High jumper Jonathan Broom-Edwards said winning his first Paralympic gold was “an emotional rollercoaster” as Great Britain won six medals in Friday’s athletics sessions in Tokyo.

There was also gold for Paralympic debutant Owen Miller in the T20 1500m.

“To get it right, at the right time, I’m relieved, elated, excited, crying my eyes out,” Broom-Edwards said.

“It’s been an emotional rollercoaster. I’ve been striving for it. To keep my cool and get it right when it counted, I’m really proud of myself.

“I always believed in myself and I wanted to come here and jump a new personal best. The weather didn’t play ball but to do a season’s best is amazing.”

Miller, 29, won gold with a brilliant last lap, coming from fifth place with 400m to go and overtaking Russian Alexander Rabotnitskii on the last bend before sprinting home to clock three minutes 54.57 seconds.

“It went exactly the way I wanted. I timed it right and knew I could do it,” he said.

“I gave it my all. I went for it and knew nobody was going to catch me. I could never really imagine I’d be a Paralympic gold medallist when I took up the sport, but I am today.”

Richard Whitehead, who clocked 23.99 seconds, was beaten by 0.40 by South African Ntando Mahlangu – at 19, 26 years his junior – in the T61 200m final, while there was also silver for the universal relay squad of Libby Clegg, in her final race before retirement, Jonnie Peacock, Ali Smith and Nathan Maguire.

The quartet finished third but were promoted after runners-up China were disqualified and Clegg said that ending her career with a medal was a dream come true.

“I’m so privileged and proud to be a part of this team and share this moment with these guys,” she said.

“Right now, this is my proudest moment – being part of this team.

“I’m going to take some time out but this is my last running competition, unless I dabble in a sports day when my son is at primary school.”

Peacock paid tribute to Clegg, who has now won five Paralympic medals.

“Libby’s put herself through so much pain over the last couple of weeks to get into all the races,” he added.

“So to come away and to run two blistering legs in the heats and final, and get us a silver medal, I’m so proud of her and proud to be a part of this team.”

Defending champion Hollie Arnold could only take bronze in the F46 javelin while there was also bronze for Hannah Taunton in the women’s T20 1500m.

Arnold, who appeared in the ITV show I’m A Celebrity…Get Me Out Of Here last year, led going into the final round with a best of 39.73m but was overhauled by New Zealand’s world record holder Hollie Robinson (40.99m) and Dutch debutant Noelle Roorda (40.06m).
