Two-time Olympic swimming champion Tatjana Smith has switched from representing South Africa to the Netherlands with immediate effect. The 29-year-old, who holds both South African and Dutch passports, is due to make her Dutch-team debut at the short-course World Championships in Beijing from 1 to 6 December.

Smith had announced her retirement after the Paris Olympics, where she won gold in the 100-metre breaststroke and silver in the 200 metres. She previously won Olympic gold in the 200-metre breaststroke and silver in the 100 metres at the Tokyo Games.
