A talented youngster trained out of Cockermouth in the north of England, Luke burst onto the scene by breaking the 200m backstroke junior world record at the inaugural 2015 European Games in Baku. Since then, he has gone on to win medals at European Championships, a gold in the memorable 4x100m Medley relay final at the 2019 World Championships, and a bronze at the same competition in the 200m backstroke which qualified him for Tokyo 2020.
