It has been a very shaky start to the pole vault for defending champion Katerina Stefanidi.

She has needed all three attempts at both of the opening heights, but makes it over 4.70m to stay in the hunt. Nine athletes are already out.

Kerr finishing fast and he will go through.

Heyward just taking sixth place and just looking at the time - a new Olympic record from Kipsang so that might augur well for Heyward to be fast enough.

A fast start from Jake Heyward, dashing to the front before Norway's Jakob Ingebrigtsen takes charge alongside Australia's Stewart McSweyn.

The Australian strides clear of the pack and then Abel Kipsang starts to come through on the bell, but Heyward and Josh Kerr are also in the mix.

Can they kick on into a qualification place? A top-five place will definitely do it, Kerr places third to make it and Heyward also progresses as a fastest loser after finishing sixth.

That's three Brits in the final of the men's 1500m.

Meanwhile, Kipsang has set an Olympic record of 3:31:65!

More British interest in the second semi-final, with Jake Heyward and Josh Kerr.

Can they join Jake Wightman in the final? We'll find out in under four minutes' time...

Australia are level in the fourth quarter of the men's hockey final, making it 1-1 against Belgium.

The ball bobbles around the area - Aran Zalewski sends it goal-bound and Tom Wickham touches the ball down into the net.

Holly Bradshaw is only the second athlete to go clear at this new height of 4.70m.

She just has to stay focused as so many of the other contenders are struggling all around her.

Excellent work from Great Britain's Holly Bradshaw.

She failed her first attempt at 4.70m, but nails the second as her coach puts his hand over his heart in the stands.

She is the second athlete to clear that height, with some of the gold medal contenders struggling in the early stages.

Jake Wightman strikes for home - brilliant from him, excellent performance.

Made no mistakes and perfectly judged that race. Tactically he's very good and when he's fit and healthy as well, he puts races together like that.

A really tricky race this one, but Jake Wightman is hanging on the shoulder of Kenya's Timothy Cheruiyot and then makes his move around the final bend!

The Brit storms clear down the straight and wins his heat in 3:33.48. Superb run.

Team GB

More from the Team GB Women's 4x400m team after they qualified for the final.

Zoey Clarke: "We were really trying our best to get ourselves in the top three positions so we pushed ourselves really hard. Bit tricky on the home straight but we did it."

Laviai Nielsen: "It feels like we’ve been in Japan for ages and we’ve managed to come together as a team and hang out as a team in the holding camp and here. We’ve got an incredibly close knit team and we’ve got Jodie (Williams) in the finals who ran amazing yesterday so just wanted to get us in a good position and hope we bring more to the final."

Nicole Yeargin: "I wanted to bring it home and make sure we got that big Q."

Great Britain's Jake Wightman is up in the first of the men's 1500m semi-finals. And away he goes in Tokyo...

Geoff Wightman and Katharine Merry are doing a sterling job calling the action as the stadium announcers in Tokyo.

As Geoff reminded Katharine, he will be paying a little more attention than usual to one of the events.

His son Jake is up against world champion TImothy Cheruiyot in a tough first semi-final at 12:00 BST. The top five in each semi-final and two fastest losers from across the two races advance to the final on Saturday.

Great Britain's Holly Bradshaw fails with her first attempt at 4.70, in fact Russian Anzhelika Sidorova is the only athlete to do so in the competition so far.

A nervy final so far.

It was fantastic to see Keely Hodgkinson in the 800m yesterday, she brought it home and raised our mood bringing that first silver medal.

That gave us such great hope but there's definitely a question about where the other medals are going to come from.

We've had a situation that is out of our control with injuries to KJT and Dina Asher Smith - we need to see how many other medals we can sneak at this Olympic Games.

It has been a different Games than we all expected but we have to take the last year into account.

Questions are being asked of some of the favourites - Katie Nageotte and Katerina Stefanidi - and they are contenders.

Well - this really bodes well for Britain's Holly Bradshaw.

First blood to Belgium at the start of the third quarter of the men's hockey decider.

A really good move is poked in at the far post by Florent van Aubel for his second goal of the tournament.

One feels more achievable than the other but I have still failed on both fronts...

However, here's a joke for you: How do you get 100 Pikachus on a bus? Pokemon!

We're still waiting for the opening goal in the men's hockey final with the second half just starting.

There's been plenty of action and drama so far. There's no extra time so if it is level after 60 minutes, it goes to penalties.

All five teams are going to go through. It was very close. The Dutch have a new national record, they will go through with the Canadians too.

GB automatically qualify in third.
