Although the headline says England, it seems this will include Wales:
"The Telegraph understands that UK ministers are considering refusing to recognise gender recognition certificates (GRCs) which would be issued under the new SNP system, which will operate under a "self-identification" modell_ and remove any medical checks.
It is understood that UK officials are working through the implications of the policy for England and Waless_, as Scottish-born people living south of the border would be eligible to apply for a Scottish certificate."
On schools and prison, the article says:
"While it is understood a final decision has not been taken, UK officials are aware of potential problems such as Scottish-born male prisoners in English jails taking advantage of the Scottish system and then demanding to be moved to a women’s facility.
They also fear implications for schools if Scottish-born pupils in England change their legal sex, as 16- and 17-year-olds would also be able to apply, compared to 18 in the rest of the UK."
