Renault, meanwhile, are neatly positioned here. Daniel Riccardo is fourth, and Nico Hulkenberg fifth.

The word from the Toro Rosso pit wall is that Daniil Kvyat was suffering an oil leak.

The virtual safety car ends. As has Daniil Kvyat's race.

Kayleigh: MCLAREN ARE YOU JOKING ME?!?!??

Tracey Pankhust: Anyone else want a penalty, they are being handed out like sweets right now!

Uh-oh - more problems as Daniil Kvyat ends up in the grass. The virtual safety car is deployed again.

1) Leclerc

2) Hamilton +0.833

3) Bottas +7.19

5) Hulkenberg +38.828

That front right wheel was not put on properly at the pitstop.

He's (Sainz) tried to pull away and did go and the McLaren mechanics knew it immediately.

Lap 29/53

Major setback for Carlos Sainz! He leaves the pits with a wheel loose, and has to retire. There's a yellow flag and a virtual safety car.

Valtteri Bottas pits and so has to give up the lead - switching from soft to medium tyres. The Finn emerges in fourth, and Charles Leclerc is back in the lead.

It looks like the Tifosi are enjoying this... The last Ferrari win at Monza was Fernando Alonso in 2010.

I mean... madness is the only way to describe it.

Max Verstappen, who started at the back of the grid, has forced his way into the points - he's past Pierre Gasly and into 10th. Valtteri Bottas still leads, but has yet to pit.

It's not a clever piece of driving from Leclerc. It's a five-second penalty all day long.

How he has got away with that I just do not know.

He's got away with it somehow but the inconsistency is just incredible.

If a driver drives another driver off the road it has to be a penalty.

He's sold the stewards an absolute dummy there.

Hamilton: "He didn't leave me a car's width there - he pushed me off!"

Leclerc's engineer: "Black & white flag."

Leclerc: "WHY?"

Hamilton: "He's super fast on the straights."

Josh Earl: Leclerc lucky to get away without a penalty there, squeezed Lewis off the track.

Jeremiah Kariuki: Leclerc is a hard fighter. But his racing is not acceptable and gets a gift of a Black and White flag. Lucky that's not a penalty.

Tracey Pankhurst: No penalty for Leclerc for pushing Hamilton off track! What’s happening!!!!

Hamilton has another go, but Leclerc squeezes him out - and Hamilton is forced on to the gravel! Hamilton recovers, but he's not happy. He feels he was nudged off.

Leclerc is shown a black and white flag. It means the stewards have assessed the Ferrari man's driving is not acceptable, but there's no further penalty. In football terms, it's a yellow card for Leclerc.

Leclerc squeezes past Nico Hulkenberg at Parabolica. Hamilton follows, and is right on Leclerc's tail!

Hamilton comes in to pit, followed one lap afterwards by Leclerc. The Monagesque comes out ahead, in fourth overall, on hard tyres, but Hamilton, in fifth, is now chasing him down on the mediums. Bottas leads but has yet to pit. The race is on.

Kimi Raikkonen has to serve a 10-second stop-go penalty for starting the race on the wrong tyres.
