Trans women in custody will be searched by male officers following Wednesday’s landmark Supreme Court ruling, the British Transport Police have said.

A British Transport Police spokesperson said: “Under previous policy, we had advised that someone with a Gender Recognition Certificate (GRC) may be searched in accordance with their acquired sex, however as an interim position while we digest yesterday’s judgement, we have advised our officers that any same sex searches in custody are to be undertaken in accordance with the biological birth sex of the detainee.

“We are in the process of reviewing the implications of the ruling and will consider any necessary updates to our policies and practices in line with the law and national guidance.”
