I thank the hon. Member for his intervention. Various programmes reach out to those serving, and those who are ex-serving, to highlight the risks of serving in defence. The lack of evidence linking the two together withholds us from being very specific but, generally, we push really hard for everyone in defence with any indication of an issue caused by service to get it seen to, and make sure that a claim goes forward. The testing programme that we are putting in place is a proactive measure, reflecting our commitment to the highest standards of health and safety. It involves rigorous analysis of emissions from all operational helicopters, conducted in accordance with approved methodologies, ensuring that we have a clear understanding of any potential risks. We will not hesitate—and I will review this regularly—to take swift action if required, once that data is compiled. This is about more than compliance: it is about meeting existing safety standards, and about trust. It is about demonstrating to our personnel that their safety is our unwavering priority. As part of that commitment, the independent medical expert group, as mentioned by my hon. Friend the Member for Truro and Falmouth, was asked to review not just the UK but worldwide medical literature on this issue. It concluded that there was no evidence of a medical, causal link between helicopter exhaust fumes and rare blood cancers. But, as I have mentioned to my hon. Friend, although that provides an element of reassurance, we remain vigilant and committed to monitoring any emerging evidence. That is critical. With the Department, I have been exploring options for a broader holistic review of cancer diagnosis in service personnel, which should give us an iron-clad view of certain groups across defence. Throughout that process, we will keep personnel, their families and this House informed, but that is quite a comprehensive study.
