Josh Kerr's time was a season's best of 3:29.38 and he finishes more than two tenths of a second clear of Norway's Jakob Ingebrigtsen in 3:29.65, with another Norwegian, Narve Gilje Nordas, taking the bronze in 3:29.68.

IT'S HAPPENED AGAIN!

It's Kerr v Ingebrigtsen.

Josh Kerr hits the front.

Britain's Josh Kerr second and on Ingebrigtsen's shoulder as the bell sounds. Chance of a British medal here.

Abel Kipsang of Kenya leads after the first lap, before event favourite Norway's Jakob Ingebrigtsen moves to the front. He's trying to pull clear.

And here we go.

When Josh Kerr won Olympic bronze in 2021, he became the first British man to win a medal over 1500m at a Games since 1988.

Tonight, he's hoping to become the first British man to win the world title since (*checks notes*)... last year.

Jake Wightman, the reigning champion for just a little while longer, is watching on from the BBC studio.

In his absence, Jakob Ingebrigtsen is the clear favourite - but Kerr said before the championships that he felt the Norwegian star was "very beatable". He's not just aiming for the podium here.

Still to come on the track the men's 1500m final, the women's 400m final and the men's 400m hurdles final.

Australia's Nina Kennedy and America's Katie Moon are the only two left in the women's pole vault.

They are tied first at the moment, having both cleared 4.85m first time around, but failing at 4.9m with their first attempts.

Any clearance now could be the difference between gold and silver.

Watch as Great Britain's Josh Kerr and Neil Gourley reach the men's 1500m final at the World Athletics Championships alongside Jakob Ingebrigtsen. (UK only)

Fifth in the world for Molly Caudery. She should be so proud of herself and not only because she's come and competed and brought her personal best at the biggest stage but because she barely had a winter to train off of.

She got surgery this winter and was rehabbing for half the time. It wasn't really part of the plan to compete at these World Championships. It was a surprise that she qualified outright. She's been dealing with a minor calf issue too.

Well done Molly Caudery. You can't ask for much more than a personal best, can you?

At 23, contesting her first global final, the future looks very bright indeed for the Commonwealth silver medallist.

She's had great fun out there and can't stop smiling as her competition comes to an end.

There is to be no medal for Britain's Molly Caudery as she fails her two attempts at 4.85m, after passing 4.8m after her first go.

Nevertheless, she still smashed her personal best, which had been 4.71m, to clear 4.75m and finish fifth. Plenty of reasons to be very happy with her evening's work.

More from last year's 1500m world champion Jake Wightman.

Can anybody beat Jakob Ingebrigtsen tonight?

"What my victory showed is that Jakob Ingebrigtsen is beatable. The British guys (Josh Kerr and Neil Gourley) have beaten me so there's every reason they can go out and beat Ingebrigtsen tonight.

"Everybody knows how to beat someone like Ingebrigtsen. It's one thing knowing how to do it and another him giving you the opportunity to do that.

"You have to get past him at some point in the race because you need to cross the finish line first but he won't let that lead slip in the last lap. So I hope that somebody, not necessarily the British guys, will try to disrupt him.

"I'm sure we'll see Kerr and Gourley make a statement on the race to try to win. You don't want to be a passenger in a race like this."

Reigning world 1500m champion Jake Wightman, who can't defend his title because of injury, speaking on 5 Live Drive.

Have you watched back your 1500m win at the 2022 World Athletics Championships?

I've had a year of a lot of injury struggles so it's nice to watch it to give yourself a little bit of motivation as to why you're still grinding away when stuff isn't going quite as well. It's a nice moment, one I'll never ever forget.

How is your recovery going?

It's been good. I'm finding the place now where my body is in a good place. It's in one piece and ready to attack a winter. I just ran out of time to get myself in the fitness I needed to, to get ready to be able to defend my title which was disappointing but also relieving because I had been battling the timeframe of Budapest for a while.

"To finally know I wasn't going to be able to come back was obviously very disappointing but it meant I could take the time I needed to get myself fixed up ready for winter and hopefully ready for an Olympics next year.

With British reigning champion Jake Wightman injured, can anyone prevent Jakob Ingebrigtsen winning his first 1500m world title?

Plenty of runners – Britain’s Olympic bronze medallist Josh Kerr, Neil Gourley, Kenya’s Abel Kipsang and American Yared Nuguse among them – will fancy their medal chances.

However, Norway’s Ingebrigtsen is unbeaten since losing out to Wightman last summer and has set European 1500m and world 5,000m records in recent months.

Earlier this year, he said his “main goal is to become the best runner that ever existed”. Gold here would help him on his way to that lofty aim.

It's going to be a very exciting final, there's no doubt about it.

Puerto Rico's Jasmine Camacho-Quinn finishes strongly to take the third semi-final, winning in 12.41 with American Nia Ali coming second in 12.49.

But it is good news too for Jamaica's Danielle Williams as her season's best of 12.50 sees her nudge out fellow Jamaican Megan Tapper from the first semi-final and qualify as one of the two fastest losers, along with Ditaji Kambundji of Switzerland.
