Diana Thomas (writer)

In 2019, Thomas began writing a column in the Daily Telegraph - A New Woman - about transitioning to become a woman, Diana Thomas. Julie Bindel, the feminist activist and writer, has criticised the column, pointing out that Thomas was previously a men's rights activist. Bindel described Thomas's 1992 book Not Guilty: The Case in Defence of Men, as "a rant about how feminists have the brass neck to blame men for the terrible things they do to women, rather than themselves." Bindel concludes of Thomas's views on women: "While feminists fight for the right for women to break free of oppressive sex stereotypes, the likes of Thomas claim them for [herself]." The column ended on 19 December 2020, with Thomas bidding an emotional farewell to her readers as she reflected on her harrowing transgender journey.

She spent 25 years as a journalist, working for publications such as The Daily Mail and The Mail on Sunday. She was mocked in Private Eye for her frequent contribution to these newspapers, being satirised as "Daily Thomas of the David Mail". In 1989, she became the youngest ever editor of Punch magazine, a role she kept for three years. in 1995, her comic novel Girl was published. In this, a man enters hospital for a minor surgery, but accidentally receives the sex reassignment surgery that was intended for another patient. Between 2007 and 2012, she wrote a well-received series of thrillers about a former Royal Marine, turned assassin, Samuel Carver.
