Puberty Blockers

Christine Jardine Excerpts

Tuesday 23rd June 2026 Commons Chamber

[Christine Jardine (Edinburgh West) (LD)]

It is a pleasure to follow the hon. Member for South Derbyshire (Samantha Niblett), who made a very effective and powerful speech. All of us here today are concerned about the safety and wellbeing of children, and we want to ensure that young people facing a crisis of identity get the support that they need and that is appropriate for them. In many cases, that will be talking therapies. We need to give children and their families time to figure out exactly what the issue is and whether they will develop out of it in time, but that is not always the case.

My concern, and I believe the concern of many here today, is for those children who do not, as the hon. Member for Sleaford and North Hykeham (Dr Johnson) put it, grow out of it as if it were some problem—children who have a genuine fear of what puberty will bring, and of what adulthood in a body that they do not recognise as theirs will mean. Those children currently feel that they have no option. If we take away the possibility of puberty blockers, where will they go? Where will they turn? Too many young people are committing suicide, and we have to acknowledge that that is the very real danger of putting up a very different type of block—a block to understanding and to helping them develop.

[Rebecca Paul]

I thank the hon. Lady for giving an eloquent speech. It is really important that we are very responsible in the way we talk about suicide, and I would like to point out that Professor Louis Appleby did a study on exactly this issue following the ban of puberty blockers. His conclusion was that we were not seeing an increase in suicides as a consequence. He also made the point that it is important not to suggest that denying young people puberty blockers causes them to commit suicide. That is a negligent thing to do, and it is important that we put that on the record.

[Christine Jardine]

I thank the hon. Lady, but I point out that that is not what I said. I said that we were leaving children without an option. I also point out that if we are going to be responsible, we should not accuse people of being homophobic because they are trying to support the transgender community. Many of those people who support the transgender community are lesbians or gay. I know this because I am the honorary president of the LGBTQ+ community within the Liberal Democrats, and there is a great feeling of community between the two. I would caution people not to call anyone who wants to support the trans community homophobic. 

These children need our support. In providing that, we should listen to clinicians and experts, such as Dr Hilary Cass, who has said, as so many Members have pointed out, that this trial will help protect children and will mean that they are less likely to be harmed. I think we should take that as our guiding principle.

My hon. Friend the Member for Mid Sussex (Alison Bennett) clearly laid out my party’s policy. I am proud of the fact that, as a women and equalities spokesperson, I was responsible for the formation of most of our policy on the transgender community. I have to say that I spoke to a great many of them, and they would be appalled if they felt for one moment that we were not going to support them, not going to support this trial or not going to stand up for them at a time when they are under increasing pressure and we are seeing the demonisation of that community.

The young children facing a crisis of identity—wondering who they are, and wondering what support they will get—are looking to us to give them that support, and that is why I will oppose the Conservatives’ motion.

--- Later in debate ---

[Sir John Hayes]

Baroness Cass certainly wanted to gather more evidence. The evidence we have shows the damage that puberty blockers can do. We know that the substantial science suggests that they affect bone maturation, cerebral capacity and, of course, fertility. It is certain that there is no compelling evidence that puberty blockers have a beneficial effect. That is why she sought more evidence, as she concluded that there was no compelling evidence that they have a beneficial effect.

[Christine Jardine]

As another member of the liberal working class, I wonder whether the right hon. Member has the experience that many of us in this place have of talking to constituents, friends and family who have children who have struggled with their gender identity and have benefited from puberty blockers. While he says that there is no evidence, many of us have direct experience of seeing the benefits in action.

[Sir John Hayes]

That experience clearly contradicts the Cass review’s findings, but it is for the hon. Lady to have that debate, no doubt, with Dr Cass.

What is certain is that we have no indication from the Government about what success in the trial will look like. When challenged on that subject, answer came there none. How will we gauge whether the trial is a success or a failure? Are these children really guinea pigs to be used to provide the evidence that the hon. Lady says is already freely available in her anecdotal experience of communicating with her constituents and others?

We know that there is certainly evidence from other countries. Have the Government looked to draw on that, rather than engaging in this dangerous trial? We know that there is evidence too from the 2,000 or more children who went through Tavistock. Some have suggested that we should look at the data already available rather than putting any more children at risk. Yet despite the Secretary of State’s agonised decision—I do not intend that to be sarcastic or pejorative; I appreciate that the Secretary of State was completely straightforward about how difficult it was to make the decision—the trial goes ahead. I accept that there are additional safeguards—this is not Tavistock; it is something different—but none the less it brings immense risk alongside the determination to try to gain facts. Instead, let us look at Finland and Denmark and at other countries that have already gathered evidence. Let us look at what we know of those who have already been through this process.

G. K. Chesterton said:

“children are innocent and love justice”.

I fear that this trial will steal their innocence and deny them justice. I hope that even at this late stage the Government, recognising that, will abandon this awful trial and save innocent children from that fate.
