Good stuff from Bottas. Not the most dazzling of races, partly because Ferrari's odd choices meant the pressure was off Mercedes, really, but nice for the Finn to win here after losing out last season.

And that's the chequered flag - a win for Bottas, a 1-2 for Mercedes - the first team ever to wrap up four consecutive 1-2s at the start of a season.
Bottas starts his final lap - looks like he's going to wrap this up having started in pole.
Hamilton runs wide, loses time - and that chance might have gone now.
Whatever else might be said about Lewis Hamilton, the boy is a racer. He's just clocked the fastest lap of the race and is using DRS to close in on his team-mate.
Decent race for Verstappen, set to finish fourth. One-time leader Leclerc is looking miserable down in P5 - his lap times have not been great at all today.
This has been very poor strategy from Ferrari really - we're all set for another consecutive 1-2 for Mercedes. Bottas still leads ahead of Hamilton, with Vettel in third.
"Keep focused," Verstappen is told over the radio, reassured that he is doing a "mega job". The Dutchman isn't interested in the praise - he just wants to know why the virtual safety car is still out.
Virtual safety car while Gasly is shepherded away.
Oh, and Gasly has some smoke coming from the back of his car. He's been in P6 but is juddering to a halt now.
Leclerc is not going to make any more inroads on the podium places now unless anything bad happens - looks like P5 is wrapped up for him.
He's kept himself out of trouble so far, and Lance Stroll of Racing Point is sitting pretty in the top ten.
Kvyat's retiring from the race after that Ricciardo-reversing-into-him thing.
He's past him, and into P5.
Leclerc's first task on returning to the track is to get past Pierre Gasly.
He's gone onto softs - that took about 2.8 seconds.
FINALLY Leclerc is about to go in to pit.
That is...really not great from Ricciardo. He's incurred so much damage to his car that Renault have to retire him from the race.
So Ricciardo and Kvyat are both still on track for the time being - there's some debris out there.
There's a yellow flag - Kvyat and Ricciardo have had some kind of contact at Turn 3.
Leclerc is suffering with his tyres now and Bottas and Hamilton are closing in.
Ricciardo is duelling with the Haases now - Grosjean in P11, Magnussen in P13.
The Mercs are lapping quickest now, mind - they've got newer tyres on, both on mediums.
So twenty laps in - Leclerc leads, the Mercs behind him, with Vettel pushing them.
Haas are going to have to think about bringing Grosjean in now - he's losing chunks of time on his old tyres.
Renault's Daniel Ricciardo is putting on some pace now too! Good to see after a dismal few races.
And look at Leclerc go. A lap of 1:47.326 and he's in the lead after both Mercedes have stopped.
Quiet progression from Grosjean, taking advantage of the early stoppers - his Haas is into P8.
Ferrari's Vettel is the latest in - he rejoins in P5, ahead of young team-mate Leclerc.
Gasly is having a good race so far after that disaster yesterday - he's heading towards P7.
Plenty of pitting already this afternoon, with Giovinazzi and Hulkenberg the most recent in.
Not talked about Verstappen much so far - he's up into P4 as he slides through the inside of Turn 1.
At the front of the pack, Bottas is extending his lead over team-mate Hamilton.
Charles Leclerc is moving up through the field, now into P7.
And it's a clean start, everyone is through the first part of the lap safely!
Lights out, and away we go in Baku!
Getting ready now, time for a formation lap.
Catch up on qualifying if you missed it with our report.
Kimi Raikkonen, meanwhile, starts from the pitlane after the front wing on his Alfa Romeo failed a post-session front wing deflection test. He'll be in good company - Pierre Gasly (fuel issue) and Robert Kubica (whacking great big crash in quali) are both starting there too
It's the silver arrows on the front row - Valtteri Bottas ahead of Lewis Hamilton.
Good afternoon and welcome to our LIVE coverage of the Azerbaijan Grand Prix.
