Military Helicopters: Blood Cancers

Tanmanjeet Singh Dhesi Excerpts

Tuesday 8th July 2025 Westminster Hall

[Jayne Kirkham (Truro and Falmouth) (Lab/Co-op)]

I beg to move,

That this House has considered military helicopters and blood cancers.

It is a pleasure to serve under your chairmanship, Sir Jeremy. I am here because of someone who joined the Royal Navy Fleet Air Arm at the age of 19 because he had always wanted to fly. He always had the vitality to attack life and live it fully. He flew everything from Hawks to helicopters, and was a talented and committed pilot. By the time I met him, he was teaching new recruits to fly at RAF Cranwell, and was Navy snowboarding champion. In 2005, he went to Cornwall and was stationed at Culdrose, where he flew search and rescue on the old Sea Kings. I represent Truro and Falmouth. Cornwall is rich in forces personnel and veterans. Five and a half per cent of people in Truro and Falmouth have served, which is a much higher percentage than the national average of 3.8%. In Truro and Falmouth, 4,160 houses—more than 10%—have at least one veteran living in them.

He was living in Dorset when he suffered strange symptoms of blood clots in his lungs and legs in the spring of 2022. It took some time and persistence, but he was diagnosed with multiple myeloma, a rare blood cancer that affects only 5,000 people a year in the UK and is most common in men over the age of 85. He was lucky to have some pioneering treatment in Dorset and later at the Royal Marsden hospital, and he was able to trial drugs that were not yet available in the UK. Treatment is developing for blood cancers all the time, and it is important that people in the UK have access to new treatments. The cancer, however, returned, and he died a year after diagnosis, not long after his 54th birthday. His was not an isolated case. Last Tuesday, in the Welsh Senedd, Julie Morgan led a debate very like this one about RAF winchman Zach Stubbings. Zach died from multiple myeloma at the age of 46, after working many hours on Sea Kings.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

I congratulate my hon. Friend on her excellent, sterling efforts to advocate on behalf of serving personnel and veterans, seeking answers on the important matter of military helicopters and blood cancers. Does she agree that although the current in-house testing of in-service helicopters is welcome, we must ensure full transparency on the matter so that there is work done for those who have previously worked on those helicopters? The health and wellbeing of our serving personnel must always be front and centre.

[Jayne Kirkham]

I agree absolutely. The health of our serving personnel is and always must be paramount. I will move on to previous cases shortly.

I know of 180 cases with solicitors of crew working on military helicopters who have contracted cancers, many like those of the two people I mentioned. They worked on the Sea King particularly, but also the Westland Wessex, the Puma, and the CH-47 Chinook. Many of the crew affected were in touch with each other, as there seemed too many of them, and the cancers too rare, to be pure coincidence.

Last July, a report was written by the Independent Medical Expert Group on medical and scientific aspects of the armed forces compensation scheme, and was published in November last year. There was a section at the end on the potential link between exhaust fumes such as benzene from helicopters and blood cancers such as multiple myeloma. The findings were that the evidence and data available did not meet their threshold to establish a causal link between Sea King helicopter exhaust fumes or benzene and multiple myeloma, leiomyosarcoma, and soft tissue sarcomas.

Unfortunately, we do not have a timescale at the moment. The scale of the task is hard to define. In terms of where the records sit, no one keeps records on veterans when they leave, apart from the NHS. Those records are held in different buckets all over the UK. It is going to take some time to pull that together and analyse it, and to work out whether there are pockets of very rare cancers from one part of defence, another part of defence or from other industries. Unfortunately, we just do not know. I will endeavour to get back to my hon. Friend once the scale of the task, which is gigantic, is conceptualised into time.

I come back to some points raised by my hon. Friend the Member for Truro and Falmouth. On spreading awareness of a potential link, we work really hard to ensure that all service personnel have access to national cancer screening programmes. The MOD regularly runs health education campaigns—I hope that answers her earlier question—that encourage participation in national cancer screening programmes and raise awareness about cancers. Any veteran listening to this debate who has a cancer or a suspicion of cancer should please ensure they get it checked out and get the details recorded medically so that, if there may be a claim of any shape or form, that can be processed and they have the evidence, and it can get dealt with in the fastest and most efficient manner.

