UK Defence Capability

Lord Stirrup Excerpts

Monday 8th June 2026 Lords Chamber

[Lord Coaker (Lab)]

It has been well reported. I have said from this Dispatch Box, and the First Sea Lord has said it as well, that the availability of submarines is not where the Government would want it to be. That is why we are investing, for example, £4.5 billion in the dockyards in Plymouth. The dockyards in Plymouth need investment, the dockyards in Scotland need investment, and we are looking at that. We are also looking at original ways of seeing whether we can provide docking facilities to increase the availability of submarines by looking at various provisions that do not require building or rebuilding a whole new dock. The noble Lord is quite right to point out that we need to do better on the availability of submarines. Of course we do. We will not comment on exactly how, and the noble Lord would not expect me to, but of course availability needs to improve and we are looking at how we can do that.

[Lord Stirrup (CB)]

My Lords, the focus has been on the defence investment plan, which is, of course, crucial, but does the Minister agree that capability is not just about capital investment? Resources expenditure, which is treated differently, is crucial. It pays for the fuel and spares that our people need to conduct training that is fundamental to their operational capability and it pays their salaries and for the standard of their accommodation. Does he agree that any plan that the Ministry of Defence brings forward that does not fund resource adequately will just continue the hollowing out of our Armed Forces that has taken place over the past two decades?

[Lord Coaker (Lab)]

I thank the noble and gallant Lord for the question. In any investment plan going forward, obviously the emphasis tends to be on capital as the noble and gallant Lord says—how many planes will we have, what we will do with munitions, and those sorts of things. However, he is quite right to point out the resource element of the budget—the day-to-day expenditure that pays for wages, training and all those things—is equally important, otherwise we run into trouble, particularly mid-year if there is a need to rebalance and look how to resource the particulars. The noble and gallant Lord often points out that if we do not get the resource allocation right, it impacts on the morale of the very people who serve our country. He is quite right to point that out. Discussions about the correct split between CDEL and RDEL is also going on.

King’s Speech

Lord Stirrup Excerpts

Thursday 21st May 2026 Lords Chamber

[Lord Stirrup (CB)]

My Lords, in his speech at the Munich Security Conference in February, the Prime Minister warned of the dangerous time in which we live. He went on to say:

“In the 1930s, leaders were too slow to level with the public about the fundamental shift in mindset that was required. So we must work harder today to build consent for the decisions we must take to keep us safe”.


Wise words—which makes the deafening silence that has followed all the more astonishing. Where is the national conversation that we were promised and that is crucial to convincing people, most particularly the younger generation—not to mention the Treasury—of the need to face squarely the perils ahead? At the moment, it is nowhere, and certainly not in the gracious Speech. So perhaps I can help the Minister who will wind up by suggesting some key elements that should underpin such a conversation.

The first is to remind people of what the Athenians taught the Melians during the Peloponnesian war: the strong do what they can and the weak suffer what they must. If we allow ourselves to become weak, our good intentions will count for nothing. The only intentions that will have any meaning will be those of the powerful, and, if those intentions are malign, we will just have to suffer them. The second point is that our strength is directed towards and essential to the deterrence of major conflict. Weakness makes war more, not less, likely—either that or abject surrender to the demands of an aggressor. Effective deterrence is expensive, but a failure of deterrence far more so, and the horrendous costs are then paid in blood as well as in treasure.

Effective deterrence occurs in the mind of a potential adversary: they must be convinced that malign action on their part will result in consequences that will be unacceptable to them and that conflict will result in their defeat, no matter what measures they pursue. They must therefore be clear that we have the full range of capabilities and the political will to ensure such an outcome.

