Lovely start from Leon Marchand.

I said all along I thought this race was Leon Marchand's. He looked so good in the semi-final yesterday, his breaststroke is so fluid and smooth. It is just about how he is able to recover from his earlier win.

All eyes on the middle of the pool.

Leon Marchand will go in lane four with Zac Stubblety-Cook in lane five.

"LE-ON! LE-ON! LE-ON!"

The crowd are already ramping up the atmosphere.

Their man is about to step out again.

No-one in history has completed the 200m butterfly-breaststroke double.

France's Leon Marchand is attempting to change that in just a few minutes.

He wrapped up gold in the 200m butterfly earlier, beating Hungary's world and Olympic record holder Kristof Malik.

Next up is the 200m breaststroke, can he close out the night with another gold?

Hit the thumbs!

Thumbs if you think he can win another gold, or thumbs down if you don't think he can do it!

We've got two swimming finals coming up on BBC One over the next 20 minutes but if that's not your thing then you can always switch over to iPlayer and watch some of the top NBA players in action.

It's Team USA v South Sudan in the basketball.

Ready for the roof to come off again?

France's Leon Marchand is due back to the pool at 21:31 BST with a second gold of the night in his sights.

Olympic record holder Zac Stubblety-Cook of Australia won gold at Tokyo 2020 and looks set to be his biggest rival.

Team USA's Kate Douglass wins the second semi-final in a time of 2:19.74 seconds - a much quicker pace than Tes Schouten of the Netherlands, who won the first semi in 2:22.74 seconds.

South Africa's Tatjana Smith is second.

Team Ireland's Mona McSharry finishes sixth and her time of 2:24.48 seconds is only good enough for 11th overall, so she won't be in the final.

After taking bronze in the 100m breaststroke final, Team Ireland's Mona McSharry has her sights set on another final but this time in the breaststroke over 200m.

She has been handed a tough semi-final with South Africa's Tatjana Smith, Olympic record holder, for company.

Tes Schouten of the Netherlands is quickest in the first semi-final - 0.13 seconds clear of South Africa's Kaylene Corbett.

Female boxer Cindy Ngamba came out on top against Tammara Thibeault earlier today. Ngamba is part of the Refugee Olympic Team and resides in Bolton, Lancashire.

Ngamba has been training alongside Team GB during her preparation for the Games. 2020 Olympic gold medalist Galal Yafai told, BBC Radio 5 Live, "Cindy is massively a part of Team GB,"

"I train with them everyday and she is a part of Team GB as much as anyone."

Team GB's boxer Lewis Richardson speaking to BBC Radio 5 Live added: "Her story will get told worldwide. I cannot wait to watch her film one day."

Team GB boxer Lewis Richardson, speaking to BBC Radio 5 Live: "Over the moon to get the first one out the way, people are aware that it has been a difficult time for GB boxing.

"Extremely close decision and another one there, but I got the rub of the green. Extremely proud and grateful, fresh and ready to go.

"I felt like I won the fight, but the scorecard suggests it was close. We have seen results not go our way, but I am grateful to get the decision go my way on that one. We have had a tough draw and we have all boxed medallists - every single one of us.

"It is testament to how difficult the Olympic cycle is and I am one fight away from winning an Olympic medal.

"We broke the curse, I have been waiting around a good few days and didn't see decisions go our way. Testament to myself for staying focused - I lost the first round and struck to my game-plan."

Great Britain's Lewis Richardson beat Serbia's Vakhid Abbasov by a 3-2 decision.

GB have struggled in the boxing ring this Games and five of their six boxers had lost before Richardson took to the ring.

Richardson, 27, was not picked for the delayed Tokyo Games in 2021 - he is now GB's only hope of a medal in the boxing ring.

The final bouts will now take place at the Roland-Garros stadium.

Roman Mityukov of Switzerland is quickest in the second semi-final.

He's 0.9 seconds slower than Hungary's Hubert Kos, who won the previous semi.

Confirmation that Team GB's Oliver Morgan will not be in the final. He 12th fastest overall - only the top eight times advance.

Team USA may be seventh in the official Olympic medal table, but that means nothing to their patriotic media organisations who organise the medal table by medals won, not golds won as is standard.

Just one example above from host broadcaster NBC.

Hungary's Hubert Kos wins the first semi-final with Italy's Thomas Ceccon, who took gold in the 100m backstroke, in fourth.

Oliver Morgan of Team GB finished sixth. His time of 1:57.28 seconds might not be enough to reach the final.

Team GB's Oliver Morgan came last in the men's 100m backstroke final on Monday but he's back to try and reach another one in the 200m.

He appears in the first semi-final and faces some serious medal contenders with Italy's Thomas Ceccon, who took gold in the 100m backstroke, heavily fancied to set the pace.

The United States, managed by former Chelsea boss Emma Hayes, have gained their third win in three matches to progress into the quarter-finals with a 100% record and as group winners.

They beat Australia 2-1 earlier on to win Group B, while Germany gained a routine 4-1 victory over Zambia to join them in the next phase.

Hosts France are drawing 1-1 with New Zealand at half time, with it being goalless in the game between Colombia and Canada.

A win for Canada could see them qualifying, despite them having six points deducted after a drone was flown over the training session of group rivals New Zealand before the Games started.

Sarah Sjoestroem has just stood atop of the podium to receive her gold medal - it's Sweden's first at Paris 2024.

Sjoestroem is no stranger to that position, though, after taking gold in the 100m butterfly at Rio 2016.