Educating GPs in places where there are clusters of personnel and veterans also goes back to data. There are clusters of veterans everywhere, ranging from 1,000 to 17,000, to 33,000 in Portsmouth. I will refrain from speaking about healthcare professionals any broader than the MOD in this forum, but I expect every defence medical service doctor to work in accordance with best practice, particularly National Institute for Health and Care Excellence guidelines, to identify individuals with symptoms that could be caused by cancer and to arrange the appropriate speedy follow-up for a specialist referral.

As well as signposting for veterans, a screening scheme for blood cancers could be set up for those who may be at most risk; that point was mentioned earlier. The current medical advice from IMEG is clear, but I am mindful that there is also no UK screening programme for multiple myeloma or other rare cancers. I have read some of the medical advice, and it looks like some of those screening processes can cause a percentage of harm—I will need to look at that in a bit more detail. Any harm from screening must be outweighed by the benefits of screening. I go back to causation, and a focus on getting data on who needs to be screened and who does not. This is a deeply complex problem. I am not trying to confuse or confuddle the debate. We need to get to the bottom of this, but we need to do it the right way, and in the speediest, most efficient way.

The real-life replication of testing conditions was also mentioned. I want to reassure hon. Members that the testing we do on aircraft mirrors real life. In some cases, it is on the sampling equipment that is carried on the person, on the air crew and indeed the ground crew as well, because not just the pilots are involved, but the broader group. On whether they should still be advised to take sufficient precautions, I should say that I have spent a large proportion of my career in helicopters and stood in the exhaust fumes, which often used to heat us up in cold environments, which I would not recommend. I can attest to the quality and professionalism of the air crew. Indeed, the air crew as a whole are absolutely prepared with both PPE and understanding.

[Mr Dhesi]

I thank the Minister for his clarification about the testing of helicopters currently in service. But could he clarify something? Are there any provisions to conduct tests or derive data on previous models and those not in service?

[Al Carns]

I thank my hon. Friend for the question. Several studies were conducted on the Sea King. In 2010 a study was conducted during operational flying in Afghanistan—I was out there at the same time and probably on them every now and again. It found notable levels of exposure to carbon monoxide and nitrogen monoxide. However, all exposures were below levels considered to be harmful to health.

In 2013, there was a study on search and rescue Sea Kings that found exhaust gases were below levels considered harmful to health. A 2014 study measured exposure to elements of carbon. That was found to be well below the German exposure standard; unfortunately, no UK standard existed at the time. The highest exposure was found to be at least less than a third of the concentration at which, based on the scientific knowledge, long-term repeated exposure could potentially cause ill health.

On the private companies and countries that still use these aircraft, the previous testing of the Sea King helicopters, which I just mentioned, did not have conclusive evidence that air crew were exposed to substances above UK-wide international limits—those German studies. Third party operators and countries may operate the aircraft differently and for different purposes, but I agree with my hon. Friend the Member for Truro and Falmouth that they should ensure that they appropriately manage potential risks. I think we can help with that.

Although views differ, some of the evidence is over a long period of time. The subject group is huge, but it could be quite concentrated in some areas. I accept that we differ on some of the points today. I think we are united in our commitment to the health and safety of our armed forces and the protection of our people, our territories, our values, and indeed our interests, both at home and overseas. It is the most fundamental duty of defence. But that duty is only as strong as the people who uphold it. Our armed forces are not just a source of national pride; they are the lifeblood of our security, admired across the globe for their expertise, professionalism and unwavering commitment. Together we will ensure that the Ministry of Defence remains steadfast in its commitment to the health and safety of its people. Their safety is non-negotiable. Their wellbeing is not optional. It is an obligation.

