I thank the hon. Lady for her question, and I am sorry to hear of the experience of her three constituents. There certainly is hope within the long-term workforce plan. We are reliant on researchers to submit high-quality research proposals, and that requires clinicians specialising in this area.

I thank my hon. Friend for his question, and I am sorry to hear of his own personal experience. He is absolutely right that in relation to children, we are very keen to find a way forward. The Government are committed to finding high-quality brain cancer research, and we expect to spend more as new research progresses. £40 million of funding announced will remain available. We worked closely with Lord O'Shaughnessy on his review, accepted his recommendations, and put in £121 million to support it.

I thank the hon. Member for that question and join him in paying tribute to the hon. Member for Mitcham and Morden (Siobhain McDonagh), especially after the tragic loss of her sister, for all the work that she has done in campaigning on this issue. I have spent significant time on the issue and I have met her, campaigners, charities and other hon. Members from across the House. Funding for research is available and, having spoken with the Secretary of State, I know that he is as keen as I am to work with colleagues from across the House.

We are working closely with research partners, and although I am pleased to say that more research is being funded, we want to see more research in brain cancer treatments. We continue to encourage more researchers to become involved in what remains a challenging scientific area, with a relatively small research community.
