UK Athletics has banned transgender women from competing in the female categories of their United Kingdom competitions and events.
The ban comes a week after World Athletics announced their own outlawing of male-to-female transgender competitors who have been through male puberty competing in women's elite events.
The move received support from former Olympians such as swimmer Sharron Davies and decathlon great Daley Thompson, though it also came under fire from some LGBTQ+ campaign groups.
Both bans will come into force from March 31.
"UK Athletics notes the revised World Athletics Eligibility Regulations for Transgender Athletes released on 23 March 2023 and coming into effect on 31 March 2023," a statement read.
"It is fair for athletes who have gone through male puberty to be excluded from the female category in Athletics.
"UK Athletics acknowledges and appreciates the efforts made by World Athletics to protect the female category in Athletics.
"From midnight on 31 March 2023, UK Athletics applies the World Athletics Transgender Regulations to all athletics competitions and events in the United Kingdom where the licence for the competition or event is granted by UK Athletics."