I want to be clear that we are conducting testing now. We have looked at the reviews of previous testing, and there are options for understanding the broader cancer demographic among our veterans population. I have taken that on after the discussions with my hon. Friend the Member for Truro and Falmouth. We will do everything in our power to ensure that everyone who wears the uniform of this country is protected, respected and supported, because they deserve nothing less.

Question put and agreed to.

Oral Answers to Questions

Tanmanjeet Singh Dhesi Excerpts

Monday 30th June 2025 Commons Chamber

[Mr Speaker]

I call the Chair of the Defence Committee.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

UK defence companies need certainty from the Government in order to invest and plan with confidence. I welcome the Prime Minister’s recent efforts at the G7 and NATO summits, and his commitment to spend 5% of GDP on defence by 2035, including 1.5% on defence and security-related investment. Can the Secretary of State clarify how exactly that 1.5% will be measured? Will it involve new projects and investments, or will it merely be a reclassification of existing projects? Crucially, how can industry, public bodies and other stakeholders contribute so that they can help to achieve that goal?

[John Healey]

My hon. Friend asks characteristically searching questions, so let me send him the NATO criteria that were published alongside the pledge last week, and let him and his Committee, when they interrogate me on Wednesday afternoon, pursue any further questions that they might have.

Armed Forces Commissioner Bill

Tanmanjeet Singh Dhesi Excerpts

Consideration of Lords amendments
Tuesday 3rd June 2025 Commons Chamber

[Madam Deputy Speaker (Caroline Nokes)]

I call the Chair of the Defence Committee.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

As we consider the Lords amendments to the Bill, I welcome the opportunity to reflect on the progress made and the important issues that these amendments address.

I am pleased to support Lords amendments 1, 4, 5 and 6, which enhance parliamentary oversight of secondary legislation under the Bill. The Government’s support for those amendments is a positive step towards greater transparency and accountability in the implementation of this important legislation.

I also want to highlight the significance of whistleblower protection. Lords amendments 2 and 3 rightly draw attention to the need to safeguard those who come forward with concerns. I welcome His Majesty’s official Opposition’s efforts to bring attention to this issue and to the Government’s commitment to this principle, particularly through the amendments they have tabled in lieu, which aim to protect the anonymity of individuals making complaints. That is essential for fostering a culture of openness and trust within our armed forces and ensuring the Armed Forces Commissioner has the confidence of serving personnel and those who make complaints.

I am grateful to the Armed Forces Minister for his clarification on the matter just now. As Chair of the Defence Committee, I want to reiterate that our Committee very much looks forward to holding a pre-appointment hearing with the Secretary of State’s preferred candidate for the first Armed Forces Commissioner—a vital step in ensuring the independence and effectiveness of this new office.

Finally, as this is likely our last opportunity to debate the Bill in the House, I look forward to its passage into law and thank all those who have been involved in drafting and amending the Bill as it has made its way through both Houses.

[Madam Deputy Speaker]

I call the Liberal Democrat spokesperson.

Strategic Defence Review

Tanmanjeet Singh Dhesi Excerpts

Monday 2nd June 2025 Commons Chamber

[Mr Speaker]

I call the Chair of the Select Committee.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

Given the growing instability in Europe and beyond, and the fact that, among other things, the UK is the third most targeted nation on the planet by cyber-attacks, I wholeheartedly welcome the Government’s intention to turn the tanker around and increase the focus on defence. However, the strategic defence review is only as effective as the spending review that will follow this month. To ensure that this SDR does not suffer the fate that has befallen some of its predecessors, how confident is my right hon. Friend the Defence Secretary that his and the Prime Minister’s ambitions will be fully matched with a correspondingly ambitious spending review?

[John Healey]

My hon. Friend rightly raises the scale and nature of the increasing cyber-attacks that this country faces. When I had the privilege of taking this job 10 months ago, I was taken aback to find that in the last year, defence across the piece had been subject to more than 90,000 cyber-attacks that could be linked directly to other states. That is why in this SDR, we pick up the recommendation to establish a new cyber-command, so that we can build on the pockets of excellence across defence and ensure that we can more effectively defend against and use offensive cyber to deter such attacks.