Strength is of course enhanced by acting in concert with others, which is why NATO remains crucial to our security, but membership of an alliance does not absolve us of the need to pull our weight. To our shame, we are slipping well down the weight scales within NATO. Moreover, it makes no sense for NATO to rely upon a single-source supplier for crucial strategic capabilities, as we do upon the United States. This is not just a matter of one unpredictable Administration: come the day they are needed, those capabilities may be unavailable or diminished for all sorts of reasons. NATO needs to be much more resilient to such uncertainties, and this means that European members must develop alternative sources of such strategic capability, most of which will be beyond the reach of any individual nation. European partnerships to fund, develop and operate those capabilities are urgently required, but the capabilities that are necessary for victory will not all be present at the start of any conflict, either in nature or in quantity.

It is notable that many of the systems and methods that the Ukrainians are now employing so successfully against the Russians did not exist four years ago. The lesson here is that we need in Europe an agile, innovative and rapidly scalable industrial base—not, I should note, just traditional defence companies—that can rapidly adapt to the circumstances of a conflict and produce at large scale the technologies crucial to success.

The final point is that properly resourced military forces of appropriate size are essential but not by themselves sufficient for effective deterrence. Our political system, social structure and domestic infrastructure need to be resilient to the attacks they are already suffering, which would increase manifold in the lead-up to and during any conflict. Weakness in this area undermines our deterrent posture. As the Government’s own defence review made clear, we currently have shortfalls in many of the requirements for effective deterrence. We must make good those deficiencies as a matter of urgency, not just articulate vague aspirations for the future. That means fiscal choices that may be hard politically but are obvious in logic. It is a choice between pain now and a likelihood of catastrophe in the future. This is the message our political leaders must take to the country. These are the measures on which they must deliver. Yes, it will be a challenge, but it is one to which they must rise. It is time, indeed beyond time, for them to lead.

Strategic Defence Review: Funding

Lord Stirrup Excerpts

Thursday 16th April 2026 Lords Chamber

[Lord Coaker (Lab)]

There is a debate in Grand Committee on Monday about defence resilience, so we can start the conversation there. Of course, there is a broader conversation that the noble Lord referred to, and we are working hard to deliver that as well. I accept that there is a debate about defence spending. However, in 2024-25, the total DEL was £60.2 billion. In 2028-29, it will be £73.5 billion under current plans. That is a £13.5 billion increase in that final year.

On the SDR, the noble Lord will know, notwithstanding the debate going on around it, that the Government are not waiting for the publication of the SDR. Significant investments are being made already. The Leonardo investment in Yeovil around helicopters was announced recently. Again on helicopters, just yesterday nearly £900 million was announced Boeing UK for Chinook and Apache maintenance. There is huge investment in shipbuilding in Scotland, which is immense for Scotland and something about which we can all be pleased. The nuclear deterrent is being renewed. We have ordered 12 F35As. All those things are important. We are not waiting for the SDR; we are investing already. The debate will no doubt continue on the total amount, but it is wrong to say we are not investing anything.

[Lord Stirrup (CB)]

My Lords, I offer my sympathies to the Minister for being put up, once again, to defend the indefensible. Would he agree that the people of this country have a right to expect their leaders to, well, lead? The need is not in doubt. The Prime Minister goes to places such as Munich and gives very eloquent speeches, setting out the urgency of the requirement, but back at home the issue apparently remains on his desk, where I assume it has been sitting for months. Could the Minister take the message back to his colleagues—it is a message with which I know he agrees, although he cannot say so—that the time for leadership is not now, it is long past? We need to get on with this. The situation is too urgent and too dangerous to permit a further delay.

[Lord Coaker (Lab)]

The DIP is being finalised. As the noble and gallant Lord said, the DIP is on the Prime Minister’s desk, as he said recently at the Liaison Committee, and is being considered. The only point I make to the noble and gallant Lord is the one I made to the noble Lord, Lord Bruce, and often make to the noble Baroness, Lady Goldie. I accept the debate and discussion about the totality of the amount that should or should not be spent within the total the Government have available. Alongside that discussion and debate, significant change is happening and significant investment is being made. The defence budget is rising. I know it is not rising in the way the noble and gallant Lord would wish it to but, as I said to the noble Lord, Lord Bruce, and without repeating it to save time for other noble Lords to ask questions, significant investment is going into the defence industry and defence capabilities across our nation, of which the British public can be proud.

