At the end of this article. I don't see why MtF would get to go in the girls at all. They can use the male changing rooms first, as per their sex. Good news on the actual competitive sports though.
"The education secretary also disclosed new details of new guidance which aims to support transgender children in schools. He said that trans children should be “accommodated” and that trans girls could be allowed to use girls’ changing rooms before others do so.
He also said trans children should be allowed to wear the uniform of their choice but that trans girls should not be allowed to join girls’ sports teams competing in single-sex matches or fixtures. “If you are biologically stronger you should compete with people who are biologically equal,” he said."