On funding, the spending review next week is an important moment for the Government, but the Prime Minister settled the funding for defence in his statement in February. The Chancellor has already put an extra £5 billion into the defence budget this year. We will hit 2.5% of GDP three years before anybody expected us to, and we have an ambition to hit 3% in the next Parliament. As the Prime Minister confirmed this morning, we will spend what is needed to deliver the vision of the strategic defence review over the next 10 years and beyond.

UK Nuclear Deterrent

Tanmanjeet Singh Dhesi Excerpts

Monday 2nd June 2025 Commons Chamber

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

(Urgent Question): To ask the Secretary of State for Defence if he will make a statement on the future of the UK’s nuclear deterrent.

[The Minister for the Armed Forces (Luke Pollard)]

I am grateful to my hon. Friend the Chair of the Defence Committee for this chance to set out the Government’s total commitment to the UK’s nuclear deterrent, which has been the bedrock of our national security for nearly 70 years. My right hon. Friend the Defence Secretary will shortly outline the details of the strategic defence review to the House, and that review will be underpinned by our nuclear deterrent, which is part of our blueprint for a new hybrid Navy, in which next-generation Dreadnought nuclear-armed submarines, and up to 12 SSN-AUKUS conventionally armed nuclear-powered submarines, will serve alongside best-in-class warships, support ships and new cutting-edge autonomous vessels, building on the £15 billion investment set out for the UK’s sovereign nuclear warhead programme in this Parliament. This is not only a manifesto promise delivered; it is our most important military capability secured for generations to come. This investment will also deliver a defence dividend of highly skilled, well-paid jobs across the country. Our nuclear warhead programme alone will create and sustain over 9,000 jobs, along with thousands more in supply chains.

To ensure that the demands of our nuclear programme can be met, we are working closely with industry partners, and are aiming to double defence and civil nuclear apprenticeship and graduate intakes. That will mean 30,000 apprentices over the next 10 years; they will be part of this historic renewal of our nuclear deterrent and our communities across the country.

The first duty of every Government is to keep their people safe. In a more dangerous world, peace and security are best achieved through deterrence and preparedness. As the son of a Royal Navy submariner, I thank our outstanding submariners who patrol 24/7 to keep us and our allies safe. We know that threats are increasing, and we must act decisively to face down Russian aggression in particular. Our nuclear deterrent is the ultimate guarantor of our security. The Defence Secretary will momentarily make a statement giving further details, but our proposals are possible only because of the Government’s historic decision to increase defence spending to 2.5% of our GDP by 2027—the largest sustained increase in defence spending since the end of the cold war. The Government have the will, the plan and the means to secure the nuclear deterrent for generations to come. We are making Britain secure at home and strong abroad.

[Mr Dhesi]

I thank the Minister for his response, and your good self, Mr Speaker, for kindly granting the urgent question.

Following the report in The Sunday Times that the Ministry of Defence is looking to purchase American fighter jets that are capable of deploying tactical nuclear weapons, it is essential that the House gets clarity on the Government’s nuclear deterrent policy—an issue of critical national importance. How have the media got hold of such sensitive information on future nuclear deterrent plans, and what steps are the Government taking to investigate the leak?

If the Government are pursuing an air-launched tactical nuclear capability, that is a huge deal. It would represent a significant shift in the UK’s nuclear posture. Indeed, it would be the UK’s most significant defence expansion since the cold war. This raises serious concerns about our sovereignty when it comes to nuclear weapons, about strategic coherence with our current doctrine, and about the principle of continuous at-sea deterrence.

Despite the defence nuclear enterprise accounting for around 20% of the defence budget, it remains largely outside meaningful parliamentary scrutiny, including by our Defence Committee. This must change, so will my hon. Friend the Minister explain how Parliament will be enabled to scrutinise changes to the UK’s nuclear programmes? Have discussions taken place with the US, and what role would it play in this capability? Will the Minister confirm that the UK will retain full operational control over any nuclear weapons? Given that tactical nuclear weapons lower the threshold for nuclear weapon use, what assessment has been made of the risks of escalation? Will the Minister confirm that only the Prime Minister would have authority to use them, and only in extreme self-defence? Finally, has there been consultation with NATO allies on this potential shift? Decisions of this magnitude must be transparent. The future of our nuclear deterrent must be based on clarity, credibility and, above all, British control.

