Next up is the women's 1500m freestyle final with American Katie Ledecky looking for a 12th Olympic medal and hoping to defend the title she won at Tokyo 2020.

Off they go...

The rule is that you have to have your head above the surface before the 15 metre line. Luke Greenbank is slightly near the surface at the line and it just comes up there but his head is not fully above the water until a litle bit later. It was quite a a bit over the limit, so they did not contest it.

He is so excited to race that he probably didn't realise. It is a different venue to what you expect at the Olympic Games too, a temporary venue, the lights, the setup may be different to what he is used to.

Gripped by the swimming?

You can keep across all the action on BBC One.

If you missed any of the morning session, here's one of the more dramatic scenes when Team GBs Luke Greenbank was disqualified in the men's 200m backstroke.

Watch that incident below.

FINALLY. It’s a win for the red corner and Lewis Richardson.

He wins on a split decision 3-2 and is absolutely chuffed.

GB continue in the boxing.

Get in.

In that last round he won in three of the cards, that is all he needed to do. That was magnificent and I am so pleased for him, he deserved that - we deserved some justice today.

For the first time in six days we are going to speak to a British [boxing] winner.

The victory was all in the turn from Leon Marchand. The 50 metres off the wall was the deal. Tactically Marchand will have known that Kristof Milak likes to lead from the front, he did that in the heats and the semis, so just sit on him then pounce. It was Michael Phelps-esque in that final 50 metres.

After the other five fighters in the Team GB camp have all fought and lost, Lewis Richardson keeps the hopes alive, with a tense and tight win over Vakhid Abbasov of Serbia.

Richardson produced some clean shots in that deciding round and he squeaks through 3-2 in a split decision. The rest of Team GB are bouncing around in the stands in delight.

GB get their first win in the boxing ring in Paris 2024.

You can hear the rumble of the crowd, everyone is ready for a big final round.

This is neck and neck after the first two rounds.

Kristof Milak looked fantastic in the semi-finals, and it was always going to be head to head battle between him and Leon Marchand. That last 50m from the Frenchman was unbelievable.

Lewis Richardson has got to go for it he cannot lose over a small margin, you cannot cry over spilt milk. He has got to go for it now.

Lewis Richardson is the last member of Team GB left in the boxing event and after losing the opening round on three of the five scorecards, he needs an improved second round to have any chance.

He gets it, just with three of the judges going for him and two against in round two.

"Don't let him push you back," Richardson is told.

All square, GB's boxing hopes could be ended in the next three minutes.

Phewf. Everyone is still catching their breath after that Marchand win. The schedule for these Games was altered to allow the Frenchman the chance of this double.

He's disappeared out of the stadium to try and recover for his second final (21:31 BST) as quickly as possible.

Great news for Team GBs Laura Stephens with her time of 2:07.53 seconds securing a place in the final.

It was the eighth fastest time of the two semis with only eight advancing.

Team-mate Keanna Macinnes does not make it, though.

Another day, another flurry of medals. Here's a recap of today's action so far.

• After a thrilling finish in the triathlon, Alex Yee won the gold medal for Team GB (see video above). In the women's race, Beth Potter won bronze.
• Meanwhile, there was also rowing gold for Lauren Henry, Lola Anderson, Hannah Scott and Georgina Brayshaw in the women's quadruple sculls. That came after a dramatic photo finish.
• There was silver for Kieran Reilly in the men's BMX in a thrilling final.
• And it was diving bronze for Andrea Spendolini-Sirieix and Lois Toulson, who triumphed in the women's synchronised 10m platform.
• In the women's hockey,Hannah French scored the winning goal as Great Britain boosted their chances of progression with a 2-1 victory over South Africa.
• GB's world champion Mallory Franklin struggle in the final of the canoe single final, where she was unable to emulate her silver medal from Tokyo.
• And it was so near yet so far for GB's gymnasts as Joe Fraser finished fifth with Jake Jarman seventh (see highlights of one of his routines below).

Team USA's Alex Shackell leads with 50m to go but China's Zhang Yufei is not letting this go without a fight, it's going to be so tight.

Zhang takes it.

Shackell is second and Australia's Abbey Connor is third.

Britain's Lewis Richardson thinks he has done enough to win a tight and cagey opening round. Three of the five judges disagree and give it to the Serb fighter.

Lewis Richardson cannot do his work in close, his arms and knees are too short - he has to keep it long.

We know there are four strokes in swimming but effectively the fifth one is turns. If you can get a good technique, to get a big fly kick under the water, then you can get some good distance on it. The good swimmers turn well.

Zhang Yufei is been reeled in slightly with Australia's Abbey Connor and American Alex Shackell coming into it.

Zhang Yufei of China is off to a flyer and already almost a full body length clear at 50m.