UK Homeland Defence

Lord Stirrup Excerpts

Monday 23rd March 2026 Lords Chamber

[Lord Coaker (Lab)]

Let me deal with two separate issues on that. First, should the UK develop its own sovereign capability and do as much as we can to have the industry and intelligence that we need ourselves? Of course we should. The Government are taking action to rebuild and develop our own capabilities and industry. I have to say, with respect to the US, as the noble Lord has heard me say many times from this Dispatch Box, let us be under no illusions: the US-UK relationship is fundamental to the defence of our nation and fundamental to the protection of our values not only in this country but in Europe and across the world. The intelligence sharing and military-to-military co-operation that takes place is still absolutely essential to the defence of that. I know the noble Lord agrees with that. I will not get into what the President has said or has not said. All I am saying is that, for the intents of defending this country, our alliance with the United States is fundamental, and we should respect it for that.

[Lord Stirrup (CB)]

My Lords, surely the point here is not the threat from Iranian missiles, which would be operating at extreme range with limited payload and very poor accuracy. The lessons to be drawn from this conflict are the vulnerability of military and civilian sites to combined missile and drone attack, which are capabilities Russia has in abundance and the targets set in the UK will be particularly vulnerable to. The Minister has pointed out some of the investment that has been made since the SDR, but it is wholly inadequate to restore the military capability we need to defend these islands and to provide the necessary degree of resilience to such attacks. If the Government do not do something urgently in financing these capabilities correctly, then this country will be vulnerable to such attacks for years to come.

[Lord Coaker (Lab)]

I say to the noble and gallant Lord that, of course, we await the defence investment plan, but we are not waiting for it before we do things. I have pointed out the investment we have made into some air defence systems already, but he is quite right to point out that we need to make progress at pace, as quickly as we can, to defend against potential missile threats but also against drone threats, which he quite rightly points out. We are assessing what we can do, are trying to work at pace on that, and will do all we can to protect our country—which, as everyone says, is the first duty of any Government.

Defence Industrial Strategy 2025: Economic Growth and Job Creation

Lord Stirrup Excerpts

Tuesday 3rd March 2026 Lords Chamber

[Lord Coaker (Lab)]

I agree with that. It is really important for the defence industrial strategy that we liaise with all the devolved Governments and, as my noble friend says, with local devolved councils and mayoral authorities. Kim McGuinness is the Mayor of the North East, in my noble friend’s part of the country, and I know of the work that he has done with local authorities. It is essential that we work with them to deliver the economic growth that we want across all the regions of England and nations of the UK.

[Lord Stirrup (CB)]

My Lords, the defence industrial strategy will have no economic effect. What might make an impact is a defence investment plan, backed up by the necessary level of resources. The absence of such a plan is undermining business confidence and investor confidence. When will the Government start taking such crucial decisions at a pace that matches the urgency of the international situation we face?

[Lord Coaker (Lab)]

I accept the point with respect to the publication of the defence investment plan. As the noble and gallant Lord will know, that will be published as soon as it is ready. Look at what has been happening. Noble Lords across this Chamber demanded that the Government spend money on Leonardos, and we announced investment in them just recently. We have also invested huge sums of money on the Clyde and at Rosyth to build new ships. We are investing huge sums of money to develop the dockyards in Plymouth to improve the availability of the submarines, and we are also making numerous investments, such as in Rolls-Royce, with a £9 billion nuclear programme over the next few years. I understand the point the noble and gallant Lord is making, but the Government are not standing still—we are already spending billions of pounds investing in our defence industry.

Ministry of Defence: Budget Shortfall

Lord Stirrup Excerpts

Thursday 15th January 2026 Lords Chamber

[Lord Coaker (Lab)]

The defence investment plan will deal with choices according to the budget that it has set for it. Even if you increase the budget, you still have to make choices about what you spend that money on. The Chief of the Defence Staff and the other chiefs are involved in this, discussing what capabilities we need, with the budget that we have, to ensure that we have the war-fighting readiness we need. Those choices are taking place.

