Wheels of fire.

GB's Sammi Kinghorn wins her second gold medal of the championships, her third overall, and still the 800m to come tonight.

She pulled away at the 40m mark and was never going to be caught.

Sammi Kinghorn has already won gold in London this week (in the 200m) and her story is a remarkable one.

Before the championships started, she spoke to BBC Scotland about the tragic accident when she was 14 which would change her life.

You can watch the video here.

That brings the Great British medal tally to 38, the same total won as in Christchurch, New Zealand in 2011.

Sammi Kinghorn, a gold medallist and world record breaker in the women's 200m T53, is the next Brit to go and could take Britain to their highest medal total in recent times.

I say recent times as they picked up 69 medals in 1998 in Birmingham, but there were many, many more events in that championships so that distorts the figures a bit.

This graphic shows the medals picked up at previous World Para-athletics Championships, the first total is gold, then silvers, then bronzes and then total medals won.

Time for some quotes from a delighted Jordan Howe, one of three Britain's silver medallists so far today.

"I knew it was going to be tough to race these boys. It was my time to shine and I did," said 21-year-old Welshman Howe, who competed in the men's 100m T35

"I've been working with some great people. All year I knew if I was with them at 60m I could change the gear and I did.

"I was calm, I wasn't nervous. I want to progress now. I've got a great team in Newport with Christian Malcolm."

Hi ho silver!

GB have served up the silvers on a platter this morning and this is another top-notch performance as Mickey Bushell.

He takes Britain's third silver medal of the morning - none of which were bankers - as Canada's Brent Lakatos claims a fourth gold of the championships.

"The start, the first 30 to 40 metres will be challenging for most of the men, Mickey Bushell's start is normally great, but his challenge comes in the last 20 metres."

These are the British competitors who have won gold so far in these championships. Will this list be extended later on today? Mickey Bushell is up next, and he has a Paralympic gold medal in his trophy cabinet.

It's worth noting that while Welshman Jordan Howe had a medal time in him, he has never competed in such intimidating circumstances.

With a handful of bronze medals at European Championships to his name, this was a breakout performance.

Howe is still jogging around the track soaking this all in.

And there's more to come from GB.

Hollie Arnold, a gold medallist in the women's javelin F46 earlier this week, is loving the British performances so far, including the efforts of Polly Maton, Steve Morris and Jordan Howe.

That was superb from Jordan Howe, he reacted well, was in about fifth, but then he found his running and he is absolutely going mad, celebrating with the crowd, he is so, so pleased. A silver medal, that is fantastic.

It's double silver for GB this morning as Jordan Howe slaps down a personal best of 12.52 seconds in the T35 100m.

It's gold for Ukraine's Ihor Tsvietov and bronze for Herman Barreto of Argentina.

Jordan Howe, a European bronze medallist, goes next in the men's 100m T35 - for competitors with cerebral palsy.

Let's hear from Britain's T47 long jump silver medallist Polly Maton, who has been talking to BBC Radio 5 live.

She says: "It's absolutely amazing. I found really good form coming into the holding camp and had a calf niggle before the 100m.

"It was about pulling myself together for the long jump. I've had a rubbish season with the long jump, especially with my calf and I wasn't expecting this."

One of the stories of Saturday was the performance of Great Britain's Aled Davies, who destroyed his own world record to take gold in the shot put F42 event.

The 26-year-old Welshman says sacrifice and hard work since the 2016 Rio Paralympic Games culminated in his win at the World Para-athletics Championships yesterday, as he threw a world record of 17.52m.

The 26-year-old from Bridgend also took gold in the F42 discus, the third time in succession Davies has taken both events at the competition.

A peculiar race this. Cristiano Pereira of Portugal charges off like a bull and the assumption is that 1500m champion Mikey Brannigan of the USA will reel him in, But he doesn't, and it's silver for the American.

It's fifth place again for Great Britain's Steve Morris and a personal best time of 15 minutes 14.04 seconds.

That's three times he has been close to a medal here - fourth in the 1500m and another fifth in the 800m.

They develop some pretty decent athletes at the Whitchurch High School in Cardiff.

In the same school year a few years ago was Wales footballer Gareth Bale (pictured), British and Irish Lions captain Sam Warburton and Steve Morris, who is in action right now in the final of the men's 5,000m T20.

Morris, 28, was diagnosed with dyspraxia at the age of two and has just missed out on medals so far, coming fourth in the 1500m and fifth in the 800m.

Polly Maton's silver medal has taken the British tally up to 36 for the championships, only two less than the 38 they won in Christchurch, New Zealand in 2011, but there is still time to beat that figure.

Yesterday was cold, wet and gloomy. But a treble of gold medals for Britain lit things up somewhat.

Today, we have the final day blues at London Stadium as we enter the penultimate session of what has been a tremendous 10 days.

The good news is the sun is out and, by my untrained eye, this looks like the biggest crowd we've had for a morning session.

Inspired by London 2012, 17-year-old Polly Maton has now won a silver medal at the same stadium where she was a spectator five years ago.

What a story and congratulations to her.
