A colonel has claimed he was forced to quit the Army after he was criticised for stating that “men cannot be women”.

Dr Kelvin Wright, 54, had been a Reservist commanding officer with 14 years’ unblemished service, including two tours in Afghanistan, before his “honour was attacked” with a transphobia complaint and an investigation he described as “hellish”.

In May, he shared a post on his private Facebook account from Fair Play for Women, a campaign group that works with governing bodies to preserve women’s sport for those born female, which consisted of a quote from Helen Joyce, a feminist campaigner backed by the author JK Rowling.

The quote, shared without any additional comment, said: “If women cannot stand in a public place and say ‘men cannot be women’, then we do not have women’s rights at all.”
