Thirty eight swimmers have been confirmed as part of Team GB for this summer's Olympic Games following the British trials in London.
The athletes were formally nominated to the British Olympic Association by British Swimming.
Olympic champion Rebecca Adlington and world champion Liam Tancock are among the 19 men and 19 women selected.
There are a number of places yet to be filled on the GB swimming team, with a second trials to come in June.
Daniel Fogg became only the third Briton to go inside the 15-minute mark when he won the 1500m in 14 minutes 55.30 seconds at the Aquatic Centre on Saturday night, with 2004 bronze medallist David Davies joining him in sealing an Olympic place.
Head coach Dennis Pursley identified the breakthrough of younger swimmers as the most positive aspect of the competition.
"What excites me most about this meet - for the first time since I've been here, some of the kids have stepped up," said the American.
"Young kids finally stepping up and in some cases knocking off the veterans and swimming stroke for stroke in some races which I think bodes well for the future."
Team GB swimmers won three medals in Beijing: Adlington took gold in the 400m freestyle and 800m freestyle, and Joanne Jackson won bronze in the 400m freestyle. British swimmers also won three medals in the open water 10km events.
Michael Scott, British Swimming's national performance director, said: "This GB swimming team is a real mix of tried and tested experienced former Olympians together with an exciting crop of talented youngsters who will sample their first Olympics in London.
For events in which two swimmers did not achieve Olympic qualification times, the second trials in June will be crucial.
If, in Sheffield, a competitor can record a time quicker than those of the top-two athletes from the British Championships, then they will be selected for Team GB at the London Games.
"This week has seen some impressive performances at the national championships but our job is far from done.
"Collectively we now have the time and opportunity to improve upon the performances this week to make sure we are as competitive as possible for when the rest of the world arrives in London in July."
Fran Halsall will compete in three events at the Olympics, having qualified for the 50m freestyle on the closing day of the trials on Saturday.
"To get on the team is great," she said. "I'm in such good form at the moment so if I can carry that through to the Olympic Games, hopefully I can swim a bit faster there."
Robbie Renwick, who has secured places in the 200m & 400m freestyle, added: "It's an incredible feeling. It's been a dream of mine for quite a few years so to qualify for the Olympics is amazing."
Saturday's announcement takes the number of confirmed Team GB athletes for the London Games to 59, with those coming from athletics, boxing, sailing and swimming.
