Norris attacks Bottas. Brilliant stuff from the Brit, started seventh, now fifth, attacking fourth.
Max Verstappen had squashed the field up before sprinting off. Leclerc nearly gets ahead of Hamilton as a result.
Lando Norris, around the outside of Pierre Gasly, who bangs into Daniel Ricciardo.
Gasly's front wing has gone.
Safety car coming in. We're going again.

Mazepin is struggling. A lot. So many spins so far - five this weekend. Really, really bad start to life in F1.
"OK Max, we are monitoring that problem you mentioned. No update yet though."
Verstappen had said something felt "weird".
Charles Leclerc is up from fourth to third, switching spots with Valtteri Bottas.
The McLarens of Lando Norris and Daniel Ricciardo have swapped their starting positions, with the Brit now sixth and the Aussie seventh.
Fernando Alonso has gained a place up to eighth, as has Lance Stroll to ninth with Carlos Sainz falling from eighth to 10th.
Sebastian Vettel started right at the back but has already clawed back six spots and is 14th.

Wow! Really, really close fight between the two McLarens but that is neutralised by the safety car.
Great start by Charles Leclerc, up into third. The top two didn't change positions.
"I feel something weird on the throttle on the low speed corners. Can you check on the rear?"
A problem for Sergio Perez and a pitlane start for him, an attack on the lead held off by Max Verstappen and a Haas in the wall.
F1, how we've missed you.
Incredible start to the 2021 season.
"I'm OK"
The top six: Verstappen, Hamilton, Leclerc, Bottas, Gasly, Norris.

Iain Smith: Let's face it. The second Red Bull car is cursed. It's the only logical explanation.
Nikita Mazepin hits the wall. On his F1 debut, inside a minute of his first race.
Hamilton tries to go around the outside of Verstappen, but the Dutchman hangs on to the lead.
After a bit of a delay and some drama, the 2021 F1 season is Go! Go! Go!
Perez: "What was the problem?"
Red Bull: "We're not sure Checo. We are looking into it."

Ignition was straight off. He coasted to a halt. He's back in the pits now so he will start from the pit lane.
That might make Max Verstappen on pole a bit nervous, knowing his team-mate is having a problem with his car.
