A statement said: “It is clear that tennis and padel are gender-affected sports – the average man has an advantage when playing against the average woman.

“The current broad consensus, including the conclusion of the review carried out by the Sports Councils Equality Group, is that this advantage is likely to be retained to a significant degree in trans women, making competition potentially unfair.

“We are changing our policy to restrict trans women and non-binary individuals assigned male at birth from playing in the women’s category in Specified, inter-venue, competitions.

“We want to encourage local venues to ensure that they are as inclusive as possible for trans and non-binary individuals, providing opportunities to compete in a friendly environment. In line with this, our own Local Tennis Leagues product (largely played in parks) will remain fully inclusive.”

The new policy is the result of an 18-month process involving consultation with affected groups and other sports, and the LTA pledged to review the policy going forward.

One of those who had been campaigning for it is coach Judy Murray.

She said: “I’m all for inclusivity in sport, but we’ve always had categories for a reason: to make it fair and to keep it safe…When children reach puberty, the boys begin to pull away from the girls hugely because they obviously become bigger, stronger and faster.”

She noted that boys are typically “more competitive” and “more robust than girls in general.”
