GB win first medal as Dutch stumble, Hughes breezes through 100m heat
21:45 BST - And that's a wrap for today! Thanks for joining me on a thrilling opening to the 2023 World Athletics Championships in Budapest.
We'll be back for more tomorrow!
21:26 BST - Katarina Johnson-Thompson is set for a huge final three events on Sunday..
21:09 BST - Amid all the excitement there's dejection for Lawrence Okoye (see 19:25) who loses out on a place in the discus final by a mere 13cm.
Germany's newly crowned national champion Henrik Janssen takes the final qualification spot with a throw of 63.79.
"I just didn’t really give myself an opportunity to get a massive throw out there," Okoye told reporters before he knew of his elimination. "I started so poorly in the first couple of rounds, so the third round I had to do a safety throw."
As it turns out, that final safety fell agonisingly short.
20:52 BST - GB win silver in the mixed 4x400m relay! It is their first medal of the 2023 championships as USA win gold in a world record time of 3:08.80.
GB were heading for bronze in a frantic dash to the line as USA's Alexis Holmes and Netherlands' Femke Bol battled neck-and-neck for gold and silver. With just two metres to go Bol stumbled, losing control of the batton and hit the deck, allowing Yemi Mary John to take second place.
It is the second race in a row where a Dutch athlete has lost control of a race yards from the finish. Heartbreak.
20:50 BST - And we're off!
20:45 BST - We now move to the last event of the day - the final of the mixed 4x400m relay. GB in lane eight have made one change to their record-breaking heat with Lewis Davey replacing Joe Brier. Laviai Nielsen, Rio Mitcham and Yemi Mary John complete the line-up.
Ireland, in lane two, remain unchanged: Jack Raftery, Sophie Becker, Christopher O'Donnell and Sharlene Mawdsley.
Can Britain or Ireland win their first medal of the championship? They will face very tough competition from USA and Netherlands...
We're moments away.
20:39 BST - USA's double Olympic champion Ryan Crouser is now a double world champion! Leading the field from his very first throw of 22.63, Crouser smashed the shot put championship record with his last - 23.51 - sending the stadium into raptures. Incredible!
20:31 BST - A huge roar as they approach the final 200m and it's Gudaf Tsegay and Sifan Hassan battling it out for gold. They're in the final 100m but drama as Hassan's legs start to go and she falls to the ground about 20m from the finishing line! She crumples on the floor and looks utterly dejected as the field stream past.
Agony for Hassan - elation for new world champion Tsegay! It's also Gold, silver and bronze for Ethiopia with Letesenbet Gidey and Ejgayehu Taye completing the podium. Britain's Warner-Judd finished eighth.
However the largest cheer is reserved for Brazilian Maria Lucineida da Silva who crosses the line in 18th - almost five minutes later - to a standing ovation. Superb perseverance.
19:57 BST - It's the women's 10,000m final next up and all British hopes rest on Jessica Warner-Judd.
Warner-Judd faces an almighty challenge from Sifan Hassan, who is looking for the first of three golds in this championship, Ethiopian world record-holder and defending champion Letesenbet Gidey, and her teammate Gudaf Tsegay - world champion and Olympic bronze medallist in the 5,000m.
It's going to be a nervy 25 laps around the Budapest Athletics Centre... and we're off!
19:53 BST - And she's done it! Johnson Thompson stormed into the final 100m to win with a time of 23.48, putting her second in the overall rankings on 3905 points - 93 behind Hall.
We have a thrilling Sunday in store.
19:43 BST - Katarina Johnson Thompson is about to take part in the final heptathlon event of the day: the women's 200m.
The British star was ranked 10th overall leading into the event, and will need to assert herself over USA's Anna Hall and Germany's Sophie Weißenberg to stand any chance of medalling.
19:39 BST - Josh Kerr has been speaking after qualifying for the men's 1,500m and said he felt relaxed during the race. "I don’t know what the time was, but it felt smooth and we had some gears left in that last 100m.
"I made the moves when I needed to and I kept myself out of trouble so I am really pleased with it."
Neil Gourley, who also qualified, said: "That race went completely to plan!
"I need to be sharper than I was tonight in the semi-final. If I run tactically like I did today I won’t get a medal."
"Getting top six was the only thing I was concerned about today," said Elliot Giles, who completed the trio of British men qualifying for the semi-finals.
