F1 Monaco GP live commentary and updates - Race

Let's take advantage of this stoppage to catch up with the comments.

'Has Hamilton served his penalty?' asks Lotus109. We believe he did, hence the lengthy double-stack for Leclerc. In any case, he's not under investigation at the moment.

'Forgive me,' asks chinesegeorge, 'what's a WKD?'

That question kindly answered by another reader, which leaves me only to suggest that you look up 'Cheeky Vimto' on Google and prepare one (if you have the ingredients available) in preparation for more celebrity footage if this stoppage continues for much longer.

Mind you, to be frank most of them bog off before the race begins anyway. That's where Kym Illman paps them, as they head for the exit.

F1 TV showing the track inspection in progress. There is what's best described as a long crater in the track surface on the outside of that corner, surrounded by detritus which comprises chunks of degraded asphalt as well as tyre 'marbles'.

They're cleaning that detritus away but that doesn't solve the problem of the crater.

Presumably on Sky TV, Martin Brundle will be choosing his words carefully apropos the resurfacing process...

Yes, FIA confirms the red flag is for a track inspection at Turn 19.

And a 5s penalty for Pierre Gasly.

Russell under investigation for not serving his penalty correctly.

Leclerc back in the garage and not a happy bunny at all. No surprise there - those front wheels just locked completely on the way into the corner, skating over the marbles.

Gasly now under investigation for pitlane speeding again.

Russell, of course, one of the lapped cars being allowed to unlap themselves. He's querying on the radio whether he has served his penalty or not. "We'll relay the messages as they come," says race engineer Marcus Dudley.

So it's Antonelli, Hamilton, Leclerc, Hadjar, Russell, Gasly, Piastri, Lawson, Lindblad and Albon.

So this has worked out very nicely for Racing Bulls. Piastri lost just one place by serving that penalty.

Lapped cars being allowed to pass the safety car so we're not far away from restarting - lap 64 of 78.

All the frontrunners on used softs apart from Hadjar in P4, who only had a used set of hards to play with. Ditto Gasly.

Busy evening for the stewards, then.

Yes, replays showing that was the case.

In all that flurry, we note that Russell didn't serve his penalty during that stop.

Leclerc continuing to fulminate over the radio.

Antonelli into the pits! Left rear is slow to change. Russell, Lindblad, Albon and Sainz in, plus Ocon, Colapinto...

It's a double stack for Ferrari. "Why the hell are we pitting?" harrumphs Leclerc. 

Safety car restart, Charles. Softs versus elderly hards. Do we need to spell it out?

Hulkenberg and Alonso too.

Hamilton, Leclerc and Piastri into the pits.

Replays show Leclerc dinging his front-left wheel rim against the barrier at the chicane exit. Mind how you go!

And, lo, the Williams drivers swap on lap 59. Albon back into P10. He's now 5s behind Lindblad but the VCARB hasn't visited the pitlane yet.

In any case, Antonelli has now lapped Russell.

Antonelli just did a purple sector two and Peter Bonnington was straight on the radio to remind him that there are no points for fastest lap these days.

Antonelli now 26.5s ahead of Hamilton and his last lap was a second faster, so nothing seriously wrong with that car. Radio message advises him the issue was just a de-rate, and nothing of consequence.

"There's something weird with the engine up the hill" says Antonelli.

Replay shows Russell putting his left-front on the white line at the pit exit as Piastri is confirmed as a 5s penalty.

That's Numberwang!

Piastri now under investigation for pitlane speeding.

Sainz into the pits at the end of lap 53. Let's see where he feeds out... just ahead of Albon!

Job done for Williams. Well, nearly - now Sainz has to create a big enough gap to hand that spot back.

So, Russell now 75s behind his teammate so not far off being lapped. Ordinarily we'd consult the GPS to see exactly how far off, but it's not working on our data feed today.

Colapinto penalised 5s for pitlane speeding... and now Gasly too. There's been a rash of these, so no doubt there will also be some complaints at the end of the race.

Gasly now being examined for pitlane speeding.

After that excitement at the tail end of the top 10, let's check in with the leaders. Antonelli now 22s ahead of Hamilton, who of course is carrying a 5s penalty. Leclerc now within that window, 4.818s behind his teammate.

Pause for 46s... aaaand that's Russell in P4.

Ah, replay indicates Albon straightlined the chicane so it's likely he was instructed to let Lindblad by.

Perhaps Albon was too busy thumbing his radio button because, as lap 50 begins, Lindblad mugs him for P10.

Albon still not happy with the strategy, suggesting it's too effing clever.

The chafing club behind Albon comprises Lindblad, Hulkenberg, Ocon, Colapinto and now Alonso.
