A university has banned phrases such as “right-hand man” and “gentleman’s agreement” under its code of practice on inclusive language.

Cardiff Metropolitan University’s guidance dictates that “gender-neutral” terms should be used where possible, adding that students should not allow their “cultural background” to affect their choice of words.

It advises that the terms “forefathers”, “mankind” and “sportsmanship” should be avoided, as part of efforts to “embrace cultural diversity” through language.

The university has been accused of undermining free speech and “insulting” students and academics by attempting to dictate their choice of words.
