Ellie Simmonds claimed her second gold of London 2012 when she won the SM6 200 metres individual medley and broke her own world record in the process for the second time in a day.
As with her heat swim this morning, the 17-year-old produced a blistering freestyle leg to go past Oksana Kruhl as if she was treading water to win in three minutes 5.39 seconds, dipping 0.75secs inside the mark she had set this morning.
The Swansea-based swimmer had been shocked by her earlier performance today and on seeing the scoreboard tonight, she had a beaming smile on her face.
It was her second title of the week after her success in the S6 400m freestyle, also in a world record time.
Not to be forgotten, team-mate Natalie Jones took bronze in 3mins 14.29secs but all eyes were on Simmonds.
A delighted Simmonds told Channel 4: "I'm so pleased that I won - a world record again, another PB and to go on the podium again. I'm just so chuffed.
"Two golds now and I'm going to enjoy it.
"That was a tough race. I was just trying to go as fast as I can and to do a PB.
"I'm just really happy.
"My front crawl is my main stroke, it's where my advantage is, where I catch people up. She was ahead of me, and I panicked a bit. I didn't know if I could catch her up.
"I just kicked for home and really went for it."
Jones, said: "I've worked so hard for this over the last three months. I'm just so delighted that I've got a medal."
Sascha Kindred was under the old world record but still finished second as he made up for his earlier disappointment with silver in the S6 200 metres individual medley.
The 34-year-old had not been dislodged from the top of the podium since first claiming gold in Sydney 12 years ago and this morning went some way to making up for his fourth in the 100m breaststroke as he qualified fastest for the medley final.
Kindred was fourth at halfway before his breaststroke leg pulled him up to second, narrowly behind Xu Qing.
It looked as though it would be a stroke-for-stroke duel but the Chinese pulled away to take 3.37 seconds off Kindred's world record in two minutes 38.62 seconds.
The Briton also dipped inside his old mark to claim silver in 2mins 41.50secs.
He told Channel 4: "That was what I wanted: a medal in this event. It's not the colour I wanted, but [it's] a new European record, a PB, so I've done my fastest time on the biggest stage so I can't ask for more than that.
"It took a world record to beat me.
"I'm going to stand on the podium and be glad of that silver medal."
