Puberty Blockers

Harriett Baldwin Excerpts

Tuesday 23rd June 2026 Commons Chamber

[James Murray]

I thank the right hon. Gentleman for the tone he took in asking an important question, which I am pleased to be able to respond to. The bar for getting on to this trial is set extremely high, with strict eligibility criteria: parental consent, alongside the young person themselves consenting or assenting; a diagnosis of gender incongruence for at least two years; and consent from both the NHS care team and a national multidisciplinary team, including a wide range of disciplines, to understand all aspects of a young person’s health, context and situation. The level of approvals and scrutiny that young people will have to go through to participate in the trial will, therefore, set the bar extremely high.

[James Murray]

I will give way one more time, and then I will make some progress.

[Dame Harriett Baldwin]

I am grateful to the Secretary of State for giving way. He mentioned parental consent—what would happen in a situation where the child was in the care of the state? Would they be included or excluded from this trial?

[James Murray]

If a child is looked after under a care order, the local authority has parental responsibility, so it would need to be part of the consent process as the corporate parent.

I turn to the points raised by the right hon. Member for Salisbury (John Glen) about young people becoming involved in the trial and the checks that are in place to enable that to happen. As I set out earlier, as the trial involves children, it comes with a responsibility to interrogate and understand its design. As Health Secretary, I have sought the most detailed assurances possible from my clinical advisers as to how children taking part in the trial will be protected.

There are a number of important safeguards. As I have said, children can participate only with the consent of a parent or guardian, and the child themselves must consent or assent. They can participate only if they have had a diagnosis of gender incongruence for at least two years, have received psychosocial support through the NHS and are of stable physical and mental health. They can participate only if they are not subject to any safeguarding concerns and if they and their parents demonstrate sufficient understanding of the nature of the treatment, including its possible advantages and disadvantages. They can participate only if the treatment has been deemed clinically appropriate by both the NHS care team and the national multidisciplinary team and if they are already accessing NHS gender services. On eligibility, the bar is extremely high.

The number of young people who would expect to qualify for the trial will be low and the safeguards to ensure their safety and wellbeing will be rigorous. I have sought and had an assurance that, once they are involved in the trial, participants may be withdrawn at any point. We are not proceeding with the previous, now decommissioned, model of care overseen by the Conservatives when they were in government. We are proceeding cautiously, with rigorous safeguards in pursuit of the evidence, as Dr Cass recommended.

Last Thursday, the independent MHRA approved an updated protocol that significantly strengthened the objective criteria for withdrawing children from the trial, which is a change that I welcome. Signs of greater risk to participants will now trigger increased monitoring, clinical review or their automatic withdrawal from the trial. All participants will be monitored before, at the start of, every three months during, and after the trial. Before and during the trial, information will be collected about mental health, quality of life, self-harm and suicidality, body image, cognition, puberty stage, physical health and side effects.

I have been determined to ensure that the oversight of this trial is as rigorous and robust as it possibly can be, so I have requested monthly updates on its progress. That will include my being notified of any emerging risks.

This trial is rightly one of the most scrutinised UK clinical trials of recent times. We should expect nothing less when we are talking about the health and wellbeing of some of the most vulnerable children in our country. Yet, as Dr Cass has made clear, we have to build the evidence base to show whether the treatments are safe and whether they produce the positive outcomes that young people and clinicians want from them.

The Opposition’s motion would prevent us from following expert clinical advice, when proceeding with the trial is the most appropriate way forward. I say that not because I am suggesting that we should feel instinctively comfortable in doing so but because I have arrived at that conclusion after considering the clinical evidence and receiving robust assurances on the safeguards that are in place.
