The Green Party has vowed in its manifesto to institute controversial guidelines from the World Professional Association for Transgender Health, or WPATH, which include availability of puberty blockers for teenagers. This is despite strong criticism from the Cass Review in the UK which highlighted the lack of an evidence base for such drugs.

In their manifesto, the Greens pledge to “Implement a community-based, person-centred model of trans healthcare, ensuring universal access to evidence-based care. Our policy will be guided by the World Professional Association for Transgender Health.”
