PARLIAMENTARY DEBATE
Strategic Defence Review - 2 June 2025 (Commons/Commons Chamber)
Debate Detail
The world has changed, and we must respond. The SDR is our Plan for Change for defence: a plan to meet the threats that we face, a plan to step up on European security and to lead in NATO, a plan that learns the lessons from Ukraine, a plan to seize the defence dividend resulting from our record increase in defence investment and boost jobs and growth throughout the United Kingdom, and a plan to put the men and women of our armed forces at the heart of our defence plans, with better pay, better kit and better housing. Through the SDR, we will make our armed forces stronger and the British people safer.
I thank those who led the review, Lord Robertson of Port Ellen, General Barrons and Dr Fiona Hill,
“a politician, a soldier and a foreign policy expert”,
as they describe themselves in their foreword. They, alongside others, have put in a huge effort. This is a “first of its kind”, externally led review, the result of a process in which we received 8,000 submissions from experts, individuals, organisations and Members on both sides of the House, including the shadow Defence Secretary. I thank them all, and I thank those in the Ministry of Defence who contributed to this SDR. It is not just the Government’s defence review, but Britain’s defence review. The Government endorse its vision and accept its 62 recommendations, which will be implemented.
The threats that we face are now more serious and less predictable than at any time since the end of the cold war. We face war in Europe, growing Russian aggression, new nuclear risks, and daily cyber-attacks at home. Our adversaries are working more in alliance with one another, while technology is changing the way in which war is fought. We are living in a new era of threat, which demands a new era for UK defence. Since the general election we have demonstrated that we are a Government dedicated to delivering for defence. We have committed ourselves to the largest sustained increase in defence spending since the end of the cold war, with an extra £5 billion this year and 2.5% of GDP in 2027, and the ambition to hit 3% in the next Parliament. However, there can be no investment without reform, and we are already driving the deepest reforms of defence in 50 years. Those reforms will ensure clearer responsibilities, better delivery, stronger budget control and new efficiencies worth £6 billion in this Parliament, all of which will be reinvested directly in defence.
Our armed forces will always do what is needed to keep the nation safe, 24/7, in more than 50 countries around the world; but in a more dangerous world, as the SDR confirms, we must move to warfighting readiness, and warfighting readiness means stronger deterrence. We need stronger deterrence to avoid the huge costs, human and economic, that wars create, and we prevent wars by being strong enough to fight and win them. That is what has made NATO the most successful defence alliance in history over the last 75 years. We will establish a new “hybrid Navy” by building Dreadnought, AUKUS submarines, cutting-edge warships and new autonomous vessels. Our carriers will carry the first hybrid airwings in Europe. We will develop the next generation Royal Air Force with F-35s, upgraded Typhoons, sixth-generation Global Combat Air Programme jets and autonomous fighters to defend Britain’s skies and to be able to strike anywhere in the world, and we will make the British Army 10 times more lethal by combining the future technology of drones, autonomy and artificial intelligence with the heavy metal of tanks and artillery.
For too long, our Army has been asked to do more with less. We inherited a long-running recruitment crisis, following 14 years of Tory cuts to full-time troops. Reversing the decline will take time, but we are acting to stem the loss and aiming to increase the British Army to at least 76,000 full-time soldiers in the next Parliament. For the first time in a generation, we have a Government who want the number of regular soldiers to rise. This Government will protect our island home by committing £1 billion in new funding to homeland air and missile defences, creating a new cyber-command to defend Britain in the grey zone, and preparing legislation to improve defence readiness.
As Ukraine shows, a country’s armed forces are only as strong as the industry that stands behind them, so this SDR begins a new partnership with industry, innovators and investors. We will make defence an engine for growth to create jobs and increase prosperity in every nation and region of the UK. Take our nuclear enterprise. We will commit to investing £15 billion in the sovereign warhead programme in this Parliament, supporting over 9,000 jobs. We will establish continuous submarine production through investments in Barrow and Derby that will enable us to produce a submarine every 18 months, allowing us to grow our nuclear attack fleet to up to 12 submarines and supporting more than 20,000 jobs. On munitions, we will invest £6 billion in this Parliament, including in six new munitions factories and in up to 7,000 new long-range weapons, supporting nearly 2,000 jobs. The lives of workers in Barrow, Derby and Govan, where the Prime Minister and I were this morning, are being transformed not just by this defence investment but by the pride and purpose that comes with defence work. In the coming years, more communities and more working people will benefit from the defence dividend that this SDR brings.
