Two British transgender athletes are set to take part in this year’s Olympics, it has been reported. According to The Mail on Sunday, the pair, born male, have already represented Britain at a European championship sporting event, but their inclusion on the team for Rio is expected to cause controversy amid arguments over their biological advantage over competitors born as females. The inclusion of the two athletes arises from changes to International Olympic Committee guidelines which allow athletes to compete as their ‘preferred gender’ without having to undergo reassignment surgery.
