Miley strikes gold in Istanbul
Hannah Miley won GB's first gold medal at the World Short-Course Championships when she held off Ye Shiwen in the 400m individual medley.
Ye was at the centre of the biggest controversy in the pool at the 2012 Olympics, her freestyle leg en route to victory other-worldly.
In London the Chinese teenager was just three hundredths of a second slower over the final 100m than Ryan Lochte, winner of the men's race.
Indeed, her last length was faster than four competitors in the men's final including Lochte and Thiago Pereira, the gold and silver medallists.
Miley, fifth in London, had qualified fastest into the final but predicted it would be a different race come tonight, claiming the Chinese teenager was "playing" in this morning's heats.
Fourth after the butterfly and backstroke legs, Miley then produced a superb breaststroke to turn first going into the freestyle, 2.04secs ahead of Ye.
However, as expected, Ye came back and on her final 25m of 28.14 seconds - the only sub 29-second last length in the field - she reeled Miley in.
The Scot, though, was breathing to her right where she could see her rival, who she held off by 0.19secs to win in a new championship record of four minutes 23.14 seconds, the fastest ever in a textile suit and bettering her own mark from the European titles last month.
The 23-year-old "was hanging on for dear life" and admitted the achievement had significance for both her and her father and coach Patrick, vindicating their approach after the Olympics.
Miley said: "A lot of top athletes aren't here, so for me I see it as an opportunity and any opportunity I see I try and take it.
"So for me I was aiming for it to be a confidence booster for both myself and my dad and what we are doing this season.
"Not only were we trying to chase placings but also to do a really good time which I was really happy with.
"But the main thing is long-course (50m) swimming so I am really happy with what I've done, but for me I am not going to be happy with it until I can prove I can do it long-course as well."
Lochte is contesting nine events at the Sinan Erdem Dome and tonight he claimed two gold medals - in the 200m freestyle and as part of the victorious United States' 4x100m freestyle relay.
The 11-time Olympic medallist appeared to be heading for an emphatic victory in the individual event, but world record holder Paul Biedermann closed in on the penultimate length and then came off the final turn ready to attack.
However, Lochte held off his rival to touch in 1:41.92 before returning to qualify fourth for tomorrow's 100m butterfly final, which is loaded with quality.
The Florida Gator swam the second leg as the United States won the sprint relay in 3:06.40, with the women victorious in the 4x200m relay in 7:39.25.
In the night's other final, Hungary's Katinka Hosszu beat Olympic champion Jiao Liuyang to take the 200m butterfly title in 2:02.20, a championship record.
