the front runners to make a pitstop.

One-stop strategy perhaps?

Babatunde Sakiru: False start has always been Lewis problem, I suggest he gets more practice on that.

Denislov Lietnev: I hope Mercedes won't play favorites and just let its two drivers race!

Josh Earl: Really unfortunate for Ricciardo, especially on his home Grand Prix

That is an old-fashioned engine blow-up. They will not be salvaging many parts for that. McLaren moved from Honda and are with Renault and Sainz is out of the race through no fault of his own as his car has given up on him in a big way.

Just as Zak Brown said the cars were running well, Carlos Sainz's car sets on fire... He pulls into the pitlane.

As he quickly climbs out of the car and gets sprayed with a fire extinguisher.
