Pablo Mateo of France wins the first heat, in 10.18 seconds. Italy's Matteo Melluzzo is 0.03 further back, and just 0.01 ahead of Danish runner Simon Hansen.

Every sliver of a second counts.

The first eight men are on track for the first of three 100m heats

24 competitors at this stage, 14 go through to the semi-finals.

Lawrence Okoye has had a fairly decent season. Okoye threw a season's best in Doha with 64.95m.

He has won a bronze European Championship medal and a Commonwealth Games silver medal in his career.

Daniel Stahl of Sweden is the reigning Olympic champion. He threw 63.02 metres with his first effort.

Kristjan Ceh of Slovenia is the early pace setter, with 66.59m.

GB's Morgan Lake with her second jump at 1.85m - she makes it.

A settler for the British athlete.

European record holder Mykolas Alekna leads the way, the athletes all get six throws each.

The Lithuanian reigning champion starts with a no-throw. Oof.

Here's Lawrence Okoye of GB... 62.56m. A warm-up distance, really.

Still early days in women's high jump qualifying.

GB's Morgan Lake has just failed at her first jump, 1.85m.

Three successive faults and you are eliminated, so she'll need to get it right fairly quickly.

Our second medal final of the night is about to get under way.

The men's discus has a stacked field, including European record holder Mykolas Alekna of Lithuania.

Lawrence Okoye represents Great Britain in this final too.

Here's the first gold medallist of the 2024 European Athletics Championships - Antonella Palmisano.

And doesn't she look pleased after leading home an Italian one-two in Rome.

Looking back at the footage of the end of the race walk, it does look a bit suspect... but we have no word of any official appeal yet.

I can remember in the 2002 European championships an Irish sprinter had to duck under a boom camera!

Paul Brizzel was the Irish sprinter and unlike Poland's Klaudia Wojtunik he did not qualify for the final in his rerun.

Well this is a very strange turn of events.

This morning, Klaudia Wojtunik of Poland was disqualified from the women's 100m hurdles for a false start. She appealed and was successful - which means she is now re-running her race. On her own.

It's not unprecidented, but is incredibly rare. Three lanes of hurdles have been set up, and Wojtunik will run through the middle lane.

Here she goes...

She runs it in 13.22 seconds, which is good enough to send her into the semi-finals as the 11th and final qualifier!

Elena Carraro of Italy, who was in that 11th spot, is knocked out.

Remarkable.

Good news for the athletes - the heat and humidity in Rome is petering out.

It's now a very temperate 25 degrees celsius in the Italian capital.

The British interest in the men's 100m, starting tonight, is not as strong as it might have been.

Zharnel Hughes - who was limping after a race in Jamaica last weekend - and Jeremiah Azu, who ran a a personal best 9.97 seconds in May, are both absent due to injuries.

"We had a few injuries with Zharnel Hughes and Jeremiah Azu – they are two key members of the team, and they would have strengthened our team massively," GB & NI sprint Richard Kilty told BBC North East.

"With those two in the team, we would have been very difficult to beat out here, but the goal is to go out there and win."

CJ Ujah is the man representing Great Britain and Northern Ireland in the 100m tonight, having been the centre of significant controversy in recent years.

Ujah was part of the 4x100m relay team who won silver at Tokyo 2020, but failed a drugs test - meaning all three of his team-mates were also stripped of their medals.

One of those three was Richard Kilty, who has spoken to BBC North East about Ujah's actions.

"I don’t have an Olympics medal no more; it has gone and it is no longer there," Kilty, who at 34 is hoping for one final crack at the Olympics in Paris, said.

"My son is seven and he understands what happened.

"I had to hand the medal back. He started to realise how serious it was, the motivation is to go and win another Olympic medal and finally close the curtain on what would be a great career.

"I would have every medal in the book."

Here is confirmation of the qualification results in the men's shot put competition.

Great Britain's Scott Lincoln is safely through to Saturday's final.

No rest for the wicked. Qualifying has just commenced in the women's high jump.

Morgan Lake is the British representative.

A strong start to the championships for Great Britain and Northern Ireland.

Their first contender in the stadium, Scott Lincoln, is through to the men's shot put final with a throw of 20.31 metres.

He ranks sixth of the 12 qualifiers. A good showing in the final, and a medal is not out of the question.

No luck of the Irish for Eric Favors.

Silas Ristl of Germany has just supplanted him in 12th place, the final qualifying place for the final. Irishman Favors will not compete for a medal.

And as I type, Zane Weir of Italy goes past both of them into the top 12. A huge, emotional reaction from Weir, clearly pumped to perform for a home crowd as he celebrates that throw with his coach and competitors.

It has been three years since unfancied Lamont Marcell Jacobs shocked the world with Olympic gold in the men's 100m final in Tokyo.

Now, Italian Jacobs will hope to take another positive step as he prepares to defend his title after running a season's best 10.03 in late May.

He will begin his bid for glory on home soil in the 100m heats from 20:10 BST.
