Swimmers Maia Dunleavy, Kelly Bone, Sophie Whelan and Leah Thomas-Daye made a splash at the London Youth Games when they won silver and bronze medals.
The games are Europe’s largest youth sports festival with pupils competing in 30 different sports.
Maia won silver in the Senior Girls 50m Freestyle and a bronze in the Senior Girls Freestyle Relay Team along with team mates Kelly Bone, Sophie Whelan and Leah Thomas-Daye.
It was the first time in the game’s 40 year history that Merton Girls Swimming Team has won two medals in the same year.
Catherine Lewis, Merton Swimming Team Manager, said: ‘The senior swimming team did the borough proud with the strongest performances since I began managing the team eight years ago.
“I’m immensely proud of all the swimmers. Maia, who has swum in the Merton team for five years, excelled again, winning her second individual medal for Merton after winning a silver in 2015.
The overall results for the borough’s swimmers also saw a massive boost with the Girls Swimming Team finishing 12th overall and the boys finishing 17th out of 29 boroughs.
