The 28-year-old clocked a time of 60.29sec to better the mark she set on her way to the gold medal at Rio 2016 by 0.24 seconds.

Hermitage now turns her attention to the women's 100m T37, the other event in which she is a Paralympic champion, on Saturday (July 22). 

"I am so relieved," she said.

"That feels like a really long straight out there and I was totally spent by the end.

"I wasn’t sure at all about the time so was very surprised to see it was a world record."

Ukraine’s Nataliia Kobzar claimed the silver medal in 62.83 and China’s Jiang Fenfen came away with bronze in 64.35.

Hermitage’s team-mate Hannah Cockroft had earlier delighted the home crowd by completing a gold medal hat-trick with victory in the women’s 400m T34.

The 24-year-old posted a Championship record time of 58.29 to add to the 100m and 800m titles she won earlier at the event.

It completes the same treble she achieved at both the 2015 World Championships in Doha and Rio 2016.

"I’m feeling really emotional - I even had a little cry," Cockroft, a winner of five Paralympic gold medals, said.

"I was confident until yesterday when I got full of cold.

"When I came to the start line, I felt like I had nothing to put into the race.

"All the way round I was thinking, 'I can hear the girls coming, I’m not going fast enough, I’m not going fast enough'.

"So to get that result, when I was feeling like this, is such a relief."

The United States’ Alexa Halko was Cockroft’s nearest challenger with an Americas record of 59.93.

Completing the top three was another home favourite Kare Adenegan, who clocked 1:02.94. 

Joining Cockroft in racking up a third gold medal of the Championships this evening was Tunisia’s Walid Ktila.

He triumphed in the men’s 800m T34 to add to his victories in the 100m and 400m.

Ktila won in a Championship record time of 1min 44.79sec and will now look to complete a repeat of his gold medal haul from the previous two World Championships with victory in the 200m final tomorrow. 

World record holder Mohamed Alhammadi of the United Arab of Emirates beat Ktila to 800m gold at Rio 2016 but had to settle for the silver medal on this occasion in 1:45.28.

Britain’s Isaac Towers won the bronze medal in 1:46.46. 

Also continuing his superb form this evening was Canada’s Brent Lakatos.

He made it three gold medals from four events so far with victory in the men’s 800m T53.

A time of 1:40.14 was enough to ensure he added to his wins in the 200m and 400m.

Thailand’s Pongsakorn Paeyo finished runner-up to Lakatos in the 200m and 400m and dropped to bronze in the 800m in 1:42.07.

France’s Pierre Fairbank upgraded to silver in 1:41.97 having finished third in the 200m and 400m.

China’s Shi Yiting was in world record-breaking form this evening, winning the women’s 100m T36 in 13.68 to add to the 200m crown she won on Tuesday (July 18).

Shi sliced 0.14 seconds off the previous best mark set by compatriot Wang Feng during Beijing 2008.

Argentina’s Yanina Andrea Martinez claimed silver in 14.41 with South Korea’s Jeon Min-Jae third in 15.06.

The men’s 400m T54 event saw Tunisia’s Yassine Gharbi come out on top with a Championship record of 45.57.

The Netherlands’ Kenny van Weeghel took the silver medal in 46.55 and Britain’s Richard Chiassaro was just 0.01 behind in third.

Switzerland’s Marcel Hug, winner of the 1500m T54 on Sunday (July 16), came fourth in 46.58.

In the men’s 100m T37, Brazil’s Mateus Evangelista Cardoso took gold ahead of Paralympic champion Charl Du Toit of South Africa in a reverse of the 200m final on Tuesday.

Both athletes managed season’s bests but Evangelista Cardoso’s time of 11.48 was 0.07 seconds faster than that of Du Toit.

Rounding out the podium was Ukraine’s Vladyslav Zahrebelnyi in a personal best 11.69.

Rio 2016 Paralympic silver medallist Mostafa Fathalla Mohamed ended up fourth, despite posting a season’s best 11.78.

China’s Liu Cuiqing won the women’s 400m T11 in a time of 58.51 with Mexico’s Diana Laura Coraza Castaneda second in 59.11 and Poland’s Joanna Mazur third in 61.94.

Bulgaria’s Ruzhdi Ruzhdi produced the stand-out performance in the field events by winning the men’s shot put F55 with a world record throw of 12.47m.

Poland’s Lech Stoltman came away with a silver medal with a season’s best 11.37m and Iran’s Hamed Amiri was the bronze medallist with 11.17m.

Germany’s Niko Kappel also broke a world record on his way to claiming victory in the men’s shot put F41 title.

A throw of 13.81m was three centrimetres further than the mark he set himself in front of a home crowd in Munich last month.

Britain’s Kyron Duke won the silver medal with 12.28m for silver and China’s Xia Zhiwei threw 11.86m to take bronze.

Paralympic and world champion Mi Na of China posted a Championship record of 35.08m to secure the women’s discus throw F38 title.
