Hermitage claimed the women’s 400 metres T37 crown with a time of 1min 02.48sec, 0.22 seconds faster than her mark set at last month’s IPC Athletics Grand Prix in Berlin.

The 26-year-old, who returned to athletics after the birth of her daughter in 2012, finished ahead of France’s Mandy Francois-Elie and China’s Li Yingli in second and third respectively. 

"I thought I had over done it in the first 200m, I think I nearly got a personal best over 200m," said Hermitage, whose performance helped highlight an event that was the highlight of National Paralympic Day in Britain. 

"I came off the gas a bit round the bend, I saw the clock ticking down and thought I had over cooked it but I'm happy.

"I felt really tired in that last 100m and the crowd just carried me through.

"I know it sounds clichéd but it definitely does help."

Hahn posted a time of 13.00 in the women's 100m T38 race break the 13.04 she clocked in Loughborough last year.

Russia’s Paralympic champion Margarita Goncharova took the runners-up spot, while another Briton, Olivia Breen, completed the top three.

There were also home successes in the men’s 200m T42 for Richard Whitehead and in the women’s 400m T34 and 200m T12 for Hannah Cockroft and Libby Clegg.

Back on the same track where he set the world record at the Anniversary Games two years ago, Browne entered the race in superb form, having set a world lead of 10.72 earlier in the week.

His compatriot Jarryd Wallace, the 200m world champion, got off to a terrific start out of the blocks, but with 50m to go, Browne pushed hard to the front, crossing the line in 10.96 with Peacock in second and Wallace in third.
