Hamilton wins after overtaking Bottas at start - Mercedes' 5th one-two victory in a row
Vettel damages tyres challenging for lead at start
Norris and Stroll out after collision
That's the end of this live text on a day when Mercedes claimed the fifth one-two finish in five races.
See you again in two weeks time for the Monaco Grand Prix. A lot of work for Ferrari to be doing in that period.
Thanks for joining us and bye for now.

Image source, AFPLewis Hamilton led Valtteri Bottas to the fifth consecutive Mercedes one-two at the start of this season after dominating the Spanish Grand Prix.
The world champion, who started second, passed Bottas into the first corner and eased away to an ultimately comfortable win, despite a late safety car.
A long way behind, Ferrari used team tactics yet again but lost out to Red Bull's Max Verstappen for third.
But a disheartening performance for the Italian team on a weekend they hoped would make a step forward only emphasised the sense that Mercedes are in a league of their own this year and that the championship fight is already a private one between Hamilton and Bottas.
Hamilton, with three wins to the Finn's two and a point for fastest lap from Spain to add to his tally, leads Bottas by seven points and their closest rival, Verstappen, is a massive 46 points behind, with Vettel a further two adrift, and Leclerc 10 behind him.
Mercedes' lead is not far off two clear wins, at 25 points for a victory, and the size of the advantage at just about the quarter-way mark of a 21-race season underlines Mercedes' superiority.
In the football, Manchester City are 4-1 up and heading to the Premier League title and Mercedes seem to be Formula 1 champions already.
They have a points lead of 96 already. We've only had five races!

Max Verstappen, who stands on the third step of the podium for the second time this season, says: "It was a hectic first corner so I backed out of it and it gave me a good position for the first three corners, but the Mercedes is too quick. I'm happy to on the podium.
Standing next to Mercedes number 44 car, David Coulthard asks: "Why are you stood here?"
Verstappen says: "I’m just looking at it, and seeing what’s different to mine."

"As a team it's incredible, the fifth one-two in a run is really good. I got some points and that's important, every point will count, but I have to find out what happened at the start."

Lewis Hamilton, our winner in Spain, says: "I have to put it down to this incredible team. This is history in the making to have five one-twos - I'm proud of that and proud of every ones hard work.
"It's been a hard first four races, it's a great car and we always get along and we've managed to settle our differences and get out well down to Turn One today.
"It was an interesting start - it was close, I saw the red car go around the back of both Valtteri and I, so I had no idea if they were further ahead, and I knew Valtteri would break super deep so I had to look out for that.
"At the restart, we had just done a pit stop so I was trying to keep the tyres warm and to do a fast lap on the fresh tyres - I haven't had a fast lap all year!"

I called it yesterday, that Verstappen would find a way to beat both of them. They should've beaten the Red Bulls here, and Mercedes are too good.

Verstappen beats both Ferraris again, that's the big thing, I think, coming out of this race.