"I didn't panic on the backstraight even though I was a bit behind. A gap opened up and I made it through, so I did the job well. I knew if I did too much too early in that race, I would pay for it tomorrow (in the semis). I was patient and used my gears in the last 100m."
19.25 BST - Away from the 100m, Lawrence Okoye has finished sixth in the discus with a throw of 63.66 and faces a nervy delay to see if he qualifies. Okoye needs to wait until the conclusion of the second group, which gets underway at 19.43, to see if he comes inside the top 12.
19:21 BST - Olympic champion Marcell Jacobs set a season best 10.15 to qualify third in his heat on a photo finish, with Japan's Abdul Hakim Sani Brown winning on 10.07 - also an SB.
19:14 BST - A huge shock in heat five with Nigeria's Favour Oghene Tejiri Ashe disqualified for a false start. He looks utterly dejected but it's clear on review. Sweden's Henrik Larsson is then flagged for a false start on the second attempt, before they finally go on the third.
Jamaica's Oblique Seville sweeps aside any distraction to clock a personal best 9.86 ahead of the favourite, USA's double world champion Fred Kerley.
19:00 BST - The last British man in the 100m is up next. It's heat four featuring Reece Prescod. A huge cheer goes up for Hungary's Bence Boros. Will he cause an upset? They're off...
Prescod finishes third on 10.14 with Botswana's Letsile Tebogo pipping Rohan Browning on a photo finish. Boros finishes last, but to huge cheers.
18:53 BST - Can Britain's Eugene Amo-Dadzie follow Zharnel Hughes and reach the semi-final? Heat three is next...
Amo-Dadzie powers over the first 50m before slowing, allowing Netherlands' Raphael Bouju to beat him on the line via a photo finish.
18:45 BST - It's heat two and a huge cheer for USA's Noah Lyles. The three-time world champion and Olympic bronze medalist looks in sensational form - surely this is a formality?
It is! He clocks 9.95 to win the heat.
18:42 BST - It's the heats for the men's 100m with British record-holder Zharnel Hughes up first. What time will he clock here?
They get ready and they're off - and in a blink of an eye Hughes eases through, clocking 10:00, +0.01 ahead of Jamaica's Ryiem Forde on a photo finish.
Remember it's the first three who go through automatically, along with the next fastest three. It's a nervy wait in the holding area for those three...
18:37 BST - Katarina Johnson Thompson has just thrown her third and final discus a distance of 13.14m. It's not enough to beat her first attempt of 13.64m and finishes third. The 770 points earned means she drops to fifth in the overall rankings.
18:33 BST - A huge cheer erupts as they reach the final 100m as Kipsang pips Nuguse to the line with Australia's Adam Spencer completing the top three. Luxembourg's Charles Grethen sets a season best ahead of Elliot Giles who ensures all three Brits comfortably reach the semi-finals.
18:25 BST - Netherland's Niels Laros wins the third heat as Elliot Giles prepares for heat four. He'll be lining up against world number two and three - USA's Yared Nuguse and Abel Kipsang of Kenya. Kipsang set the 1,500m world record at Tokyo 2020 before it was broken by Ingebrigtsen in the final.
This will be tough - and they're off!
18:12 BST - Heat two and eyes will be on the world number six - Britain's Neil Gourley. They line-up, and pop - they're off!
This is a much slower and tactical race and the field is still bunched as they start their second lap.
Gourley is ninth as the bell rings for the final lap - who will move first? It's a 400m sprint and Spain's Mario García surged in the final 10m to win 3:46.77. South Africa's Tshepo Tshite comes from seventh to finish second with Neil Gourley third.
Remember it's the first six who go through.
18:08 BST - Jakob Ingebrigtsen wins the heat clocking 3:33.94, with Josh Kerr just under a second behind - but the front six had slowed long before the line, saving their energy for the final.
It's agony for Switzerland's Tom Elmer and Sweden's Emil Danielsson who tripped and fell to last on the penultimate lap.
18:04 BST - They're lining up in the first of four men's 1,500m heats. This features Britain's Josh Kerr alongside Olympic and world champion Jakob Ingebrigtsen of Norway. The gun goes and we're off!
18:00 BST - Ahead of the mixed 4x400m relay, Britain's Laviai Nielsen has been speaking to the media. He told reporters: "To run a national record shows us we're in really good shape to get a good medal tonight.
"We want to show that Great Britain is one of the strongest nations in the world. We've got such incredible strength in depth in all relays.
