When you talk of Michael Phelps, when you talk of Ian Thorpe, you are now going to have to talk about Leon Marchand because that is one of the best things I think we have ever seen.

The fans in this arena are just trying to breathe this in, to appreciate it. They have been at a night where history has been made. We are watching the birth of a phenomenal, world class, Olympic swimmer.

The French fans don't want to go home.

Leon Marchand's arms are aloft in the air and he is milking it, rightly so.

He has taken on two specialists - the greatest butterflier that has ever lived, Kristof Milak and then Zac Stubblety-Cook - he beats them both.

I feel lucky to be here tonight.

I cannot believe he has beaten the specialists on those disciplines on the same night. I wouldn't believe it would be possible to do in three days apart nevermind two hours apart!

George Thorpe: Is Marchand French for fish?

Paul Snowdon: Leon Marchand!!! Wow! Wow!! Wow!!! A history-maker!!!

Lowri Green: Time to change the lyrics to La Marseillaise to Marchand, Marchand!?!

Leon Marchand is back on the top of the podium with a gold medal around his neck for the second time tonight.

They'll have to start charging him rent soon.

He really is a superstar and that's clear to see when a roar rings around the arena.

This rendition of La Marseillaise is going to be special.

There is only one word for that from Pan Zhanle: Ridiculous! Absolutely ridiculous. There has been so much talk of a 'slow pool' and I just want to know how quick that would have been in a 'fast pool.' That was unreal.

You don't win a 100m freestyle by a body length. That was just outstanding from Pan Zhanle. The crowd is stunned. He has been a bit hit and miss at this meet, came 22nd on the 200m freestyle, did the relay. 46.40 on the freestyle in a 'slow' pool.

That gold for Pan Zhanle takes China back to the top of the medal table at Paris 2024, knocking hosts France down to second.

China have 19 medals overall with France boasting 26 but China have nine golds to France's eight.

Pan Zhanle rattled it last year at the Asian Games and he looked great in the relay.

He destroyed the field in that race.

Despite having six points deducted for spying on a rival team's training session - something which led to coach Bev Priestman being banned for one year - Canada are closing in on qualifying for the quarter-finals.

They won their first two matches and currently lead Colombia 1-0 with 10 minutes or so to go. If the results stay as they are, Canada would advance as runners-up.

Pan Zhanle is out quickly and leads after 50m.

We'll be hearing and seeing more of Leon Marchand but no time to dwell.

It's over to the last final of the night.

Who will prevail in the 100m freestyle?

Romania's David Popovici and China's Pan Zhanle are strong contenders.

Leon Marchand has done the unthinkable, he's done the double. A double Olympic champion in one session. Not even Michael Phelps tried that. The audacity. 200m butterfly and 200m breaststroke, I cannot believe he even tried it, never mind won them both.

Australia's Zac Stubblety-Cook wins silver with Caspar Corbeau of the Netherlands taking bronze.

It's a new Olympic record of 2:05.85 seconds set by gold medallist Leon Marchand.

Pressure? What pressure?

Marchand takes it all in his stride and he's only 22!

That was extraordinary and now Leon Marchand can celebrate. What a special moment this is.

Experts, external reckon no-one has won two golds in a night at the swimming since 1976.

Before that it was 1900, when one of the golds was the 200m obstacle course.

The roof comes off the arena! What have we just witnessed? We have just witnessed Olympic history.

Leon Marchand is going to lead this down and use his speed. Zac Stubblety-Cook has got to sit there, his technique does not allow him to go out as fast. He has to have nerves of steel to just sit on Marchand and then hit later on.
