Great Britain have added four medals to their haul from the pool at the Paralympic Games in Rio de Janeiro tonight.

Paralympic debutant Ellie Robinson, 15, collected gold in style in the final of the women's 50m butterfly S6 event, posting a time of 35.58s to set a new Paralympic record.

"I still can't believe it. I keep looking around to check. Oh my god it is so weird," she told reporters afterwards. "I put everything I have done in training into that race.

"I didn't think it was possible and I don't think it is possible now: I can't believe it! I feel like I am going to wake up and it is a dream."

Stephanie Slater claimed silver in the women's 100m butterfly S8 with a time of 1:10.32 to earn a Paralympic medal at her debut Games.

The 25-year-old had been an accomplished able-bodied swimmer - and tipped as a future Olympian - until she was diagnosed with nerve damage in 2011.

Susie Rodgers broke her personal best on the way to collecting her fourth Paralympic bronze medal with a time of 33.26s in the 50m freestyle S7.

"I have got to be happy with a lifetime best and a medal, plus I didn't get a medal in that event in London 2012," she said after the race.

"To be honest with you I was so pleased with how it went this morning; it was so tactical, I got myself in the lane that I wanted to be in and [Denise Grahl] pushed me all the way. Fair play to her for breaking the European record."

Meanwhile, 16-year-old Lewis White also picked up a bronze, smashing his own PB with a time of 4:21.38 in the 400m freestyle S9.

"It was unreal, I was not expecting that. It has blown my mind. I am not overly sure what has happened, I am a bit dazed. Give it four years and it may sink in!" he told reporters afterwards.

"Beating my personal best was more expected than the medal because I have put the hard work in so there is no reason why as long as I get my race plan right I can't go out there and perform. But what I got out there from doing that is just absolutely unreal."

ParalympicsGB's swimming team have now picked up three golds, three silvers and five bronzes in Rio.