"We want to get back on that podium in mixed, women's and men's relays."
17:50 BST - Hello and welcome along to the evening session of the World Athletics Championships at the National Athletics Centre in Budapest.
The heats for the men's 1,500m will get us underway in just over ten minute's time with Josh Kerr, Neil Gourley and Elliot Giles looking to reach the semi-finals. Katarina Johnson-Thompson will resume in the heptathlon at 18:02 with Lawrence Okoye starting his bid in the men's discuss throw from 18:09.
Britain's Zharnel Hughes, Eugene Amo-Dadzie and Reece Prescod will look to qualify from the men's 100m heats before Jess Warner-Judd competes in the women's 10,000m final all before the history-making mixed relay team will contest their 4x400m final at 20:49.
As ever, we will bring you all the latest right here. Stay tuned!
14:50 BST - After a thrilling morning session attention turns to the evening with an opening ceremony getting us underway from 5pm.
Katarina Johnson-Thompson will be back in action and Zharnel Hughes will kick-start his world championship bid in the highly-anticipated men's 100m.
We will also find out whether Britain's 4x400m mixed relay team can turn their record-breaking qualifier into gold, with the final scheduled as the last event of the day.
14:33 BST - Britain's Jazmin Sawyers has failed to qualify in the long jump. The 29-year-old, who has been hampered with injuries in the lead-up to the championship, lept 6.41 to finish 22nd, with only the top ten progressing to the final.
"I know what I did wrong," she told reporters. "I haven't been able to do any jump sessions for a while. I was hoping I could work on it through the rounds, but I just didn't quite solve it in time.
"I don't want to stand here and make that excuse, it's not good enough. When you select a team as strong as this with the intention of top eight finishes, medal finishes, we should rise to that occasion as athletes and I've let a lot of people down, most of all myself. I really feel I've let myself down."
13:39 BST - Joining Laura Muir in the women's 1,500m semi-final will be Melissa Courtney-Bryant, who qualified with 4:03.14, and Katie Snowden, who crossed the line with a blistering time of 4:01.15.
However there's heartbreak for Ireland's Sophie O'Sullivan who failed to qualify despite setting a personal best time of 4:02.15 - that's quicker than Faith Kipyegon, who won the earlier heat, and her mother Sonia, who won the silver medal in the event in 1993.
Remarkably O'Sullivan's time was only quick enough for eighth place, with only the top six in each heat qualifying. Her time was also faster than teammate Ciara Mageean, who finished second in the last qualifier of the day.
13:24 BST - Johnson-Thompson fails at 1.89 and ends up finishing behind Weißenberg in second-place - enough for her to jump from 10th to fourth in the overall rankings with six events to go.
13:20 BST - Muir qualifies for the semi-final with ease as she crosses the line on 4:03.50, 0.58 seconds behind Sifan Hassan who will be bidding for three golds in Budapest.
At Tokyo 2020, Hassan became the first athlete to win medals in the 1,500m, 5,000m and 10,000m in a single Games. Can she repeat the feat at a world championship?
13:16 BST - Heat one of the women's 1,500m is underway and there is huge expectation on the shoulders of Brtain's Laura Muir. The first six in the heat will qualify for Sunday's semi-final.
13:14 BST - Incredible! Moments after Weißenberg sets a personal best at 1.86, up steps Johnson-Thompson to comfortably clear the same mark. The duo will battle it out for 1.89.
13:04 BST - Kate O'Connor will finish sixth in the high jump after failing to clear 1.83. Johnson-Thompson will be guaranteed at least 1016 points for attempting 1.86, but can she clear it? She's left competing alongside US pair Chari Hawkins and Anna Hall, as well as Germany's Sophie Weißenberg.
12:42 BST - Both Katarina Johnson-Thompson and Kate O'Connor are attempting 1.83 in the heptathlon high jump. O'Connor previously set a season's best at 1.80 - a distance Johnson-Thompson made at the third and final attempt.
12:21 BST - Scott Lincoln thew a personal best but failed to progress in the men's shot put. The 30-year-old threw 20.22 as he finished ninth and bowed out.
"It was shocking, It was just one of those days. The disappointment is pretty real right now," he said.
"I guess you can prepare for everything but you can’t always prepare for an hour delay and a circle changing every round. It’s the little things you know, I just couldn’t get to grips with the circle in warm up at all.
"I got no rhythm or timing and by the time the competition came it was dry and it was different. I just wasn’t good enough today. Not good enough to adapt quick enough."