[Luke Pollard]

I do not want to eat the Secretary of State’s sandwiches, and I am acutely aware that the statement that he is about to make—

UK Airstrike: Houthi Military Facility

Tanmanjeet Singh Dhesi Excerpts

Wednesday 30th April 2025 Commons Chamber

[Mr Speaker]

I call the Chair of the Select Committee.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

I am grateful to the Secretary of State for his statement and to the Minister for the Armed Forces for his in-person briefing beforehand.

I am glad that our brave service personnel who were involved in yesterday’s strike have returned home safely, and that the precision sovereign strike has destroyed the drone factory with no civilian casualties. I agree with the Secretary of State that Houthi attacks since 2023 have tragically killed innocent merchant mariners, led to a shocking 55% drop in shipping through the Red sea costing billions, fuelled regional instability, and exacerbated the cost of living crisis here in the UK and across the globe. However, on the basis of current intelligence, how confident is he that following yesterday’s strike there will be freedom of navigation and that there will be no further loss of life because of the Houthis?

[John Healey]

I am grateful for my hon. Friend’s support for the action that we took overnight. It was part of a sustained campaign—a US campaign that we are working alongside. There is no overnight solution to this, but according to the evidence reported by the US military about this new sustained, intensive campaign, it seems to be having an effect on the pace, the rate, and the threat that the Houthis pose. Our action last night was designed to reinforce that campaign, to support the push for regional stability, and to protect the domestic economy and protect against the impact of the disruption in international shipping and its effect on prices for ordinary people.

Ukraine Update

Tanmanjeet Singh Dhesi Excerpts

Tuesday 22nd April 2025 Commons Chamber

[Mr Speaker]

I call the Chair of the Defence Committee.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

Although it was saddening to hear about the continued colossal death and destruction in Ukraine, I welcome the Secretary of State’s statement. Indeed, I welcome his leadership of the Ukraine defence contact group, which by pledging a record €21 billion, has demonstrated that the 51 allies are firmly committed to helping our Ukrainian friends in their hour of need. He mentioned the many shorter ceasefires that were agreed and then broken, and the question we need to ask ourselves is: when President Putin says he wants a ceasefire, is that actually the case? However, if a much-needed ceasefire is agreed, how confident is the Secretary of State of convening and then keeping the coalition of the willing together?

[John Healey]

I am grateful to my hon. Friend for his question, and for the job he does in chairing the Defence Committee. One of the trickiest tasks in the work undertaken by our military planners is that it is not clear in what circumstances any forces may be required to be deployed, and it is not clear that the details of the negotiated peace deal we all want to see will be in place. He asked me a straight question, and when the deal is done, the peace is negotiated and the ceasefire is in place, I believe it will actually be easier, not harder, to hold together and enlarge the number of nations willing to be a part of the coalition of the willing. In the meeting I chaired at NATO headquarters 10 days ago—the first ever meeting of the Defence Ministers of the coalition of the willing—the 30 nations around the table, all participating in the detailed operational military planning that is continuing, were not just from Europe but beyond.

Royal British Legion

Tanmanjeet Singh Dhesi Excerpts

Tuesday 1st April 2025 Westminster Hall

[Steve Yemm (Mansfield) (Lab)]

It is a pleasure to serve under your chairmanship, Sir Jeremy. As someone who has spoken many times in the House about the importance of supporting those who have served in our armed forces, I warmly congratulate the hon. Member for Hinckley and Bosworth (Dr Evans) on securing this important debate.

The Royal British Legion does so much behind the scenes to support our veterans. I am proud to say that we have a long-standing Mansfield branch of the Royal British Legion, established on 9 October 1921. As Mansfield’s Member of Parliament, I do everything I can to support the work of the RBL locally. It is important that we all do everything we can to ensure that its activities continue in every one of our constituencies.

