Pathways Study: Puberty Suppression

John Hayes Excerpts

Monday 22nd June 2026 Commons Chamber

[James Murray]

My hon. Friend asks about the data linkage study, and I apologise to my hon. Friend the Member for North Northumberland (David Smith), who a few seconds ago also asked about that—I did not respond then but can now address both questions together.

It is important to understand that the information in the linkage study is much more limited than the detailed information that the research team will be able to collect about the relative benefits and risks of puberty blockers. NHS England is, however, committed to delivering the data linkage study. NHS England, since assuming responsibility for that study, has taken time to ensure that the data is shared by relevant organisations. Let me be absolutely clear, for the avoidance of all doubt, that the Government’s clear expectation is that all relevant organisations will provide the data required to complete the study.

[Sir John Hayes (South Holland and The Deepings) (Con)]

I first raised the horrors of the Tavistock clinic in this House in 2019, having been provoked to do so by staff who said that they were often under pressure to refer for life-altering treatment children and young people who had experienced mental health difficulties, abuse and family trauma. Indeed, the Secretary of State will know that the Cass review found that childhood trauma, neglect and abuse featured heavily in the cohort of patients seeking gender changes. As many as two thirds of those referred had suffered neglect or abuse, with high levels of parental mental illness, substance abuse and exposure to domestic violence. So will the Secretary of State, even at this late juncture, abandon this trial? I have no reason to believe that he is anything other than a good man who wants to do the right thing. He has made it clear that he knows that this matter often sorts itself out through puberty and adulthood. I implore him to do so, for I fear that because he is a good man, he will regret this cruel experiment on harmless children.

[James Murray]

I thank the right hon. Gentleman for his comments, and although he and I come to a different conclusion on this, I do not doubt for a second the sincerity of his motivation in wanting to protect children and young people. I actually agree with him, as I said in my earlier comments, that most young children who are questioning their gender will resolve it on their own—let them be to resolve it. But there is a small subset of children who will need extra support, and within that there is a question about whether for a very small subset of them there might be a benefit to having treatment, and that is what this trial seeks to conclude.

I would add that the right hon. Gentleman refers to what happened in the Tavistock clinic and the stories that led to Dr Hilary Cass being commissioned. I think the right hon. Gentleman and I agree on how unacceptable that situation was, and I put on record my thanks to Sir Sajid Javid for commissioning the work by Dr Cass, because it has been such an important piece of work not only to expose what was happening before, but to provide a way forward.
