How the Debate Unfolded
MPs spoke in turn to share their views and ask questions. Here's what each person said:
Lead Contributor
The number of children and young people presenting to the UK NHS with gender distress has increased year on year since 2009, with a significant rise in 2014. In 2016, there were 1,766 referrals to GIDS, two-thirds of whom were female. These children often suffer from neurodiversity, mental health issues and trauma. Studies have shown that puberty blockers do not provide psychological benefits and may even worsen symptoms in some cases.
Andrew Johnson

Dorset West
Emphasised the need to look at existing data on patients treated at GIDS and questioned why new trials were necessary. Raised concerns about NHS trusts not fully participating in research, urging the Government to ensure compliance with data-sharing requirements.
Caroline Johnson

Sleaford and North Hykeham
Declared interest as an NHS consultant paediatrician, expressing concern over a fiftyfold increase in diagnoses of gender dysphoria. She questioned the planned trial's focus on long-term outcomes and raised concerns about the risks associated with puberty blockers, including impacts on bone density and neurodevelopmental effects.
Helen Morgan
LD
North Shropshire
Supports the establishment of multiple regional centres to reduce waiting times but highlights that only two centres are open currently in London and North West, leaving many young people on long waiting lists. Confirmed meeting with Dr Cass and supporting the clinical trial recommended. Helen asked for evidence of the consultation to be published for families' confidence in the ban decision. She emphasised the importance of research following international best practices and respecting medical decisions made by patients and clinicians.
Jim Shannon

Commended the decision to ban access to puberty blockers for young children, expressing concerns about long-term safety and efficacy based on lack of comprehensive studies. Highlighted alignment with UK policy in Northern Ireland.

Tim Roca

About Westminster Hall Debates
Westminster Hall debates are a chance for MPs to raise important issues affecting their constituents and get a response from a government minister. Unlike Prime Minister's Questions, these debates are more in-depth and collaborative. The MP who secured the debate speaks first, other MPs can contribute, and a minister responds with the government's position.
