Here comes Harry Charles on Romeo 88 for Team GB.

He racks up eight faults which puts Team GB on 24 with gold medalist Ben Maher still to come.

400m to go! Joe Choong is back in first!

Uh-oh. Egypt's Ahmed Elgendy has taken the lead with 800m of running to go!

Joe Choong has got to go up another gear!

GB's Joe Choong is still in the lead as we go through the third range.

The chasing pack is now a group of four. They haven't closed the gap on Choong by much. He retains an eight-second lead.

This was the standings after four rounds.

Will Joe Choong remain at the top after this final laser-run event? He's looking good so far.

Joe Choong leads and looks composed. You can see he's starting to think about the shoot, just wiping the sweat from his eyes.

That was incredible shooting by the Briton as he is out of the range and putting pressure on the chasers

Amazing shooting from Joe Choong! He flies out of the second range. GB's James Cooke is going along nicely too.

Joe Choong looks in control at the early stage. He's kept the gap after the first shoot and is through the 400m mark.

He's halfway through the first run.

It's a fourth clear round in four days for Henrik von Eckermann on King Edward.

With a time of 78.05, that puts Sweden in front of the USA after the first round in the showjumping team final.

Just 1.28 between them.

The laser run involves cross country running and laser pistol shooting in multiple sequences.

Each competitor runs four 800m laps with four series of hitting five targets with an unlimited number of shots in a maximum time of 50 seconds on a target.

The laser run is up next in the men's modern pentathlon and Great Britain's Joe Choong has a 12-second lead.

It's the final event of the competition so he's going for gold.

Compatriot James Cooke is down in ninth but also in a strong position to challenge for a medal.

Also coming up later is the women's 10,000m final. That's due to start around 11:45 BST.

Sifan Hassan is looking to pick up another medal after winning gold in the 5000m and bronze in the 1500m.

The flying Dutchwoman did the 1,500m-10,000m double at the World Championships in Doha.

She also set the 10,000m world record earlier this year but it only lasted a matter of days before Letesenbet Gidey of Ethiopia broke it.

Gidey, 23, will be her biggest rival later today too - she won world silver behind Hassan in Doha.

It's a great start for the USA. Laura Kraut on Baloutinue produces the first clear round to put them in gold medal position as it stands.

The Rio 2016 silver medallists look like they mean business in Tokyo, but still a long way to go here.

The women's high jump final gets under way shortly, with involvement from Great Britain's Morgan Lake.

Three-time reigning world champion Mariya Lasitskene had been struggling for form in 2021 but her first 2m clearance of the year in July was well timed.

She will start as favourite along with Ukraine’s Yaroslava Mahuchikh. The 19-year-old won silver behind Lasitskene in Doha, claimed European indoor gold in March and tops the world lists both indoors and outdoors in 2021.

Lake, who is expected to be the 12th athlete to jump, appears in her second Olympic final after recording a personal best to qualify.

Holly Smith and Denver have been saved for this competition.

In the middle part of that combination of a very difficult tight stride, the horse just took his eye off it and they also went into the water on the next part.

Unfortunately, it all just fell apart. They finished under the time but with 16 faults.

Holly Smith is first up for Team GB on Denver and it's not a great start.

16 faults gives Great Britain a mountain to climb in this team event final.

The starting order for the showjumping team final is the reverse of the rankings in the team qualifier – but after the first two athletes from each team have competed, there is a 20-minute break during which an intermediate (as-it-stands) classification of the teams is established.

This is used to determine the starting order of each team’s third athlete, which will be in reverse order of their team’s intermediate ranking. In case of a tie on penalties among teams which have completed the initial round without any team.

A team’s score is calculated by adding together the penalties incurred by its three athletes. If there is a tie on penalties for the gold medal, there will be a jump-off against the clock involving all three of the team’s riders.

Racky: I have to say I wasnt expecting to watch a lot of Tokyo Olympics but I have really enjoyed it. Fantastic displays from all competitors from all nations.

Craig: Beautiful words from Tom Daley after receiving his Bronze Medal today. Family is everything, past & present.