Ukraine also tells us that whoever gets new technology into the hands of their armed forces the fastest will have the advantage, so we will place Britain at the leading edge of innovation in NATO. We will double investment in autonomous systems in this Parliament, invest more than £1 billion to integrate our armed forces through a new digital targeting web, and finance a £400 million UK defence innovation organisation. To ensure that Britain gains the maximum benefit from what we invent and produce in this country, we will create a new defence exports office in the MOD, driving exports to our allies and driving growth at home.
The SDR sets a new vision and a new framework for defence investment. The work to confirm a new defence investment plan, which will supersede the last Government’s defence equipment plan, will be completed in the autumn. It will ensure that our frontline forces get what they need, when they need it. The plan will be deliverable and affordable, and it will consider infrastructure alongside capabilities. It will seize the opportunities of advanced tech, and seize the opportunities to grow the British economy.
As we lose the national service generation, fewer families across this country will have a direct connection to the armed forces, so we must do more to reconnect the nation with those who defend us. As the SDR recommends, we will increase the number of cadets by 30%, introduce a voluntary “gap year” scheme for school and college leavers, and develop a new strategic reserve by 2030. We must also renew the nation’s contract with those who serve. We have already awarded the biggest pay increase in over 20 years and an inflation-busting increase this year, and now I have announced that we will invest £7 billion of funding during this Parliament for military accommodation, including £1.5 billion of new money for rapid work to deal with the scandal of military family homes.
This SDR is the first defence review in a generation for growth and for transformation in UK defence. It will end the 14 years of the hollowing out of our armed forces. Instead, we will see investment increased, the Navy expanded, the Army grown, the Air Force upgraded, warfighting readiness restored, NATO strengthened, the nuclear deterrent guaranteed, advanced technology developed, and jobs created in every nation and region of this country. The strategic defence review will make Britain safer, more secure at home and stronger abroad.
“We were not offered a briefing”,
and
“We had no advance copy of the defence review.”—[Interruption.]
While the Government may have tried to hide the document from us for as long as possible today, they cannot hide what has happened in plain sight, which is a total unravelling of their strategic defence review because, quite simply, they do not have a plan to fund it. An SDR without the funding is an empty wish list. The ships and submarines it talks of are a fantasy fleet. The reviewers were clear in The Telegraph today that the commitment to 3% “established” the affordability of the plan. On Thursday, the Defence Secretary said in an interview with The Times that reaching 3% was a “certainty”, but by the weekend he had completely backtracked to 3% being just an “ambition”. Today, the Prime Minister was unable to give a date by which 3% would be reached. Why? Because the Treasury has not approved a plan to pay for it.
The Secretary of State and I have both been Treasury Ministers and Defence Ministers, and he knows as well as I do how this works. For the Treasury to approve a plan, it will have to feature billions of pounds of cuts to existing MOD programmes, so this SDR has dodged the big decisions on existing capabilities. Can the Secretary of State confirm that the so-called defence investment plan to be published in the autumn will set out the cuts needed for the Treasury to agree a plan to get to 3%? We should have had those details in the SDR today.
Can the Secretary of State also confirm that the total budget for new measures announced in this SDR over the next five years is less than £10 billion? That is less than we will be spending to lease back our own base on Diego Garcia. Is it not the hard truth that the Government are unable to guarantee the money our armed forces need, but the one plan they can guarantee is to give billions to Mauritius for land we currently own freehold? And can he finally tell us what percentage of the payment for Chagos will be met by the MOD? He has never told us before.
Let me suggest an alternative path to the Secretary of State: first, guaranteeing to hit 3% and doing so in this Parliament, not the next; secondly, getting a grip on our welfare budget, rather than competing with Reform to expand it; thirdly, saving billions by scrapping their crazy Chagos plan. That is a plan to back our armed forces and make our country stronger from the party that actually last spent 3%, in 1996. The terrible shame of this SDR unravelling is that this was an extraordinary—[Interruption.] It was a Labour Government who came in, in 1997; I do not know what Labour Members are laughing about. The terrible shame of this SDR unravelling is that this was an extraordinary opportunity to overhaul our armed forces in a world of growing threats.
