She later finished third in the SB7 100m breaststroke and SM7 200m individual medley at Tokyo 2020.

"This sport has taught me so much about the person I am," Thomas Kane said.

"It was never about the results but more about the love I had for the sport and the opportunity it gave me which I never thought I’d achieve."

Thomas Kane's international career began at just 13 when she was selected to participate at the 2015 World Championships in Glasgow.

Despite her young age, Thomas Kane won gold in the SB6 100m breaststroke.
