A Catholic media commentator has been instructed by police to present herself for questioning after being reported for using the wrong pronoun to describe a transgender girl on Twitter.

Caroline Farrow, 44, has been told police in Surrey want to conduct a “taped interview under caution” after receiving reports she had made ‘transphobic’ comments online. She is being investigated under the Malicious Communications Act, and although the interview would be voluntary, she claims she could face arrest if she does not attend.

Mrs Farrow, who does not believe people can change sex, had taken part in a heated debate with transgender rights campaigner Susie Green on Good Morning Britain. Mrs Green’s transgender daughter Jackie Green was born Jack before becoming one of the youngest people in the world to undergo sex-change surgery after turning 16. Six months after the on-air debate, Mrs Farrow and Mrs Green were involved in a spat on Twitter, during which Mrs Farrow allegedly used the wrong pronoun to describe Mrs Green’s daughter.

Mrs Farrow wrote on twitter: “’We are in the middle of a national conversation about what it means to be male and what it means to be female. Nonetheless, following my appearance on National Television the CPS [Crown Prosecution Service ] have decided I need to be interviewed under caution for misgendering Susie Green’s child.”
