World junior champions Aaliyah Powell and Islay Watson have been named in Great Britain's squad for the 2018 Youth Olympics in Buenos Aires.
Powell will look to follow fellow taekwondo fighter Jade Jones who won gold at the inaugural Youth Olympics in 2010 before repeating the feat at the senior Games at London 2012.
Forty-two GB athletes will compete in the 2018 edition from 6-18 October.
"It's going to be an amazing experience," said windsurfer Watson.
"Because I won the Youth World Championships this year, I think I will have a bit of a target on my back, but the Youth Olympics is the icing on the cake and I couldn't have asked for a better way to round off the year."
The third edition of the summer Youth Olympics - following Singapore 2010 and Nanjing 2014 - will feature athletes ranging from 14-18 years old.
Team GB competitors will contest 17 of the 32 sports at the event, which will be the first Olympic competition in history to host the same number of male and female athletes from the 206 nations involved.
In addition to Jones, diver Tom Daley, swimmer Duncan Scott and gymnast Sam Oldham have all competed at Youth Olympics before attaining senior Olympic medal successes at subsequent Games.
"These events have helped shape the careers of Team GB Olympic stars and I'm sure it will act as a great springboard for this group of young stars," said Great Britain's chef de mission Mahdi Choudhury.
Among the other British athletes named in the squad are world junior champions Caroline Dubois (boxing), Michael Dalton and Theo Darlow (both rowing) as well as gymnast Amelie Morgan, who claimed a British record haul of five European junior medals last month in Glasgow.
European junior team silver medal-winning equestrian rider Jack Whitaker, the son of five-time Olympian Michael Whitaker, will also compete as will twin brothers Javier and Joaquin Bello in the beach volleyball competition.
European junior champion Charlotte Hope and team-mate Lauren Salisbury will become the first British karate athletes to compete in an Olympics before the sport's senior debut at Tokyo 2020.
