Guy will be joined by three-time European junior champion Matthew Johnson and 2012 junior champion Molly Renshaw in a team with a wealth of experience and success on the European junior circuit.

"We have a very strong team, 11 of whom are medallists on the European Junior stage so we are looking to put in some strong performances in Dubai," said team leader Mark Perry.

"Some of the squad have competed before at the World Junior Championships and they will be looking to improve on their previous performances."

The World Junior Swimming Championships will take place at the Mohammed Bin Rashid Sports Complex in Dubai later this month

Head coach Graeme Antwhistle added: "It's a small, but focused team with lots of talent.

"The World Junior Championships gives the swimmers the opportunity for high quality racing at the end of the season, against the best in their age group.

"For some this will be their first double taper experience but I have no doubt that the whole team will be able to step up for the competition and race hard."

The full British junior World Championships squad is as follows: James Guy, Caleb Hughes, Matthew Johnson, Max Litchfield, Karl Morgan, Mark Szaranek, Emma Day, Georgina Evans, Jessica Fullalove, Amber Keegan, Charlotte McKenzie, Molly Renshaw, Sophie Taylor and Grace Vertigans.

The World Junior Swimming Championships are due to take place in Dubai from August 26 to August 31.
