It's a second gold for Brent Lakatos!

He's pushed all the way by his Thai rival Pongsakorn Paeyo but the Canadian gets over the line first in 47.56 seconds - a Championship record.

Paeyo gets silver and Pierre Fairbank of France takes bronze.

Jason Smyth on BBC Radio 5 live, after winning his second gold in the T13 200m: "Incredible. Today you actually get to enjoy it. In the 100m on Sunday I knew I was back out again and had to rein it in. I'm delighted to be back in London. I wish we could have Worlds in London every time.

"I've worked it out over a four-year cycle it's 5,000 hours of training to run a 10-second race. But these moments are what make the hard work worth it."

Racing in the men's 400m T53 final is Brent Lakatos of Canada, who has dominated wheelchair racing for years.

At the age of six, Lakatos was involved in a freak ice-skating accident, and a blood clot formed on his spine that left his legs paralysed.

At first he turned to wheelchair basketball as his sport but soon he got the bug for the track and has now raced for his country at three Paralympic Games.

He won bronze in this event in Rio but also took gold in the 100m, having picked up three silvers in London.

Lakatos is married to British world champion Stefanie Reid, who picked up gold in the T44 long jump in London on Saturday.

They must have an incredible trophy cabinet at home...

A proper hearbreaking moment in the men's 400m T11 Final - featuring visually impaired runners.

Daniel Silva - the world record holder from Brazil - slowed down just a few metres before the line when in the silver medal position.

It looks like Timothee Adolphe of France is going to take gold...but then he stumbles and seems to be pulled over the line by his guide.

This will go down as an unofficial race, we think, for now. The officials will be looking at it.

It wouldn't be a London-based multi-day event if there weren't hundreds of volunteers lining the streets, paths and gantries in and around the stadium.

For the London 2017 events of Para-athletics and IAAF World Championships they are called Runners - and there are hoards of them.

From left to right, Alice, Chris and David have been welcoming and high-fiving thousands of spectators.

Alice said she wanted to get involved because she's a runner and wanted to feel part of an athletics event, while Chris said the spirit of volunteering encouraged her.

Ever wondered what a guide says to a blind 100m sprinter during the race?

Jerome Avery, the guide of American world champion David Brown, re-enacts the whole race and it sounds amazing.

Superstar racer Tatyana McFadden has breezed through into the final of the women's 800m T54.

The American finished first in the heats in 1:52.46 - a season's best

McFadden has already picked up three golds in London in the last week - in the 200m, 400m and 1500m - and is also the Paralympic champion x 4.

Luke Sinnott spoke to BBC Radio 5 live about his personal best in his final jump: "I really had to go into a deep, dark place to get what I needed for that last jump. I knew if I didn't put something on the board in that last jump then I'd be very disappointed."

Sinnott on competing at his first major event: "I can't believe I'm here. Those days you wake up and feel fate dealt you a bad hand, it just goes to show that if you take what's handed to you and you turn it around then you can become part of amazing stuff like this.

"There's a sensitive tipping point where you either end up here or you end up feeling sorry for yourself. Strapping a pair of blades was one of the best things I ever did."

Luke Sinnott's story is worth knowing.

The 36-year-old lost both legs in 2011, when an improvised explosive device detonated while he was on duty in Afghanistan.

He was invited to be part of the closing ceremony at the London 2012 games (you may remember him climbing a flagpole) and has now become a fully-fledged GB para-athlete.

He intended to compete at Rio 2016 in sailing but decided to switch to long jump. And on his world championship debut here in London today, he came agonisingly to making the podium.

Sinnott's first three jumps were chalked off for being over the mark. On his final attempt, he landed a PB of 6.15m and was just 10cms from taking the bronze.

Jason Smyth's wife and little girl were going bonkers during that race. The Irish flag gives them away.

He's done it! Ireland's Jason Smyth takes the world sprint double for the third time in his career.

Sabrina Fortune, bronze medallist in Rio, needs the throw of her life to sneak into the medals on her last attempt.

Argh. It's a foul and Sabrina slumps back into her chair - she'll finish sixth. She's looking down at her hands in disappointment but manages to applaud the Ecaudorian Poleth Sanchez who takes silver.

Rio champion Ewa Durska of Poland takes gold again.

It's happened for a long time - at pretty much every Olympics in fact. I think it's much easier for someone who's visually impaired to switch over. But with prosthetics it's so much more complicated.

Each athletics event is given a code, made up of one letter and two numbers, which is called a classification. It tells you more about the type of disability the athletes in that event have.

• The first letter will either be T or F: T is for track (running and jumping events) and F is for field (throwing events).
• The first number, from 1 to 5, tells you the impairment type: 1. Visual impairment 2. Intellectual impairment 3. Co-ordination impairment 4. Limb deficiencies and short stature 5. Impaired muscle power or range of movement.
• The second number ranges from 1 to 8 and designates the level of impairment, with 1 being the most impaired.

He's been referred to as Northern Ireland's answer to Usain Bolt.

And now Jason Smyth is aiming to add yet another gold medal to his already impressive haul.

The visually-impaired athlete was a double Paralympic champion at this stadium in 2012 and has a career best of 10.22 seconds in able-bodied competition, and a world record of 10.46 for Paralympic competition.

Smyth, 30, has been unbeaten at Paralympic level since beginning his international career at the 2005 European Championships.

He was fastest in qualifying for this event yesterday, as well. Ominous.

It's tight at the top.

Great Britain, the USA and China all have 11 golds each.

But it's China who are in first place as it stands, as they have more silver medals under their belt.

Coming into the evening session, GB have 11 golds, two silvers and seven bronze to bring their total to 20.

It's been fantastic. Not just on the field but the crowds have been noisy, which has made a big difference. I've set GB quite a high target of 37 medals. It would really help if every athlete that went out there now won a gold

This is Roger. Apparently his job is to sniff out suspicious items at London Stadium - but I think he's here just to look adorable.
