Defence

Meg Hillier Excerpts

Tuesday 24th March 2026 Commons Chamber

[James Cartlidge (South Suffolk) (Con)]

I beg to move,

That this House regrets that the Defence Investment Plan has still not been published despite the Government promising Parliament that the plan would be published in Autumn 2025; notes that the Government’s delay has frozen procurement and has stopped the UK from learning lessons from its long-standing support for Ukraine and left the UK vulnerable as the world becomes more dangerous; believes that the Northern Ireland Troubles Bill and the Northern Ireland Troubles (Legacy and Reconciliation) Act 2023 (Remedial) Order 2025 should not be proceeded with because they are a threat to morale, and that the Diego Garcia Treaty should not be ratified to ensure that the UK continues to have sovereignty over its military base; calls on the Government to publish the Defence Investment Plan as soon as possible; and further calls on the Government to increase spending on the UK’s armed forces, specifically delivering 20,000 more troops over the next Parliament, paid for by restoring the two-child benefit cap, and redirecting net zero funding to defence, to ensure that the UK spends three per cent of GDP on defence by the end of this Parliament.

It is a pleasure to open this Opposition day debate. I join the Liaison Committee, the Public Accounts Committee and the Defence Committee in asking the Government one simple question: when on earth will they publish the defence investment plan? Yesterday, the Prime Minister was unable to answer that simple question. It means that, at a time of war and conflict on multiple fronts, and amid the most dangerous time for our country since the cold war, instead of delivering rapid rearmament, Labour is presiding over a procurement freeze. Perhaps that should come as no surprise, given the Prime Minister’s constant habit of dither and delay.

Since 28 February, when the US and Israel started their campaign against Iran, the Conservative position has been that, had we been in government and the US had asked to use our bases, we would have granted permission. In contrast, the Prime Minister has not only dithered and delayed over sending the Royal Navy to the middle east, but constantly U-turned on whether to allow the US to use our bases. That is weak leadership when we need to stand strong in this dangerous world. Now, we are seeing the consequences of the Prime Minister’s weakness on the home front. As war wages around us, he is unable even to confirm whether the defence investment plan will be delivered this week. I urge the Minister to tell us at the outset of his remarks, but before he does, let us remind ourselves of what Labour Ministers have said before.

On coming into office, the Defence Secretary made a choice. He chose not to implement the munitions plan I had produced, which detailed comprehensively how we could rapidly replenish the vast amount of shells and missiles that we had given to Ukraine. Instead, he decided to launch a strategic defence review that would boil the ocean. In multiple written questions, we asked what Labour would do on specific capability, and the answer was always the same: “Wait for the SDR.” So we waited and waited—it was promised for the spring of 2025, and was delivered in the summer—but the SDR did not have any of the specific procurement choices that our entire defence industry is waiting for. After all the hype about the SDR, those decisions were punted into yet another review: the defence investment plan.

In June last year, the Secretary of State promised from the Dispatch Box that

“the work on a new defence investment plan will be completed and published in the autumn.”—[Official Report, 2 June 2025; Vol. 768, c. 72.]

But summer turned to autumn, autumn turned to winter, and still there is no DIP.

rose—

[James Cartlidge]

Maybe the hon. Lady knows when we will get it; I give way.

[Dame Meg Hillier]

I have to say, the hon. Gentleman has some chutzpah, given that one of his Government’s many defence reviews had more pictures than pages. I agree with him that we should be serious-minded on this matter—we need to be prepared for defence—but under his Government, projects were delayed and aircraft carriers were without aircraft, and the ongoing Ajax saga is still be resolved. He needs to take responsibility, too. Across the House, we all want to ensure that we are ready to defend our nation.

[James Cartlidge]

There was no question in that intervention, but I am glad that the hon. Lady agrees that the Government need to get on and deliver the defence investment plan. To be fair, MPs from across the House have said so, including the Chair of the Defence Committee. We all know that it is in the national interest for the DIP to be published.

After all, the defence investment plan being delayed has consequences, the most serious of which are for our military personnel, who we want to have the best equipment for their job. In taking the decision to pause urgent procurement and instead boil the ocean, the Defence Secretary walked into a Treasury trap. Procurement has been on hold ever since, and the Ministry of Defence has been forced to focus on in-year savings, including £2.6 billion for this year alone. Such penny-pinching explains why, until HMS Dragon finally arrived on the scene, we had no warships in the middle east for the first time in decades.

One of the most critical consequences of the delay to DIP is the Sea Viper Evolution procurement. The fact that a US destroyer intercepted at least one of the missiles that Iran fired at our sovereign territory on Diego Garcia underlines how important it is that our Type 45s are able defend against the most advanced threats. For the UK, that requires the Sea Viper Evolution upgrade for our Type 45 destroyers.

In my own SDR submission as shadow Defence Secretary, through numerous speeches in the House and in many written questions, I have repeatedly urged the Government to accelerate Sea Viper Evolution as a priority for our munitions plan. I am sure that members of the public who are watching this debate, worried about Iran’s attack on Diego Garcia, would expect such a capability to have been ordered as rapidly as possible. However, in a written answer this January, when I was once again chasing this critical upgrade, I received the inevitable response that continued progress on Sea Viper Evolution remains

“subject to the defence investment plan.”

That is the problem in a nutshell—the impact of Labour’s procurement freeze in real time. The reality is that Sea Viper Evolution is not due to reach full operating capability until late 2032.

[Al Carns]

We will publish the defence investment plan as soon as is feasible. The hon. Gentleman will not find anyone who wants more than me more defence spending at a faster rate, but this is a moment for serious decisions to be taken in the national interest. We need to get ourselves back on track. There has been a whole plethora of funding decisions over the last 14 years, which I lived through, and I am sure some hon. and gallant Members present lived through, that in the current environment are no longer fit for purpose.

[Dame Meg Hillier]

I am sure my hon. Friend will remember that at one point when he was serving our country the last Government put an extra £4.5 billion into defence spending. However, time after time, every witness that came in front of the Public Accounts Committee told us how it was not solving their funding problem and was overspent many times. Does my hon. Friend agree that we need rigour in spending that actually delivers the kit to our men and women on the ground, in the air and at sea who are serving our country?

[Al Carns]

I thank my hon. Friend for her contribution. We have a large defence budget, and in the past it has not been spent effectively.

I think we can collectively agree, on both sides of the House, that huge procurement mistakes have been made in the past that have resulted in either the wrong equipment or the money going the wrong way. We therefore need to take our time to get this right. As Conservative Members will know, the other reason we need to take our time to get this right is that conflict is changing; in some cases, it overtakes some of the capability that was ordered years ago.
