Question to the Department for Digital, Culture, Media & Sport:

To ask His Majesty's Government what assessment they have made of the accuracy and limitations of the sex-determining region Y test for determining the sex of British athletes; and whether they plan to commission further genetic and physiological data about the biological sex of British athletes.

We have always been clear that when it comes to women's sport, biology matters. We will continue to support sports to develop policies that protect fairness and safety, particularly when it is not possible to balance those factors with inclusion.

It is for each sport's National Governing Body to set their own policies for who can participate in domestic competitions, and it is for International Federations to determine the rules for their sports at the international level of competition.

This Government remains committed to working with UK Sport, the British Olympic Association, and the British Paralympic Association to ensure that UK athletes can compete under clear, fair, and legally robust international regulations.

Since a universal, one-time genetic test for all athletes in the female category across all Olympic and Paralympic sports is not yet set out or mandated, no estimate of the total cost has been made by the Government.
