GB's Charlie Dobson speaking to BBC Sport after finishing sixth: "I mean there was quite a decent gap to fifth, unfortunately we just weren't in a position to fight for anything.

"But I want to say a massive thank you to our sponsors - they've been a massive help for us getting here and we will definitely be back and one day get that medal."

GB's Lewis Davey speaking to BBC Sport after finishing sixth: "It is [a well drilled unit] and we practice a lot so we have a good group of lads and we don't really have an excuse. It wasn't great with the conditions but I thought that was absolutely dreadful.

"I don't know about the other lads but my running felt absolutely dreadful."

The women's high jump final is back under way, with six athletes still in medal contention.

Australia's Nicola Olyslagers, who completed her jump before the rain delay, is the only person to clear 2m so far, doing so at the first attempt.

However, the men's discus final is yet to restart.

The final event in the men's decathlon - the 1500m - gets under way at 12:49.

Germany's Leo Neugebauer leads the way with 8072 points. USA's Kyle Garland (8057 points) and Puerto Rico's Ayden Owens-Delerme (7958 points) in the other medal positions.

One of the greatest competitors in modern athletics, Shelly-Ann Fraser-Pryce, has been confirmed as running the first leg for Jamaica in the women's 4x100m.

This will be Fraser-Pryce's final race before retirement.

For GB, as expected, 200m silver medallist Amy Hunt will run the second leg in place of Success Eduan, who ran in the heats.

Hunt will join Dina Asher-Smith, Desiree Henry and Daryll Neita for the final at 13.10 BST - in Britain's final chance for gold at these championships.

Heading into the final lap, USA are still in first place. Gold is looking very secure.

Jamaica are second but the Netherlands' Femke Bol is chasing them down.

At the halfway mark, USA are streaking ahead.

Jamaica, Netherlands and Belgium are battling for the other medals.

Netherlands' Eveline Saalberg looked a little tentative on that first lap but it's understandable in these wet conditions.

After the first change, USA, Jamaica and Netherlands are in the medal positions.

The rain has relented somewhat as the women's 4x400m gets under way. Can Netherlands defend their crown?

No GB team in this one after they finished last in their heat - but there is some tangential British interest.

Isabelle Black, daughter of 1991 4x400m gold medal winner Roger Black, ran the third leg for France in the heats to help them earn a spot in the final.

Olympic champions USA will start as favourites after setting a world lead time in the heats, and could call on individual world champion Sydney McLaughlin-Lavrone.

Netherlands and Jamaica, the top two in the 2023 World Championships, will likely provide the sternest challenge.

Great Britain's Lee Thompson speaking to BBC Sport after finishing 6th: "We wanted to come here and get a medal. We knew that was possible,

"We've always had a couple injuries in the squad but everyone stepped up. We just got high expectations now coming off a couple years where we've been medalling.

"We need to get back in the medals and we'll do that from next year and onwards."

The women's high jump final and men's discus final have been suspended because of the rain but are expected to resume in the next 10 minutes.

The track is being mopped before f the women's 4x400m final.

Looking at that race, we thought George would have the leg speed at the end. George has had a big breakthrough this year with that British record but something was not right out there.

Who would have thought a few years ago that Botswana would be a world power in men's athletics?

Their relay celebrate with a knees-up - literally - on track after winning in 2:57.76.

USA beat South Africa to silver by two-thousandths of a second.

A stunning final 100m, and Collen Kebinatshipi catches 400m hurdles champion Rai Benjamin right on the line!

South Africa take the bronze, while GB finish sixth.