11:59 BST - Britain's 4x400m mixed relay team have been speaking after setting a record-breaking time to qualify for tonight's final.
"We are obviously really happy to get the job done and get into the final with a national record," said Joe Brier. "We worked really well as a team, so we are very pleased to have run that time."
Laviai Nielsen added: "It was fast and loud, so I think that gave us an extra lift. We have all been itching to go so we are pleased with how we have performed as a team."
"We have come here to win so we will be giving everything to go for gold and come out on top," said Yemi Mary John.
11:45 BST - We're underway in the women's heptathlon with Ireland's Kate O'Connor comfortably clearing 1.65 and then 1.68 in the high jump. How will Johnson-Thompson fare?
11:05 BST - New record! GB and NI have set a British record in the mixed 4x400m relay with a time of 3:11.19.
The quartet finished behind the USA who clocked a world leading time of 3:10.41. Ireland qualified in fourth with 3:13.90 - a season's best.
10:51 BST - Katarina Johnson-Thompson finished sixth in a fast 100m hurdles heat, clocking 13.50. American Taliyah Brooks set a season's best 12.78 to get her bid for a maiden gold off to a flyer.
Next up for Johnson-Thompson will be the high jump at 11:45am.
10:50 BST - Spain's Alvaro Martin has won the first gold of the Championships with a scintilating time of 1:17:32 in the men's 20km race walk. The double European champion finished ahead of Sweden's Perseus Karlstrom and Caio Bonfim of Brazil, both of whom set new national records.
10:46 BST - GB and Northern Ireland's quartet for the mixed 4x400m relay heat has been confirmed as Joe Brier, Laviai Nielsen, Rio Mitcham and Yemi Mary John. Ireland's team will be Jack Raftery, Sophie Becker, Christopher O'Donnell and Sharlene Mawdsley.
They will take to the track at 11:05am.
10:27 BST - The opening track and field event of Budapest 2023 - qualifying for the men’s shot put - is about to get underway. The event was picked out as a highlight by World Athletics president Seb Coe and will feature British hopeful Scott Lincoln.
Lincoln is expected to face tough competition from two-time Olympic champion Ryan Crouser, who smashed the Olympic record in Tokyo 2020.
The 30-year-old will need to throw 21.40 to qualify.
09:50 BST - We're underway in the men's 20km race walk - the first medal event of the Games. The rain is easing off, and we should see the morning session in the stadium start in around 40 minutes.
09:18 BST - The rain is having a knock-on effect with the schedule as all events are currently delayed. We should still the full programme as the forecast looks promising from around 10.30am, but it will take some time to clean up the track.
08:28 BST - The weather is expected to hot and sunny over the coming week but this morning it’s thundery and lashing with rain, meaning the men's 20km race walk - initially scheduled for 7:50am - will start at 9:50am.
08:11 BST - Which GB and Northern Ireland athletes are competing today?
All eyes will be on world record-chasing Zharnel Hughes in the men’s 100m qualifiers later this evening, but before then there’s a host of action in the morning session.
Scott Lincoln is first up and will begin his bid in the shot put from 9.30am. Commonwealth Games gold medalist Katarina Johnson-Thompson (heptathlon) will take to the track in the third heat of the 100m hurdles at 09:49 with European indoor champion Jazmin Sawyers (long jump) at 11:25am.
GB and NI’s 4x400m mixed relay team will be in the first qualifying heat at 10:05am, and there’s a trio of athletes to look out for in the women’s 1,500m heats (from 12:15) - including gold medal contender Laura Muir, Melissa Courtney-Bryant and Katie Snowden.
08:00 BST - Welcome along to the opening day of the 2023 World Athletics Championships in Budapest.
Records are widely expected to tumble over the next eight days as the world’s greatest athletes vie for podium places in the last meeting before the Olympic Games next year.
Over 2,000 athletes from more than 200 countries will be taking part in Hungary's biggest-ever sporting event. It’s set to be a thrilling exhibition of sporting excellence, and we’ll bring you every moment right here.
Most of the action will take place inside the city’s purpose-built 35,000-seater National Athletics Centre on the banks of the Danube river, but the race walk and marathon will see athletes weave around the centre of the city itself.
Great Britain won seven medals in the pandemic delayed Games in 2022 - can they do better this time around?
Budapest is buzzing, the world is watching, so let’s get straight to it!