Only yesterday, we saw the Ukrainians once again demonstrating, with their audacious attack on Russian nuclear bombers, how profoundly war has changed. And yet it is true that some of the best long-range one-way attack drones used in Ukraine have not been built by Ukraine, but by UK defence SMEs. We are incredibly well placed to be a leading nation in the development of uncrewed forces, but how many military drones have the Government actually purchased for our own military since the general election? In a written answer to me, the answer was not 3,000 or 300, but three. They have purchased three reconnaissance drones since the election and not a single one-way attack drone. That is the reality. For the past year, the Treasury has used the SDR to effectively put MOD procurement on hold. That is absolutely shameful when we need to rearm at pace and at scale. At least the Secretary of State for Defence knows how the rest of the country feels: totally let down by the Chancellor of the Exchequer.
If there is one capability that matters more than any other, it is people. We agree on the critical importance of recruitment and retention, which is why I did so much of the work to buy back the defence estate so we could rebuild it and rebuild the substandard defence accommodation. But the Army is down by 1,000 since the election. If the Government really want to address recruitment and retention, would it not be total madness to scrap the legislation protecting our Northern Ireland veterans from a new era of ambulance-chasing lawfare? Surely nothing could be more damaging for morale, recruitment and retention than to once again pursue our veterans for the crime of serving this country and keeping us safe from terrorism.
To conclude, the Secretary of State says he wants to send a strong message to Moscow, but the messages he is sending are profoundly weak: surrendering our fishing grounds for an EU defence pact that does not offer a penny in return; surrendering the Chagos islands, to the delight of China and Iran; surrendering our Army veterans to the lawyers; and to cap it all and after so much hype, producing a damp squib SDR that is overdue, underfunded and totally underwhelming. Our armed forces deserve a lot better than this.
The shadow Secretary of State talks about unfunded promises. He knows about unfunded promises. His drone strategy was unfunded. It was 12 pages, with more pictures than words. His munitions strategy was unfunded and even unpublished. His party’s commitment to 2.5% on defence was never in Government Budgets. It was a gimmick launched four weeks before they called the election—they dither, we deliver.
On Diego Garcia, I say this to the shadow Defence Secretary. This deal is a great investment in the defence and intelligence base that we share with the Americans. It is essential for activities that cannot be undertaken elsewhere, and that we do not undertake with any other nation. It is a deal worth 0.2% of the defence budget. The US backs the deal. NATO backs the deal. Five Eyes backs the deal. Australia backs the deal. India backs the deal. So how, on this national security issue, have the Opposition got themselves on the wrong side?
As far as the SDR goes, this is the defence moment of a generation. With threats increasing and defence spending rising, we now have a plan for transformation—a plan that will link the best of advanced technology with the heavy metal of our platforms; a plan that will drive the defence dividend to increase jobs and business support across the country; and a plan that puts people in defence right at the heart of our defence plans for the future, with increased pay, better housing and better kit to do the job of deterring our adversaries.
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.
The Defence Secretary and the Prime Minister are absolutely right. We have entered a new era—one defined by international instability, geopolitical conflict and global uncertainty. Perhaps not since the end of the cold war have we faced such myriad threats to our defence: a barbaric Russian imperialism under Putin threatening Ukraine’s freedom and NATO’s security; a Trumpian White House defined by its total indifference to, and even antagonism towards, the defence of Europe; and the rising threat posed by China, as well as by regional pariah states such as Iran and North Korea. Taken together, these threats pose a once-in-a-generation risk to our country’s defence. Meeting generational risks will require making generational commitments, so I welcome the Government’s readiness to accept all the recommendations outlined in today’s strategic defence review.
It is frankly staggering, however, that we still do not have a clear answer to the vital question: where is the money coming from to fund these ambitions? This is a shopping list without the money to pay for it. The Government have flip-flopped on whether we can expect defence spending to rise to 3% of GDP—the figure on which the proposals of the SDR are premised. Putting the cart before the horse when it comes to funding the nation’s defence sends entirely the wrong message to Putin and our other adversaries. Will the Secretary of State commit to holding cross-party talks on how to reach 3%?
