Defence

Iain Duncan Smith Excerpts

Tuesday 24th March 2026 Commons Chamber

[Al Carns]

Defence is very clear about what it requires. We are working collectively across Government to come to a joint decision on where that spending portfolio will fall.

There are points in this motion that are obvious. The world is more dangerous, and we are investing more in defence, but recognising that is the easy part; the real question is whether we are prepared to make the decisions required to deal with it. Defence is not a shopping list, and it must not be treated as such. It is not about picking a number of troops, as mentioned in the motion, and it is not about shifting money around on paper. It is about building a force that works—one that is properly equipped with the correct equipment, properly supported and able to operate alongside our allies. In my time in uniform and since coming into this role, I have spent time in multiple different operational theatres, and I know that this is not about the size of the armed forces; it is about the plan. This is about the purpose, the equipment and how people will be integrated. Simply stating that we should add 20,000 extra troops to the Army, with no clear or concise understanding of how they will be used, is not the way to go about business.

[Sir Iain Duncan Smith (Chingford and Woodford Green) (Con)]

The Minister is making a powerful case. A man with his record and history coming to this place is to be congratulated, and I am enthused to see him in his place today, as I think we all are.

We have talked about the non-appearance of the defence investment plan, but there is another review that has not appeared that has even more impact: the review on China and the threat that it poses to us. That was promised again by the Government. I raise this issue because under Conservative and Labour Governments, I have gone on constantly about the growing threat, and we have not faced up to it. China is critical to this matter; if we watch the tankers going into the strait of Hormuz and out again without any problems, we begin to realise the incredible links that China has with Iran, Russia and North Korea. Is the Ministry of Defence demanding that that review is handed to it and published, or has it forgotten about it?

[Al Carns]

I thank the right hon. Member for a very balanced contribution, as always. On the specific issue, I will come back to you and write to you on where we are and how the review is moving forward.

I will continue and then give way in a minute.

We have taken more action in the past 20 months than the Conservatives managed in the 14 years before that, with more than 1,200 major defence contracts, 86% of which have been awarded to British-based businesses. The Conservatives argued that we should spend 2.5% of GDP on defence by 2030; we are delivering it by 2027.

[Al Carns]

I will give way to the right hon. Gentleman.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

Order. Let me just say to the Minister: no more “yous”.

[Sir Iain Duncan Smith]

I sense that this little fracas is something of a tautological tap dance. We are at war, and I do not think Iran cares whether we made the strike on it or not, because it still sees us as a target. We accept that, and that is the danger that our troops are in.

However, I want to ask the Minister about something else. I want to ask again the question that I asked the Defence Secretary yesterday. Is it not the reality that we are at war, and that Iran is an enemy of ours and has been for a considerable time? It has been carrying out operations here. It has been stirring up Islamic extremism, and we are seeing targeted antisemitism and hate marches. That is all part of Iran’s plan. Is it not time that the Government finally said “Enough is enough”, proscribed the Islamic Revolutionary Guard Corps and arrested the hell out of these people who are causing mayhem on our streets?

[Al Carns]

I thank the right hon. Member for his comments. I will raise them with the Security Minister, and push exceptionally hard.

The motion suggests that we are failing to learn lessons from Ukraine. Let me make it absolutely clear that these are two separate issues. This Government are leading. We committed £4.5 billion in military support last year, building on £3 billion annually. We have co-led the Ukraine Defence Contact Group, which has helped to secure over $45 billion of investment, and in February alone a further $35 billion was raised. However, we have not just provided funds; we have adapted.

At this point, I want to recall my own history. I left the military in 2024. I left because the Government and the military collectively were not learning the lessons from Ukraine. That is the very reason I left to come to this place. Labour was not in government at the time, and we were already years into the conflict. Opposition Members will recognise this as being one of my hobby horses since I have been in the Ministry of Defence.

There has been a tenfold increase in drone delivery, with a target of 100,000 this year. A new cyber and electromagnetic force has been built on lessons from the battlefield in Ukraine, and £4 billion has been committed to autonomous systems over time. We have seen Project Asgard, a hybrid Navy, a defence uncrewed centre of excellence in the SDR, a cultural change within the Army, Navy and Air Force in respect of uncrewed systems, an increase in uncrewed systems training, and cultural development in phase 1 and phase 2 training. I am therefore confused as to how no lessons are being learned. We must go faster, and we are pushing as hard as we can, but I want to be very clear about this, and I will bring you back to the first point. I left the military because your Government—[Interruption.] I left the military because the Conservative Government were not learning the lessons effectively from Ukraine.

Let me turn to the topic of Northern Ireland and morale. I do not recognise the argument advanced in the motion.

[Sir Iain Duncan Smith]

Will the Minister give way?

[Al Carns]

I am going to a make a bit of ground, and then I will come back to the right hon. Gentleman.

We come to perhaps the most revealing part of the motion: the suggestion that defence should be funded through changes to the two-child benefit cap. Let me say this plainly: you do not strengthen national security by setting it against support for working families, you do not ask the country to choose between security abroad and stability at home, and you do not build credible defence policy on that basis. It is the job of the Government to make life easier for families, not harder.

I will say something else. I grew up in a family where decisions about money took place, and I see the same pressures on the communities that I now represent. Security is not just about what happens overseas; it is about whether families feel that they can cope, whether they feel stable and whether they feel that the system is working for them. The Conservatives’ motion is not a serious way to approach defence funding, because the strength of a country rests both on armed forces that can deter and defend, and on a society at home that is stable, resilient and confident. Pitting one against the other does not strengthen either; it weakens both.

This Government are taking a different approach. We are making decisions in the national interest, and we will not be pushed into those decisions by noise or pressure—we will take them carefully and responsibly. We are increasing defence spending, strengthening our forces—whether it be recruitment or outflow, or the morale component as a whole—and ensuring that our forces are ready to face threats both now and in the future. We will publish our defence investment plan, but we will not rush it for the sake of a headline. As has been demonstrated over the past 14 years, a plan that is not properly funded or deliverable does not strengthen our security, but weakens it.
