Question to the Ministry of Justice:

To ask the Secretary of State for Justice, pursuant to the Answer of 21 May 2025 to Question 51904 on Prisoners: Gender Recognition, how many of the prisoners with a Gender Recognition Certificate are biological (a) males and (b) females.

The latest published data (a snapshot from 31 March 2024) shows that there were 10 prisoners known to have a Gender Recognition Certificate (GRC). The full data report can be viewed here: HMPPS Offender Equalities Report 2023/24 - GOV.UK.

Because the number of prisoners who hold a GRC is so low, we are unable to provide further information beyond the total figure (including other personal characteristics and location) as this risks disclosing which individuals hold a GRC, which is an offence under Section 22 of the Gender Recognition Act 2004.