While I welcome the announcement of new funding for military housing and urgent repairs, fixing our recruitment crisis and doing right by our service personnel requires more than sticking-plasters. Will the Government legislate to require all military homes to be brought under the decent homes standard? It is desperately disappointing that despite having had 11 months to consider how to stem the decline in the number of soldiers in the Army, the Government appear to have sat on their hands. The shameful decline in troop numbers has only continued on their watch. Does the Secretary of State agree that if the Government are serious about delivering for Britain’s defence, reversing the utterly reckless troop cuts overseen by the Conservatives must begin now?
The SDR is a vision for the next 10 years and beyond. It can be delivered within the spending commitments that this Government have made. As the Prime Minister underlined this morning, those spending commitments were baked into the terms of reference, and have been confirmed by the reviewers. As he has said, we will spend what we need to deliver this review, and I am totally confident that we will meet the ambition of 3% in the next Parliament.
On military homes, the hon. Lady is right to mention the scandal, which has gone on for years, of making the families of those who serve live in substandard homes, which are often mouldy and damp, with leaking roofs and doors. We can change that, and we have acted to start to do that. This year, for the first time, we bought back family military homes, and we now control 36,000 of them. Last month, also for the first time, we set out a consumer charter, with the basics of what people can expect from the MOD as their landlord. We have also confirmed an extra £1.5 billion over this Parliament to deal with the worst military family homes. We can start to develop for the long term, and build the homes that we need for our forces, and in the country more widely. We will be able to use better the huge asset that MOD land offers.
I really welcome this review from the Secretary of State. I have been around long enough to have seen the words “review”, “defence”, “strategic” and “modern” used many times. As the Secretary of State highlighted, the nadir was reached when the right hon. Member for Stone, Great Wyrley and Penkridge (Sir Gavin Williamson) was Secretary of State, in a report that had more pictures than text. This report will live only if all Members of this House agree that it is long term, because as the Secretary of State knows, chopping and changing and stopping and starting programmes can cause real problems for our men and women on the ground. Does the Secretary of State agree, and what is he doing to make sure that we embed the review for the long term?
I also welcome my hon. Friend’s chairwomanship of the Treasury Committee. I hope that her Committee will take an interest in the defence investment at the heart of the SDR and at the heart of our plans. The record defence investment that the Government are making in this country not only reinforces our national security, but can drive economic growth and bring a defence dividend that will drive the mission of this Government to increase economic growth and bring jobs, business and new tech to every part of the country.
We will succeed to the extent that we have a Government ready to invest, and a town in Barrow and a supply chain of proud workers from across the UK who are willing to lend their professional expertise to this most important mission: securing our nation’s defences for the future; contributing to a stronger NATO; and reinforcing our ability to generate jobs and prosperity, including in Barrow.
“pull latest technology into operations”,
and to
“unlock private equity and venture capital”.
My question is this: do we need to change the commercial competition laws within the civil service to allow that to happen, or can it already happen?
The hon. Gentleman is also right that it is the people who are at the heart of this. He will recognise the 14 years of failure leading to the recruitment and retention crisis that we were left with last summer. He will know that I have removed over 100 of the rules that prevented some people from applying to join the forces. He will know that I have introduced direct entry for those with cyber talent to join and contribute to our defences. He will also recognise that we are looking to retain those who are valuable to us by paying better, by looking to upgrade the housing and, where needed, through special retention payments.
This is going to take time. We are closing the gap and I am determined that we will reverse that long-term decline. For the first time, this is a Government who want to increase, not further cut, the size of our Army.
“We will develop a new Defence Investment Plan”.
However, as the Secretary of State knows from all the Budgets and fiscal events he has sat through, he cannot give the House a categorical assurance over future spending commitments, so will he make it clear to the House what decisions he is prepared to make with respect to the existing commitments such that he can secure that additional funding at subsequent spending reviews and Budgets? I hope that when he comes clean completely to this House, he will make clear that there will be considerable ongoing investment in the Defence Science and Technology Laboratory at Porton Down, which does an enormous amount to secure understanding of future technologies in the defence arena.