That is the reason I was very disappointed to hear recently that our Armed Forces Day commemorations, which that usually take place each year in Mansfield, have been cancelled. The commemoration is enjoyed by families from right across the constituency, including my own. Many have written to me to express their disappointment. I hope therefore that the local parties to this event, including Mansfield district council and the Mansfield business improvement district, will get together and resolve the matter without delay to the satisfaction of the RBL, which has written to me to express its disappointment—as, of course, have many of my constituents.

It is important that we all play our part to support our armed forces personnel, not just through the RBL, but through all the incredible charities and organisations that support our veteran communities.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

Members have rightly raised the invaluable work of their Royal British Legion local branches. I too would like to extol the virtues of RBL Cippenham in Slough and in particular the Berkshire poppy appeal, which does exceptional work in Slough. Most recently, I welcomed the RBL director general to give evidence to the Defence Committee so that we could learn more about the RBL’s national work. Does my hon. Friend agree that the amazing work the RBL does makes it a lifeline for many of our serving members, veterans and their families, and it deserves our recognition and support?

[Steve Yemm]

I could not agree more with my hon. Friend. Certainly in my own constituency, I see many of those things the RBL does behind the scenes, such as helping those living at home, assisting with personal casework issues, providing grants, ensuring veterans are getting the appropriate war pensions they are entitled to, and so forth. I certainly agree it is a lifeline. Given that we all believe the RBL does great work in our communities, I certainly promise that, for as long as I am the Member of Parliament for Mansfield, I will do everything I can to ensure that in my constituency we support the RBL and we never forget.

Oral Answers to Questions

Tanmanjeet Singh Dhesi Excerpts

Monday 24th March 2025 Commons Chamber

[Mr Speaker]

I call the Chair of the Select Committee.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

With escalating threats to our critical infrastructure, I was concerned by reports over the weekend that our armed forces chiefs are apparently being gagged over the upcoming strategic defence review, which has been described by some as “limp”. I am fully aware that, recognising the dangers, the Government have announced the largest increase in defence spending since the end of the second world war, but at this critical time we certainly should not be sidelining our service chiefs or penny-pinching on our nation’s defence. Would the Minister like to take this opportunity to reassure the nation that our strategic defence review, when published, will be bold, ambitious and anything but limp?

[Luke Pollard]

Absolutely. We live in incredibly difficult times, which is why this Government are meeting the moment with increased defence spending and the biggest reform of our defence in 50 years. We are investing in new technologies, and investing in the people who keep our country safe. From the most senior generals and admirals down to privates and sailors, we are giving all our armed forces a renewed determination to make sure they understand how we defend our country in its best interests, but also that the nation backs them in defending our country. There are further announcements to come, but let us all be in no doubt but that the whole House backs our armed forces and that we look forward to the further investment in defence that is coming.

Cadet Forces

Tanmanjeet Singh Dhesi Excerpts

Wednesday 29th January 2025 Westminster Hall

[Peter Swallow]

I will touch on many of the points made by the right hon. Member, but her intervention really shows that the commitment to our cadets and the volunteers who support them is felt across the House.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

I thank my hon. Friend for securing this debate on cadet forces. In Slough, we have the Sea Cadets, Air Cadets and Army Cadets, which provide a fantastic development and learning opportunity for young people as well as playing an invaluable part in community events and services. Does my hon. Friend agree that we need to ensure that the cadet expansion programme is sufficiently funded, so that more young people can benefit from the amazing opportunities provided by being a cadet?

[Peter Swallow]

My hon. Friend speaks with great weight on this topic as the Chair of the Defence Committee. In that role, it is important that he recognises the huge contribution of not only our armed forces, but the cadets, so I welcome him taking part in this debate.

I will come on to the cadet expansion scheme later in my speech, but it is really important that we think about expanding all cadet forces, not just Combined Cadet Forces, although they are important. The cadet expansion scheme is very much targeted at CCF, so I would like to see it being well funded and looking across the five cadet forces.
