Karsten Warholm speaking to BBC Sport: "I love the track and the crowd here, it gives me that special feeling. I always try to race hard, that is why I don't race too much. I can't chase the dollars. This is my own priority. Of course I think a little about the world record, but a European record sounds good as well. But I want more."

Wow - that was phenomenal! Yes, we expect Karsten Warholm to blast off and hang in to the finish but this time it was more controlled and his technique was smooth.

He was confident he was getting his stride pattern right and the only one he had to check his stride was the last barrier, but he still managed to charge in.

I think he was expecting that performance the way he was driving off the last hurdle. A phenomenal warning to the rest of the 400m hurdles field.

47.13!

A new personal best for Karsten Warholm which moves him up to sixth in the all time list and makes him the fastest man this year.

And he did it solo. There was no-one else on the scene.

Karsten Warholm shocked the world on this track when he won the world title in 2017. His celebration became something of a meme as well. The Norwegian set a European record last time out in Oslo.

Two-time Diamond League champion and Commonwealth Games gold-winner Kyron McMaster from the British Virgin Islands is his most obvious opposition.

Kyle Langford has been talking to BBC One about his £1,000 fine after an incident where he appeared to grab a race official by the throat.

"I am pretty laid back and take things in my stride. I know I've really mucked up in the last couple of weeks, my actions were completely out of sorts and it's bothered me.

"I know I'm not a bad person but sometimes things get to you, but there's no excuses.

"Two weeks ago I dislocated my knee and tore ligaments and I thought my season was over but I have rehabbed hard and have to thank Charlie Grice because I've seen how hard he has worked and he was my motivation to work hard in the pool.

"Two weeks ago i couldn't walk!"

Beth Dobbin speaking to BBC Sport: "It always takes me a couple of races to get into the swing of things and I had not run sub 23 yet this season so I was a little worried. But you can't complain with that PB!

"I had a little stumble out of the blocks and I think that actually gave me a kick up the bum and got me going!"

Heptathlete Katerina Johnson-Thompson finished ninth in 23.19.

That was a great race from Elaine Thompson but she looked a little tight in the final few metres, but she kept her form well to hold off Marie-Josee Ta Lou.

Beth Dobbin got her third with a strong finish which was very impressive.

Victory for the multiple Olympic champion Elaine Thompson in 22.13.

But Britain's Beth Dobbin claims third and a personal best behind Marie-Josee Ta Lou. 22.50 for the Briton.

Elaine Thompson - the fastest women in the world this year over 100m and the 100m-200m double gold winner at Rio 2016 - is the class of the field.

She is unlikely to come under much pressure to be honest, but Switzerland's Mujinga Kambundji and Ivory Coast's Marie-Josee Ta Lou are a good bet to get closest.

Heptathlete Katerina Johnson-Thompson is mixing it with the single-event specialist in this one with fellow Britons Beth Dobbin and Bianca Williams also in the field.

The 29-year-old's main rival will be Portugal's Pedro Pablo Pichardo - the only other man to go beyond 18 metres.

Ferguson Cheruiyot Rotich scored the win in 1:43.14 in his absence with fellow Kenyan Wycliffe Kinyamal second.

There were personal bests for Jamie Webb in sixth (1:44.52) and Kyle Langford (1:44.97) in ninth.

This is a busy and busting field with 13 men scrapping over two laps.

The fastest two in the world this year - Botswana's Nijel Amos and Kenya's Ferguson Rotich - are present and correct.

Rotich's compatriots Wycliffe Kinyamal - a winner in Lausanne - and Emmanuel Korir - who won in London over this distance last year - will also be in the mix.

Britons Elliot Giles, Kyle Langford and Jamie Webb will be up against it to feature in the finish, but could be dragged round to a good time.

That was a very impressive run from Zharnel Hughes. He looked controlled, majestic, and pulled away from a world-class field with so much ease.

We know he's a quality 200m runner but here now in 100m he seems to be the complete sprinter.

He has such a smooth action but I wish he had kept going all to the line because you never know Linford Christie's British record of 9.87 seconds could have been under threat.

Correction, Antigua and Barbuda Cejhae Greene is third in 10.14.

CJ Ujah is the best placed Briton behind Zharnel Hughes in 10.19 and sixth. James Ellington finishes ninth in 10.93 seconds.

Zharnel Hughes wins in 9.96 at a trot. Massively impressive.

Andre De Grasse is second in 10.05 with Japan's Yoshihide Kiryu third in 10.16.
