Contribution

This debate is on a subject that, it goes without saying, is emotive and complex. We must therefore as always endeavour to have this conversation with compassion and empathy. The Liberal Democrats’ position is clear and simple, as reflected in our amendment to the motion: any medical treatment and the approval of any clinical trial, including the one we are discussing, must be led by expert medical advice. It should not be led by personal belief, no matter how sincerely and passionately that belief is held. Politics has a place, but not in questions of medical trials and clinical consensus—those are better left to experts. The Cass review, originally commissioned by the Conservatives, was clear that there was a need to gather more evidence. The safety of young people is paramount, and the experts involved in this space know that better than anybody; they work with these children day in, day out and understand the risks of both action and inaction. That is why we supported the previous decision to pause the trial after the MHRA raised concerns, and why we now support the decision to start it again. We will listen to the experts and the clinicians, but to build trust in expert advice we need transparency and clarity, and throughout the process, we have pushed for exactly that. We want the expert opinions on the public record, as that allows us as politicians, as well as the wider public, to approach this issue with clarity and facts, not ideology or misunderstanding. That is why we called for the Government to publish how the MHRA arrived at its decision when concerns were first raised, and yesterday we called for the Secretary of State to confirm that the MHRA had confirmed that its concerns had been substantially addressed. Transparency is needed so that people can be confident that clinical advice is being followed.