On innovation and the British base, my hon. Friend will recognise that, as part of warfighting readiness, we require an industrial readiness. That industrial readiness—that industrial deterrence that is part of preventing our adversaries from considering attacks against us—means that our companies must be able to innovate and scale up production if we are faced with conflicts in the future. That will be a touchstone for the way we will take many decisions as we invest in the future.
“Defence should only run training and education itself when it cannot be obtained externally at suitable quality and cost.”
I think that ties in with paragraph 4 on page 105:
“As it reconsiders its training estate needs, the Navy should ensure there is ‘capacity by design’”.
I worry that that would mean the closing of the Dartmouth academy. Let me explain why I have linked those two statements. I am sure the Secretary of State has visited the United States naval officer training academy in Annapolis. The model there brings a real fellowship to people who want to stay in the armed forces because of all the things offered through the degrees and so on. I will perhaps expand on those comments when we have a further debate, but will the Secretary of State give a reassurance that great institutions and buildings such as Dartmouth will not be closed under this review?
I say to the hon. Gentleman and to the House that we make an extraordinary contribution as a nation to NATO, and we will step that up through pursuing the SDR vision. Of course, at the heart of it is something we contribute that no other nation does: in full, we commit our UK nuclear deterrent to NATO, as the ultimate guarantor not just of our own national security but of the security of our NATO allies.
On page 32 of the review, an overview of the dependencies and threats includes critical minerals such as lithium. Does the Secretary of State agree that the most effective way to reduce dependency on such critical minerals from the likes of China, is to invest heavily and urgently in domestically produced and processed critical minerals such as tin, lithium and tungsten in Cornwall?
“absolutely vital for our defence and intelligence”
as the Prime Minister claims? He is a former Labour security Minister and current House of Lords representative on the Intelligence and Security Committee, so he knows what he is talking about, doesn’t he?
“this will allow us to grow our nuclear-powered attack submarine fleet to up to 12.”
Is not the truth—and let’s speak the truth—that that is the ask to the Treasury, and the spending review has yet to decide what the defence programme will be? I hear what the Secretary of State says, when he says with his full force and sincerity that “we will fund this defence review”, but how will he achieve that without much more significant cuts to other budgets? No Government can afford to spend and borrow much more, if anything at all, so how will he get the necessary cuts through to fund this big increase in defence spending, beyond 3.5% because we all know we will need more than that?
I also ask the Secretary of State about recommendation 40, which says:
“The Royal Navy should explore alternative approaches to augmenting the Royal Fleet Auxiliary to deliver a balanced, cost-effective fleet that maximises the UK’s warfighting capabilities.”
The RFA is already stretched; I have been on visits to the RFA where it has told me that it is stretched with the operational requirements placed on it. It sounds to me like this is a loss of operational independence. Will the Secretary of State commit to an expansion of the Royal Fleet Auxiliary consisting of ships managed purely by the Royal Navy under the defence estate?
“The connection between the UK Armed Forces and wider society is the longstanding and necessary foundation for the defence of the country.”
In the light of that, will this review reverse the rundown in armed forces personnel in Northern Ireland, where today, according to answers given in this House, there are five Royal Navy and Royal Marines personnel stationed? Of all the services—all three together—there are only 1,305 personnel in Northern Ireland, yet we supply a huge number of personnel to those services. Will the review reverse that rundown and make sure that every part of this United Kingdom shares in the provision of the armed services?
I apologise to hon. Members on both sides of the House that, despite nearly two hours at the Dispatch Box, we have not got to everybody’s question. If any Member wants to raise points with me, they should please do so directly, and I will provide them with answers.
I said earlier that we knew of one major defence company that received a copy of the document at 8 am this morning. I have been told of another major prime—one of the largest—that received a copy at 8 am this morning. That means that at the time that I was messaging the Minister for the Armed Forces and begging him to let us have a copy, and he was saying that we could not have one, they were reading the SDR over breakfast.
Madam Deputy Speaker, you heard Mr Speaker refer to the phrase “skin in the game”; he was very concerned about a document being given early in the morning to big defence companies that have skin in the game. Can you advise us on what more we can do to probe this point and hold the Government to account on commercial sensitivity?