Considerable sums of money are being spent at present—billions of pounds. I keep repeating this: under current plans, the total budget in 2024-25 was £60.2 billion; in 2008-29, on current plans, it will be £73.5 billion. Billions of pounds of additional money is being spent. We are seeking to ensure that we spend it properly and appropriately to fight the wars of the future.

[Lord Stirrup (CB)]

My Lords, the Minister is quite right, but he knows as well as the rest of us that those are meaningless figures: what really matters is how much you can buy for the money you are spending. Given the accounting changes that have taken place over the intervening years, we are currently spending a lower percentage of GDP on defence than we were in 2010, when we were not facing the very serious threats to European security that we see today. How do the Government explain this?

[Lord Coaker (Lab)]

The Government explain it by using the figures I have just outlined. There is billions of pounds of additional money. You cannot alter the fact that it is going from the figure I just gave to the noble Lord, Lord Young, to the figure it will be. The noble and gallant Lord knows far better than me that choices have to be made within that budget about what capabilities you will spend it upon. One of the choices that confronts us is what lessons we learn from Ukraine, and what capabilities we need to ensure that we fight the war of the future and not the war of the past. That is part of the discussion that is going on at present.

Boarding of Sanctioned Vessels

Lord Stirrup Excerpts

Wednesday 14th January 2026 Lords Chamber

[Lord Coaker (Lab)]

My noble friend heard the careful Answer that I gave to the noble Baroness; I hope that went some way to answering the question that he has posed. It is not as though we have not been doing anything. Let me set out the facts for my noble friend; I asked for them and mentioned them a couple of days ago. As a consequence of sanctions, Russia’s oil revenues are down 27% compared with October 2024 and 544 vessels have had sanctions imposed on them by us, with 200 of these sidelined through actions taken by ourselves and our partners. So I take the noble Lord’s point about the need to go further and faster, but we are taking action, and that action has had some consequence on the Russian war machine.

[Lord Stirrup (CB)]

My Lords, shadow fleets pose a threat not just to the effectiveness of sanctions but to critical undersea infrastructure, and therefore require a more robust response than they have had hitherto. That requires not just expert, trained personnel, which we absolutely have, but the necessary maritime and air support assets, which are much more problematic. It is noticeable that, in the US incident recently, the Navy contributed a Royal Fleet Auxiliary manned by merchant seamen rather than a warship, presumably because we did not have one available. Meanwhile, the Ministry of Defence is arguing about which capabilities should be cut so that we can live within the wholly inadequate defence budget. When will the Government more widely start acting as though they believe the warnings that they rightly continue to issue about the perils of the international situation that we face?

[Lord Coaker (Lab)]

The noble and gallant Lord will know that we await the defence investment plan, which will lay out the capabilities that the Government believe that we need for war-fighting readiness. The noble and gallant Lord will also know that we have taken action in the Baltic to protect underwater critical infrastructure, with “Proteus” and other capabilities. He will also know that, with respect to the interdiction of the shadow vessel between Iceland and Scotland, we used RAF surveillance aircraft and reconnaissance aircraft, as well as the RFA ship. It is also worth pointing out that, notwithstanding the might of the United States, it asked for our support and help in doing what it did, and we were happy to give it.

Defence Spending

Lord Stirrup Excerpts

Tuesday 6th January 2026 Lords Chamber

[Lord Coaker (Lab)]

The noble Baroness will first have to tell me how long an elephant’s pregnancy is— I have absolutely no idea whether that is good news or bad news, and I do not know whether anybody else does.

The noble Baroness makes a serious point, challenging the Government on the defence investment plan. I say to this House and to the noble Baroness, who I know takes a keen interest and is very supportive of defence overall, that the defence investment plan will be published when we are in a position to have made the necessary choices to deliver the war-fighting readiness that we want and the capability to fight if we need to, now, in the middle term and in the long term. There are in-year choices that we are dealing with, and the chiefs are fully involved in the discussion and debate on how we take that forward.

