Wheelchair racer Sammi Kinghorn contributed to Britain’s success at the Paris Paralympics by taking a stunning gold medal in the 100m in the T53 category at the Stade de France. Scottish athlete Kinghorn, who took silver in the 800m and 1500m in recent days, stormed to the finish line ahead of Swiss star Catherine Debrunner to set a Paralympics record of 15.64 seconds. The 28-year-old became the first non-Chinese athlete to win the title since Tanni Grey-Thompson 20 years ago in Athens.

Tears of joy streamed from her eyes as she greeted her family in the stands before dedicating the win to her brother on his birthday. “I just can’t believe I did this,” she said. “It really blows my mind. This is definitely for my brother.”

Zoe Newson had experienced the joy of bronze medals in London and Rio, then the pain of fourth place in Tokyo, but on Wednesday in Paris the 32-year-old went one step further on the podium and won silver in dramatic circumstances at the Porte de la Chapelle Arena.

On the first day of the powerlifting competition, she attempted to lift the final 109 kg needed for second place, but was initially fouled. She and her team appealed, and after a tense break, she was awarded the silver medal.

“I didn’t realise,” Newson told the BBC about the decision. “It didn’t come on the screen but we heard the crowd start cheering. Then we saw it on the screen and we were absolutely ecstatic. My son and my fiancé are in the crowd so I got quite emotional.”

In the pool, Poppy Maskill won her fourth medal of a highly successful Games in the Women’s 200m Individual Medley SM14, adding a silver and two gold medals to the silver and two gold medals won by the 19-year-old from Cheshire on her Paralympic debut.

Maskill could still finish fifth in the 100m backstroke on Friday, but admitted the demands of the schedule are starting to take their toll. “It’s hard work,” she told Channel 4 after being narrowly beaten for gold by Valeriia Shabalina. “I’m just going to go back (to the athletes’ village), take a nap… and that’s all I’m doing.”

Maskill and her British teammate Olivia Newman-Baronius were in the lead after the first butterfly stroke, while Maskill pulled clear in the backstroke. “I wanted to see what I could do and what would happen,” she said. Shabalina touched the wall just ahead after the breaststroke and then kept the British swimmer at bay, who touched the wall just 1.53 seconds behind.

Rhys Darbey took silver in the men’s 200m individual medley SM14 behind Canada’s Nicholas Bennett. The Welsh swimmer, making his Paralympics debut, adds the silver medal to the gold he won on Sunday as part of the mixed 4x100m freestyle S14 team.

“I’m very happy about it,” he told Channel 4. “This is my first individual race at the Games and I came second. I won a medal in two out of two races, which makes me really happy.”

Alice Tai also won silver in the women’s 400m freestyle S8.

Sophie Wells won a bronze medal in the Class V individual dressage in Versailles, her ninth Paralympic medal in her fourth Games, after gold and silver medals in London, Rio and Tokyo.

Tim Jeffery won bronze in the R9 Mixed 50m Rifle Prone SH2 at the Châteauroux Shooting Centre. “The final was one of the hardest things I’ve done in a long time,” said the 28-year-old. “Hopefully this medal is the first of many.”

At the Stade de France, Karim Chan narrowly missed out on the bronze medal in the Men’s T38 Long Jump. His performance of 6.39m placed him just 1cm behind third-placed José Lemos. The Colombian completed an unlikely double medal haul after winning gold in the Men’s T38 Javelin last week.

The British women’s wheelchair basketball team were knocked out in the quarter-finals but gave the USA a scare on the way there. The British team led 50-49 with less than four minutes to go before the bronze medalists from Tokyo prevailed to win 59.52.

Andy Lapthorne and Greg Slade had to settle for silver in the wheelchair tennis quad doubles after losing 6-1, 6-1 to the dominant Dutch pair of Sam Schröder and Niels Vink. There was better news for Alfie Hewett, who marched into the men’s singles semi-finals with a 6-1, 6-4 win over Ruben Spaargaren, but Gordon Reid lost his quarter-final 6-0, 7-6 (5) to Argentina’s Gustavo Fernández.
