Single-sex girls’ schools in England will have to admit biologically-male pupils under Scotland’s proposed new gender recognition laws, says a new report. Girls’ schools would be guilty of discrimination under sex equality laws if they refused entry to biologically male teenagers who had been granted female gender recognition certificates from Scotland, according to the study by the think tank Policy Exchange published on Thursday. Scotland’s proposed new law allows people to change their legal gender without a medical diagnosis of gender dysphoria in as little as three months.
