Campaigners demanded an urgent review of the puberty blockers ban last night over a trans lobby group’s offer to help children exploit loopholes. Hours after they were permanently banned by the Government last week, Anne Trans Health started offering youngsters ‘legal, compassionate and supportive routes’ to access the body-altering hormones, which halt development into adulthood. The organisation is led by Susie Green, 56, who previously ran controversial trans charity Mermaids, which promoted sex reassignment surgery and sent chest binders to young girls without their parents’ knowledge. The ban prevents NHS or private doctors from prescribing puberty blockers for gender dysphoria. It also bans the sale and supply of them from doctors in Europe.