[Lord Stirrup (CB)]

My Lords, the noble Lord, Lord Livermore, who I am pleased to see has just taken his place, said in answer to a previous Question in this House that any increase in the defence budget beyond 2.5% is a matter for the next Parliament and anything beyond 3% is a matter for the Parliament beyond that. Does the Minister realise that this is a wholly irresponsible attitude? If we are to achieve 3.5% of GDP on defence by 2035 in a sensible, graduated manner that expands the defence industrial base in this country at a sensible pace, along with military capability, we need a plan for doing it now, and it needs to start today, not in 2030.

Nuclear Non-Proliferation Treaty Review Conference 2026

Lord Stirrup Excerpts

Wednesday 10th December 2025 Lords Chamber

[Lord Coaker (Lab)]

I strongly agree with the noble Lord’s analysis. The NPT is an essential cornerstone of global security. I suggest that in many ways it has been particularly successful. I was looking at the figures earlier on. In 1986, there were an estimated 70,300 nuclear warheads, according to the Stockholm International Peace Research Institute, and the most recent figure I could find was 12,241. Although there are challenges, as the noble Lord points out, we have managed in many ways to control the proliferation of nuclear weapons and to ensure that, as far as possible, the architecture of the post-war world remains the same. However, the noble Lord is right to point out the challenges, and this country, along with our allies and friends, will do all we can to ensure that the NPT remains successful and that all three pillars are pursued.

[Lord Stirrup (CB)]

I endorse the Minister’s comments about the tragic loss of Lance Corporal Hooley and express sympathy to the lance corporal’s family and friends. What analysis have the Government made of the likely impact on non-proliferation efforts of the wholly inadequate response of the international community to Russia’s violation of the Budapest memorandum through its annexation of Crimea in 2014 and its subsequent war of aggression in Ukraine?

[Lord Coaker (Lab)]

I thank the noble and gallant Lord for his comments, and I should have thanked the noble Baroness for associating herself with the remarks that I made about the tragic death of our serviceman. The lesson I think we should learn as a country is that it is important for us to reassert and re-establish the principle of deterrence. Part of preventing war is actually preparing for war. The whole success of the deterrent is the fact that the nuclear deterrent is there—the theory of deterrence. I think what happened following the Budapest arrangements, the withdrawal of nuclear weapons there, is perhaps a lesson for us that sometimes a position of strength allows you to negotiate and pursue peace more effectively than in the alternative way.

Strategic Defence Review 2025

Lord Stirrup Excerpts

Monday 8th December 2025 Lords Chamber

[Lord Coaker (Lab)]

The noble Lord is absolutely right: it is an important matter and a radical proposal, and it is to do with the new threats we face as a country. We cannot any longer simply carry on as we always have done, so the proposals in this strategic defence review are radical and serious, and we intend to deliver them. One way that we intend to do that is to start to talk to the population of this country about the need for us all to wake up to the threat we face. That will require many of the actions that the noble Lord pointed out, and we intend to come forward with proposals in due course.

[Lord Stirrup (CB)]

My Lords, recent surveys suggest that there is weak to no openness among Generation Z to engage with defence or security issues. Going further on what the Minister has just said about talking to people, does he agree that any whole-of-society approach to defence must, as a precursor, require the Ministry of Defence and the Armed Forces more widely to reconnect with societal attitudes in this country, particularly among young people? If he does agree, can he say in more detail how the Government intend to go about this?

[Lord Coaker (Lab)]

I agree very much with the noble and gallant Lord’s points. As he said, the reconnection between the military and the civilian population is crucial. The one positive thing I would say is that, just a few weeks ago, like many noble Lords, I was at the remembrance events, where up and down the country tens of thousands of young people were remembering the sacrifice made in the past. They were Scouts, Guides, cadets and Reserve Forces—all of those. That is not a solution to the problem, but it points the way forward. It is one thing we should celebrate, as well as looking at the challenges we still face. The noble and gallant Lord will also know that we look to extend and expand the reserve and cadet forces. That will take some doing, but we are determined to do it.
