Britain’s Kathleen Dawson claimed a sensational European 100m backstroke title despite having to swim the final twice during controversial evening of swimming in Budapest.
Dawson won the initial final in 58.18 seconds before it was discovered a faulty speaker had prevented Sweden’s Louise Hansson from hearing the starting buzzer.
The result was annulled after appeal.
And two hours later Dawson return to claim victory in 58.49.
“I’m so proud of myself,” Dawson said.
“My coach got me back into the right mindset and sure enough I was able to go through and produce the swim that I did.
“I knew though that as soon as I had the chance to swim again that I was going to be number one and be stood on top of the podium.”
Dutch swimmer Kira Toussaint who took silver in the first final finished fourth, swapping places with Margherita Panziera of Italy, who was second in the re-run final.
Russian Maria Kameneva finished third in both races, with Cassie Wild repeating her fifth-place finish.
“I’d actually swum down and was thinking about getting the coach back to the hotel when I heard,” Wild told BBC Sport.
“It was probably more of a mental game than a psychical one, but as it was my first major final I’ll take the extra experience ahead of the Olympics.”
Molly Renshaw was another British swimmer to claim a first individual international gold medal on the fifth night of swimming in Budapest, with victory in the 200m breaststroke final.
“It was a really tough race and hurt, but I’m over the moon,” she told BBC Sport after recording a time of two minutes 21.34 seconds.
“I’ve won bronze and silver medals before but I’ve always dreamt of winning major events and this gold has come at the right time so it’s a great stepping stone towards the Olympics.”
There was also a sixth relay medal for the British team in Budapest with the women’s 4x200m freestyle line-up claiming gold with a dominant display.
The quartet of Lucy Hope, Tamryn van Selm, Holly Hibbot and Freya Anderson finished in a time of 7:53.15 which was outside the automatic Olympic consideration time set by the British Swimming selectors, but they are hopeful the event will be chosen for the Games.
Duncan Scott won 200m freestyle silver in 1:45.19, with team-mate Tom Dean (1:45.19) taking bronze in a race won by Martin Malyutin (1:44.79) of Russia.
Adam Peaty was the quickest qualifier for the 50m breaststroke final after recording 26.38 in the semi-finals.
World Championship bronze medallist Luke Greenbank has qualified quickest for Saturday’s 200m backstroke final after breaking the British record for the second time in a day.
His latest effort of 1:54.43, was 0.24 secs quicker than the time he recorded in the heats.
