Cabinet Office

Julian Lewis Excerpts

Monday 29th June 2026 Commons Chamber

[Alicia Kearns (Rutland and Stamford) (Con)]

This debate is very timely, and I congratulate the hon. Member for Warwick and Leamington (Matt Western) on securing it. In recent months, the Joint Committee on the National Security Strategy has been joined by an ever-growing and increasingly anxious chorus of voices despairing at the Government’s failings on national security. Lord Robertson, who this Government commissioned and asked to lead the strategic defence review, warned in April that Britain’s security was “in peril” due to the “corrosive complacency” that was being shown towards defence. He went so far as to accuse the Treasury of “vandalism”.

Earlier this month, the right hon. Member for Rawmarsh and Conisbrough (John Healey) resigned as Defence Secretary. He was clear that the reason was a defence investment plan—which, it appears, The Times newspaper has also had sight of—that did not give the armed forces “the resources they need”. He was followed out of the door by the Armed Forces Minister, the hon. Member for Birmingham Selly Oak (Al Carns), who said that the Government’s plans were

“neither transformative enough nor sufficiently funded.”

Given that the hon. Member had served in our armed forces, one would have thought that his warning might have been heeded.

[Sir Julian Lewis (New Forest East) (Con)]

Bearing in mind an item that has appeared in the news reports today, does my hon. Friend agree that either the right hon. Gentleman or the hon. and gallant Gentleman to whom she has just referred would be a far more suitable future Secretary-General of NATO than the present Prime Minister, whose lack of proper funding of a defence policy—among other deficiencies—has led him to be looking for a new job?

[The Minister of State, Cabinet Office (Dame Angela Eagle)]

I congratulate my hon. Friend the Member for Warwick and Leamington (Matt Western) on securing the debate. He will, of course, know the importance to this Government of the topics discussed today. Keeping the country safe is the first responsibility of any Government, and as the world changes, the way we uphold that responsibility must change with it. This adaptability is set out in the national security strategy, published last year at the beginning of the NATO summit in The Hague. Alongside it was the commitment to spend 5% of GDP on national security by 2035—3.5% for core defence spending and 1.5% for broader resilience and security spending.

The Majority of the UK’s hard national security capabilities, such as the recently announced 150,000 drones that the Ministry of Defence will supply to Ukraine by the end of the year, are funded and delivered by line departments. The Cabinet Office’s role is ensuring the effective running of government, and co-ordinating cross-cutting policies and operations. More than 90% of the national security and resilience budget for the Cabinet Office is therefore spent on the day-to-day running costs of the National Security Secretariat. That is a vital body that works with Departments to implement the national security strategy. It develops, leads and delivers policy across Government, and aligns, convenes and brokers the collective efforts of our stakeholders and partners on all aspects of national security. It is the nerve centre of our collective cross-Government security response. However, that spending it is not by any means the vast amount that is spent on national security and resilience across Government.

The Cabinet Office does invest in some assets. For example, the National Situation Centre, which is highly regarded internationally, provides situational awareness for crisis response by bringing together data analysis and expertise. The emergency alerts system is one of many public warning and informing capabilities that the UK Government, devolved Governments and category 1 responders have at their disposal. Since its launch, it has become an integral part of keeping the public safe, allowing the quick sharing of lifesaving information, and it is regularly tested to ensure its resilience. The UK Resilience Academy forms an important part of the skills and engagement offer. It was established in April last year to build the skills that are needed across the whole of society to respond to emergencies.

The national security strategy consolidates various reviews and strategies related to national security into a single, coherent framework. It outlines the strategic context, identifies the main challenges we face as a nation in an era of radical uncertainty, and establishes the framework that the UK uses to guide its actions both at home and abroad. It is both a clear-eyed and a hard-edged plan to deal with the breadth of the challenges that we face, setting out a long-term vision for how we will do three crucial things: protect security at home, promote strength abroad, and increase our sovereign and asymmetric capabilities.

The Government have developed an internal implementation approach to ensure the accountability and delivery of the national security strategy, as well as ensuring that we adapt to a volatile geopolitical landscape. That is why our national security is not the remit of one Department or Minister. We have identified specific objectives, and have assigned lead and assisting Departments to deliver them. Departments are responsible for periodic reporting on progress, and taking action to address any deficiencies.

The Government will continue to update the Joint Committee on the National Security Strategy on progress, through formal public sessions and confidential sessions where appropriate. As part of the implementation of the strategy, we continue to make ourselves a harder target for hostile actors who seek to exploit our open, democratic society. That includes bolstering our cyber and economic security defences, which are essential to the fostering of innovation and growth.

Additionally, we are strengthening the defence of our borders and territorial waters.

In April the former Defence Secretary, the right hon. Member for Rawmarsh and Conisbrough (John Healey), exposed covert Russian undersea activity, paying tribute to the readiness of the UK’s armed forces to respond. In May, Baroness Lloyd, the Parliamentary Under-Secretary of State in the Department for Science, Innovation and Technology, outlined DSIT’s plans to present new legislative proposals to modernise and strengthen penalties for malicious activity impacting our undersea infrastructure.

As I am sure events in recent weeks have made clear, our overriding priority is ensuring stability and security in the Euro-Atlantic area, starting with our unwavering support for Ukraine. In total, the UK has committed up to £25 billion for Ukraine: £16 billion in military support, £5.6 billion in non-military support, and £3.5 billion in UK export finance. We continue to go further, renewing and deepening our key alliances, particularly those with the United States and the European Union. All this work is bolstered by new international partnerships, especially in emerging policy areas such as technology—for example, the UK-India technology security initiative and the UK-Japan frontier technology partnership.

It remains the Government’s intention to publish the defence investment plan before the NATO summit, which will take place on 7 July. The plan will set out much of our future strategy when it comes to how we will protect and defend our country. Let me give Members some idea of its focus. We will rebuild our core defence industrial base, focusing on achieving greater resilience in our stockpiles and supporting warfighting readiness.

[Sir Julian Lewis]

I am going to ask the rather obvious question. Given that the plan is to be put forward under the existing Prime Minister, does that mean that if the new Prime Minister wishes to change it, it will be changed, or will the commitment that is to be made to the forthcoming NATO Assembly have to stand as it is?

[Dame Angela Eagle]

As always, the right hon. Gentleman has asked a very important question. I think the key thing to understand is that this work is ongoing, and that there will be co-operation between the current Prime Minister and—I do not want to get ahead of what Labour party members might decide to do—whoever the next Prime Minister will be. I hope that gives the right hon. Gentleman some assurance.

Beyond defence, we will identify, protect and cultivate other sovereign capabilities, such as foundational industries and frontier technologies, that are critical to our industrial base and national competitiveness. I was interested by what my hon. Friend the Member for Warwick and Leamington said in this connection. We are in close contact and collaboration with states such as Canada to learn as much as we can about how they do resilience, although I might gently suggest that the Canadian landmass is slightly different from the UK landmass when it comes to thinking of organising a defence for it, and slightly different approaches will clearly have to be taken, given the geographical realities. However, there is much on which we can co-operate.
