F1 Monaco Grand Prix: Kimi Antonelli wins after red flag, Oscar Piastri promoted to fourth

The Monaco Grand Prix did not disappoint tonight.

It was wild from start to finish, and there are plenty of unhappy drivers.

But Kimi Antonelli is one very happy driver after winning the race in superb style.

At the time of this post, the final classification has not been made official.

For all updates, go to ABC Sport for the latest news.

Goodnight.

George Russell was leading in Canada when his engine failed.

Today, he was up to third when he was forced to serve a drive-through penalty.

He was originally given a five-second penalty for speeding in the pit lane, which so many drivers got it looks odd.

When he pitted under the safety car, his team did not wait five seconds, meaning he copped a drive-through penalty.

Here is what he told Sky Sports:

In the pit stop, just major confusion and getting a drive-through - the punishment doesn't fit the crime," he said,

"The rules are the rules, if you don't serve the penalty, it is a drive-through.

I don't know what to say.

Two races in a row; could have won last week, could have been P3, P4 today. That is 40 points down the drain.

Good heavens, Alan, I hope it's soon.

My fingers and toes are crossed for a speedy resolution.

Here is the provisional top 10:

1. Kimi Antonelli
2. Lewis Hamilton
3. Isack Hadjar (under investigation for red flag infringement)
4. Oscar Piastri
5. Liaw Lawson
6. Arvid Lindblad
7. Pierre Gasly
8. Alex Albon
9. Esteban Ocon
10. Sergio Perez (under investigation for restart infringement)

If Hadjar is penalised, Piastri will be on the podium.

If Perez is penalised, Aston Martin will have their first point of the season with Fernando Alonso.

If Perez is cleared, it will be Cadillac's first ever point in F1.

Here are the words of Lewis Hamilton after the Ferrari driver finished second in Monaco.

I have to start by congratulating Kimi and my old Mercedes team … Kimi is delivering weekend in, weekend out.

We have been progressing over the past few months, we can't keep up with them yet.

But to get another second place in Monaco under the hardest conditions, I'll definitely take it.

The car is good, but we need more downforce ultimately and with the different scenarios we had out there, holding onto the tyres was tough.

Isack Hadjar is third — for now.

The Red Bull driver struggled all day with power issues. If he does survive the steward's investigation, this will be a magnificent result.

Within the first 10-15 laps I started having massive driveability issues, if there is one track you don't want that it is here. It was massively challenging, even at the end I was lacking power at the restart.

Kimi Antonelli's lead in the drivers' championship is 66 points.

He leads Ferrari's Lewis Hamilton, who is now second.

George Russell scored no points after the drive through penalty.

Oscar Piastri has crossed the line in fifth.

The penalties to Pierre Gasly mean he is elevated to fourth.

Third-placed Isack Hadjar is under investigation for a red flag infringement, which is being investigated after the race.

Teenager Kimi Antonelli has overcome late safety cars and two standing starts to win a chaotic Monaco Grand Prix, extending his lead in the Formula 1 driver championship.

Kimi Antonelli is away and clear.

He has two full laps left to win the race, and extend his lead in the drivers' championship.

Oscar Piastri is chasing Isack Hadjar.

The Red Bull driver is crying out that he has no power.

This is allowing Pierre Gasly to get clear of him, but he needs a 10-second gap.

Isack Hadjar will be investigated after the race.

It is Antonelli vs Hamilton.

The young teen leads by 1.2 seconds.

George Russell comes in for the drive through penalty.

Oscar Piastri is now fifth. If he stays within 10 seconds of Pierre Galsy in third, he will pass him.

The teenager has done it again.

It is a great start.

Antonelli leads from Hamilton.

George Russell is up to third, but he has a drive through penalty coming.

Pierre Gasly this up to fourth.

Isack Hadjar is fifth and Oscar Piastri is still sixth.

Lewis Hamilton has been cleared of a safety car infringement.

He can still win this race.

We will be doing one or two laps behind the safety car.

The rule is, you must stay within 10 car lengths of the car ahead.

This is what Lewis Hamilton and Isack Hadjar have been accused of doing.

McLaren have told Piastri over the team radio to make sure he sticks to the back of Pierre Gasly.

There will be a standing start to restart this race.

Here is the decision from the FIA:

"Field will reform in correct order under Safety Car for one or two laps followed by a standing start. Lapped cars to be released first."

The laps behind the safety car count towards the race distance.
