This video captures the Westminster Hall debate held on the evening of 15 June 2026, triggered by the Brain Cancer Justice petition, which gathered roughly 109,000 signatures.

The debate, opened by Paul Davies MP on behalf of the Petitions Committee, brought together MPs from across all parties, with a Government minister responding. It reflects the petition's central argument that brain cancer is the biggest cancer killer of children and adults under 40 — with 87% of high-grade brain tumour patients dying within five years — yet receives only around 1% of national cancer research spending. Speakers raised the cases of constituents and families affected by the disease, pressing the Government to turn what is too often a terminal diagnosis into a treatable condition through faster research progress and wider treatment options.
