What a semi-final race from Gretchen Walsh.

The American just misses out on her own world record, but she sets a new Olympic record with a time of 55.38 seconds.

Germany's Angelina Koehler finishes second, while Mizuki Hirai is third.

Great Britain's Keanna Macinnes comes in eighth.

It goes without saying the cheers for the French swimmer in this first semi-final was huge. But there were was a lot of noise made by Australian and American fans as the swimmers emerged.

I can see Stars and Stripes over to my left. There are Go Aussie Go signs below me.

This is going to be a wild night.

Tokyo was a fantastic Games for Team GB swimmers and I could really see us backing that up here in Paris.

We have medal hopes all over the place, we have such depth in our relays as well. We have Adam Peaty too and there's always medals when you have Adam Peaty.

Vamos!

A trademark Nadal winner goes racing away, and the first set has gone the way of Nadalcaraz.

If anything, that set showed how tricky it is for singles players to play specialist doubles players - there were times that Alcaraz looked as though he had forgotten there were two people on the other side of the net - but the Spanish duo have come through it well.

Ian Graves: The swimming events at the Olympics are always good value. Lots of British talent to cheer for.

Well, I have just lost my last fiver... (see 6:46pm entry).

France were a force of nature tonight - and that force was called Antoine Dupont.

France were already playing well against the favourites Fiji, but the X factor from Dupont tipped the match in their favour.

Incredible to watch.

Great Britain's Charley Davison is out of the bantamweight contest after being beaten - via a 3:2 split decision - by Hatice Akbas.

The 30-year-old, who said this would be her last Olympic Games before competing in Paris, lost the opening round before picking up form in the second. But it was not enough to overcome Turkey's 2022 world champion and she will not progress.

You can watch the fight highlights on iPlayer and the red button after the tennis concludes, with some eventing action to follow - and a very special dressage routine from Great Britain's Laura Collett.

UK users can choose from two television streams plus live radio coverage in the watch & listen tab (next to the live reporting tab) on this page.

The music has been booming inside the La Defense Arena but now the lights have gone out, a harpist is playing and the pool is being lit up like a Monet painting.

Beautiful.

Adam Peaty isn't the only Briton in action in the pool this evening.

James Wilby will feature alongside him in the 100m breaststroke semi-final (20:15 BST) after qualifying in sixth.

But it's GB's Keanna Macinnes who is up first after she qualified for the semi-finals of the women's 100m butterfly (19:30).

Both Team GB's men and women are also through to the 4x100m freestyle relay final.

Adam Peaty began his pursuit of a third consecutive 100m breaststroke Olympic gold medal by powering through to the semi-finals.

The 29-year-old won his race in 59.18 seconds to qualify with the second-fastest time of the heats.

The Briton, who broke the world record in the event in 2019 with a 56.88 swim, has taken time out in recent years to deal with periods of depression and alcohol problems.

His return to sport's biggest stage has been long anticipated and he can take one step towards defending his gold medal in tonight's semi-finals, which are coming up very shortly.

After that rugby drama, the focus switches on BBC One to swimming, while there's tennis on iPlayer and the red button.

Andrew Priestley: Antoine Dupont may just have taken a massive step towards cementing himself as the greatest rugby player of all time by the time he retires. He’s the world’s best in the XV-man game & now has added a home Games gold medal in the Sevens. That CV will be hard to match.

France fully deserve it - what a performance.

That was the best team performance we have seen in this tournament so far, they saved their best until last. They have outclassed Fiji.

Antoine Dupont, take a bow.

Great Britain's Charley Davison lost the opening round of her bantamweight preliminary against Turkey’s Hatice Akbas but has since come back to take the second.

One deciding round for a place in the next phase.

Woweee! This French team who didn't qualify in Tokyo 2020 are now glorified in Paris. With 70,000 here and millions watching around the world. An incredible journey. This moment will go down as one of the greatest in French rugby.

The whole crowd have been waiting for that one - Dupont going over that line and he has.

He has come on and just lifted this French side. Everything that has been good about France in this second-half, he has been involved in.

That was just brilliant - great patient build-up and a great try.

I wonder why there was just a massive, spontaneous cheer and a lot of French flags flying at Roland Garros...

No wonder French President Emmanuel Macron is delighted. France have their first gold of the Games.
