The 37-year-old, who set new 100m, 200m and 800m T53 world records in nearby Arbon last week, crossed the line in 2min 51.84sec to take more than two seconds off the mark set by Switzerland’s Marcel Hug in 2010.

"It’s great - I had no idea coming in to this weekend that I would be anywhere near this kind of shape," Lakatos, a seven-time world champion, said.

"It’s just completely unexpected and I couldn’t be happier about it."

Great Britain’s T54 racer Richard Chiassaro finished second in 2:52.11, a time which also went below the previous world record and earned him a European record.

Fellow Briton Hannah Cockroft secured her fifth world record since the Swiss series began in Arbon, this time smashing the women’s 1,500m T34 mark with a time of 3:50.22.

It is more than 11 seconds quicker than the previous time set by Britain’s Melissa Nicolls three years ago.

The men’s 1,500m T34 world record also fell today as Tunisia’s Walid Ktila took nearly two seconds off his previous best.

The 31-year-old, who topped the individual medals table at the 2015 World Para Athletics Championships in Qatar’s capital Doha, finished well clear of the field as he crossed the line in 3:09.93.

Lakatos, Cockroft and Ktila also won their 100m races in the morning session with respective times of 14.34, 17.40 and 14.97.

Kuwait’s Ahmad Almutairi, meanwhile, equalled the world record in the 100m T33 - a mark he set back in 2015 - as he crossed the line in 16.46.

After losing out in the 200m T51 yesterday, former Paralympic champion Toni Piispanen of Finland turned the tables on his great rival Peter Genyn of Belgium over 100m.

Piispanen clocked a time of 20.68, beating Genyn by a margin of 0.18 seconds.

Finnish success continued as Leo-Pekka Tahti took the win in the men’s 100m T54 in 13.74 - 0.11 seconds shy of his world record.

Another Finn in winning form was world silver medallist Amanda Kotaja, who won the women’s 100m T54 in 16.67.

China’s Lihong Zou was the runner-up in 16.74, while home favourite Manuela Schär finished third in 16.91.

Schär later made amends with a strong performance in the women’s 1,500m T54, crossing the line in 3:24.72 with Zou second in 3:26.33.

The Netherlands’ Marlou van Rhijn, a double Rio 2016 Paralympic gold medallist, secured her second win in Nottwil after coming out on top in the 100m T43/44 in 13.16.

Britain’s Richard Whitehead, the 200m T42 world and Paralympic champion, came through to win the men’s 100m T35-47 on points after clocking 12.17.

South Africa’s Charl du Toit, the 100m T37 Paralympic champion, took second place with a time of 11.61.

Out in the field, Canada’s Becky Richter managed 14.52m in the women’s club throw.

French F57 thrower Marcelin Walico posted a European record of 38.43m in the men’s javelin F31-57.

The World Para Athletics Grand Prix is due to conclude on Monday (June 5).
