Military Helicopters: Blood Cancers

Debate between Ayoub Khan and Al Carns

Tuesday 8th July 2025 Westminster Hall

[Al Carns]

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.

[Ayoub Khan]

As a lawyer, I know there are always complexities around causal links, statistics and experts. There will always be a differing opinion. Does the Minister agree that anyone who has been part of the military should have available to them a legal team, funded by legal aid, to progress a claim—as opposed to a lawyer in a no win, no fee arrangement, which can bite into a substantial chunk of any compensation?

[Al Carns]

I will need to come back to the hon. Member on the specific legalities around that issue; I am not a lawyer. The war pension scheme and armed forces compensation scheme for individuals provide a route for compensation, in any way, shape or form. If there is a cause, as far as I am concerned there will absolutely be a redress or compensation scheme to support that, but I will write to the hon. Member on that issue. I want to be really clear on that last point. Although the IMEG’s findings provide some reassurance, I want to be absolutely clear that I have been exploring options for a broader, holistic review of the cancers. We talk about the simplicity of finding the data, but I want to give hon. Members the scale.

There are 2.1 million veterans in the UK. We do not track cancers post-service for those veterans. In some cases, we do not even know where those veterans are. We do not know where the pockets sit. We can have a rough view, and make a guess, but we do not have the statistical data. The Valour programme, which we launched a while back, should help build up a clear understanding of our veteran demographic and the issues that veterans face, and help address them in the most programmatic way.

At the moment, the data does not exist. We will continue to work with independent experts in both the UK and, importantly, the US, to closely monitor and understand any emerging evidence around aircraft exhaust fumes and cancers. Let me reiterate: we will continue to monitor the data. We will monitor this issue closely and act decisively if concerns are identified.
