The 20-year-old, winner of the 100m title in a world record time last Saturday (July 15) before suffering the disappointment of disqualification from the 400m on Wednesday (July 19), clocked a time of 21.21sec.

It took 0.28 seconds off the time which he set in front of a home crowd in São Paulo in April 2015.

"I was always focused and motivated for the 200m and what happened in the last two days only motivated me even more for my best effort in the 200m," Ferreira dos Santos said.

"I knew I was in good form, but I didn't know I could go that fast.

"Thanks to London for helping to fuel me a lot."

Ferreira dos Santos’ compatriot Yohansson Nascimento, the 200m T46 Paralympc gold medallist at London 2012, came second in 21.96.

Rounding out the podium was Poland’s Michal Derus in 22.08.

Also breaking their own world record this evening was Britain’s Sophie Hahn.

She produced a blistering time of 12.44 in the women’s 100m T38 to slice 0.16 seconds off that which she set to win the same event at the 2015 World Championships in Doha.

It comes exactly a week after Hahn broke the 200m world record on her way to victory.

"I am so happy to win this title," the 20-year-old said.

"I’ve been off for a week so waiting to get out here again has been difficult.

"To do the double of 100m and 200m is just phenomenal.

"I think this is the biggest run I’ve ever performed - it felt amazing and the crowd here really moved me along."

Fellow Briton Kadeena Cox was a distant second in 13.07 and Germany’s Lindy Ave came third in a personal best 13.16.

Another world record came Britain’s way in the men’s shot put F42 as Paralympic gold medallist and two-time defending world champion Aled Davies obliterated his own previous best mark of 16.13 metres, set in American city Tempe in May 2016, with a throw of 17.52m.

Iran’s Sajad Mohammadian managed 14.44m for the silver medal and Germany’s Frank Tinnemeier came third with 13.87m.

There was more British success in the women’s 100m T37 which saw Georgina Hermitage triumph in a Championship record time of 13.36.

Ukraine’s Nataliia Kobzar finished runner-up in a personal best 13.60 and the United States’ Jaleen Roberts third in 13.69.

In today's opening session, Australia’s Jayden Sawyer clinched his first-ever world title with a men’s javelin throw F38 world record.

The 23-year-old, whose best-placed finish in major competition up to now had been third at the 2013 World Championships inLyon, went into the lead with his third-round effort of 51.05m.

But it was his final-round throw of 52.96m that really impressed, adding 58 centimetres on to the previous world record mark set by Iran’s Mohammad Naeiminia in Tehran in May. 

Paralympic champion Reinhardt Hamman of South Africa threw a season’s best 50.48m for the silver medal and bronze went to Ukraine’s former discus and shot put Paralympic champion Oleksandr Doroshenko with 49.63m.

American sprinter Jarryd Wallace claimed his first world title since 2013 with victory in the men’s 200m T44.

The 27-year-old, who already had a bronze medal from the 100m, clocked a time of 22.37.

Greece’s Michail Seitis and South Africa’s Arnu Fourie were given same time of 22.53, but it was the former who took the silver medal.

Ireland’s Michael McKillop made it double gold at these World Championships after adding the men’s 1500m T37 title to the 800m T38 crown he won on Sunday (July 16).

The four-time Paralympic gold medallist posted a time of 4min 36.38sec to finish ahead of Canada’s Liam Stanley, the runner-up in 4:37.96, and Algeria’s Madjid Djemai, the bronze medallist in 4:41.93. 

The order of the podium was the same as that from Rio 2016. 

The men’s 800m T13 final was an extremely close contest with Fouad Baka beating twin brother Abdellatif to the gold medal in a reverse of the 1500m event on Wednesday.

Fouad achieved a Championship record time of 1:51.60, beating his sibling by 0.09 seconds.

Morocco’s Mohamed Amguoun clinched the bronze medal in a personal best 1:51.84, edging Algeria’s Mohamed Fouad Hamoumou.

Cuba’s Luis Felipe Gutiérrez broke the Championship record three times on his way to the gold medal in the men’s long jump T13.

Victory secured his second global title, having also won at Lyon 2013.

The 29-year-old, winner of the Paralympic title back in the same stadium in 2012, leapt 7.40m in the fourth round having already managed 7.36m and 7.38m.

Rio 2016 bronze medallist Louis Radius of France took the silver medal in 4:12.25 and Paralympic champion Abbes Saidi of Tunisia third in 4:12.37.
