President Donald Trump has signed an executive order that aims to restore “biological truth to the federal government” of the United States.

It accompanies a pledge by the new administration to “defend women’s rights and protect freedom of conscience by using clear and accurate language and policies that recognise women are biologically female, and men are biologically male”.

Trump, who during his 2024 presidential campaign focused much of his criticism on transgender issues and the handling of them by the Biden administration, signed the order on the very same day as his inauguration as the 47th US president on 20 January.
