So the drivers under investigation at present are Hadjar and Perez. The result may take a while to be confirmed.
Alpine has requested Formula 1’s governing body the FIA to review the penalties that cost Pierre Gasly third place at the Monaco Grand Prix.
Gasly crossed the line in third place behind Mercedes driver Andrea Kimi Antonelli and the Ferrari of Lewis Hamilton and thought he had secured a podium finish in Sunday’s chaotic race on the streets of Monte Carlo.

Isack Hadjar has kept his maiden podium finish for Red Bull but Cadillac has been denied a first points finish in Formula 1.
F1’s governing body investigated two key incidents following the conclusion of a dramatic Monaco Grand Prix on Sunday, with Hadjar and Sergio Perez both at risk of being penalised.

Lewis Hamilton believes he is ‘reminding people who I am’ with consecutive Formula 1 podiums in Canada and Monaco after a difficult few years.
Hamilton is in the top two of the championship standings for the first time since the infamous 2021 Abu Dhabi Grand Prix, having finished second to Kimi Antonelli in the last two races.

George Russell claimed to be “beyond frustration” after a drive-through penalty dropped him out of podium contention at the Monaco Grand Prix.
The Mercedes driver has endured a torrid run of bad luck this season, and recorded back-to-back Formula 1 zero scores after being handed a five-second penalty for speeding in the pit lane, before receiving a further drive-through penalty for failing to serve the initial sanction in his next stop.

Kimi Antonelli took a dominant victory in a chaotic Monaco Grand Prix, winning from Lewis Hamilton.
Antonelli stormed into the distance in the early phase of the race after Max Verstappen stalled from the front row and retired on the opening lap.

Andrea Kimi Antonelli further strengthened his lead at the top of the Formula 1 world championship with a convincing victory at the Monaco Grand Prix, which had to be red-flagged.
The 19-year-old Italian converted his maiden Monaco pole position into his first victory at F1’s crown jewel grand prix with a commanding performance that underlined his status as the favourite in the title race.

So the drivers under investigation at present are Hadjar and Perez. The result may take a while to be confirmed.
Hold the phone! A 10s penalty to Hulkenberg for causing a collision has promoted Perez to the points. Cadillac has a point for the first time, but the Mexican is still facing an investigation for a false start.
If he does get a penalty, Alonso would have taken Aston Martin's first point of the season. This is madness.
There's a very good chance that Hadjar will lose the podium however, with an investigation handing over him for a red flag infringement.
Hadjar claims third, with Piastri fourth after Gasly's 10s of penalties are applied.
KIMI ANTONELLI WINS THE MONACO GRAND PRIX!
Onto the last lap we go! Antonelli has a lead of over five seconds.
At the moment, if Piastri can just sit behind Hadjar, he may well take a podium position - although it may come after the race finishes, with the stewards facing a long evening.
Antonelli has checked out by a couple of seconds from Hamilton with three laps remaining. Hamilton is 13s clear of Gasly, who is edging closer to the gap he needs to keep the silverware.
Gasly is in the top three right now, but he needs to pull a significant margin to keep the position.
Russell serves his penalty and drops to second last.
Hadjar has now been noted for a red flag infringement. Is there anything more to throw at the Red Bull driver, as he's cleared for a safety car infringement.
Seven drivers are out, and Antonelli is storming away. Hamilton is chasing quickly, but Piastri could be in line for a shock podium here.
Hulkenberg tags Sainz, and the Williams driver is into the wall at the hairpin. His first retirement in Monaco.
Antonelli leads away again. Hamilton makes a strong start and the field make it through. Hadjar drops behind Russell and Gasly, but Russell has his heavy penalty to serve soon.
Antonelli reports that the track is still broken up, but we are lining up on the grid ready to go once more.
We will have a standing start.
No further action for Hamilton. You do have to question why the rule exists if it is not enforced.
This is bizarre. Hamilton has again left about 20-30 car lengths to Antonelli, with Hadjar nowhere in sight behind the Ferrari driver. Russell reports Hadjar again.
The safety car leads the drivers out of the pit lane, and the race has technically resumed. We are now on lap 69.
