Cabinet Office

Debate between Matt Western and Helen Maguire

Monday 29th June 2026 Commons Chamber

[Matt Western (Warwick and Leamington) (Lab)]

I thank the Backbench Business Committee for granting this debate, which could not be more timely given the crucial NATO summit next week in Ankara. I was hoping that we would be inundated with contributions from across the House, but sadly it looks as though we might be limited to one or two.

Keeping the country safe is the first responsibility of any Government. The Joint Committee on the National Security Strategy, which I chair, has undertaken a huge amount of work during this Parliament to examine the Government’s approach to protecting the UK’s national security interests. From critical national infrastructure to the defence of our very democracy, our Committee has been working hard to highlight areas in need of vital improvement.

There is no one “National Security Department”, of course, but the Cabinet Office co-ordinates the Government’s approach to national security and is the home of the national security secretariat. The Cabinet Office’s main estimate states that it plans to spend about £1.1 billion on day-to-day running costs and £600 million on investment projects, of which around £200 million in day-to-day costs and £25 million in investment will go towards keeping the country safe. However, national security is, at its core, a whole-of-Government responsibility, and it is therefore often difficult to get a handle on how much is being spent on the UK’s security and resilience—a point that I made to the Backbench Business Committee.

In an era of unprecedented uncertainty and hybrid warfare, the case for increased spending on security and resilience could not be stronger. We see a proliferation of threats not just from hostile state actors, but from organised proxy groups and radicalised individuals. Take the cyber-attack on Jaguar Land Rover in August 2025. The New York Times now reports that it was Russian in origin, and the evidence suggests that the Kremlin was either directly responsible for it or responsible for facilitating it through proxy actors. The impact was severe: it cost the British economy £2.5 billion, directly cost Jaguar Land Rover £485 million in the quarter and affected more than 5,000 firms. It was so significant that it impacted our quarterly growth figures.

Threats are increasingly facilitated through the weaponisation of emerging technologies, such as artificial intelligence and quantum. Those who would seek to destabilise our democracy, our safety and our way of life have more opportunities than ever before to do so, and they know that. Meanwhile, the Government and NATO allies have already acknowledged this reality with their commitment to spend 5% of GDP on defence by 2035, with 1.5% of that being earmarked for security and resilience.

[Helen Maguire (Epsom and Ewell) (LD)]

Does the hon. Member believe, like I do, that the Russian hybrid warfare we are seeing in the UK at the moment is further fuelling disinformation, including online? We know that the arson attack on the Prime Minister’s car was directly linked to Russian state operatives. If there was ever a moment when we needed to stipulate a specific budget, now is that moment.

[Matt Western]

That is such an important point, and I do not think that we as a Chamber have given it enough airtime. If we think about what would happen if any other premier of any other country was attacked like that—their home attacked and their car set on fire—the reaction from the media was quite muted. Now that it has become more obvious what happened, despite all the nonsense that circulated on social media at the time, it is important that that conversation happens.

We are at a crucial juncture, as the hon. Member suggested. We are running out of time to ensure that we are prepared for a worst-case scenario of increasing Russian aggression, both conventional and hybrid. At a time when the United States’ security presence in Europe is being questioned, the threat from China looms ever larger, and the UK finds itself in a difficult position as a middle power in the midst of global strategic competition between the United States and China. As such, it is imperative that the Government are robustly held to account in delivering their spending commitments on defence, security and resilience.

[Matt Western]

My hon. Friend is absolutely right. I have not been to Canada in recent decades, but I am hearing that its approach should be of real interest to us, including how it is prioritising certain sectors and has identified certain capabilities. Although people are protective about what those capabilities might be, I would certainly welcome conversations behind closed doors with Ministers about what we are looking to do in a similar vein.

It is striking that the Canadians are outlining their major projects and how they will spend their money, but they are also focusing on their capabilities. Here we have suffered from a lack of long-term commitment to investing in national security and preparedness. Our Government must also clearly outline what additional capabilities they are committed to developing through the target spend, prior to the start of the NATO summit next week. We need a national conversation about our nation’s defence and security. Over the last 18 months my Committee has heard repeatedly about the need to get the public on board when it comes to increased spending on defence, resilience and security. With the public purse under such strain, our constituents must understand why spending on such areas must be prioritised.

[Helen Maguire]

I also recently met the ambassador to Canada—this goes back to the point raised by the hon. Member for Stafford (Leigh Ingham), who stated that one reason for the infrastructure in the High North was so that there was something sovereign to defend. That is incredibly important. The ambassador also explained how, when selling that to the general public, when most people talk about defence they think about different toys—bullets and ships—whereas in Canada was talking more about investing so that they have something to defend that is about their country, jobs, industry and everything else. Does the hon. Member agree that we should also get that important message out to UK residents?

[Matt Western]

As if on cue, the hon. Member’s point is one I am just about to develop. The strategic defence review called for a national conversation, and during our inquiry on societal resilience we heard much about how our allies are engaging their citizens with that essential work. The UK is, I am afraid, a little behind the curve. Beyond the Baltic and Scandinavian nations, whose security and resilience is well documented, other nations are also moving up a gear. Their Governments engage significant numbers of military reserves, volunteers, firefighters, private defence organisations and NGOs in that conversation. In certain countries, everyone between the ages of 18 and 65 has a role in resilience—every single person. Some countries conduct wargame exercises on civilian defence, to identify weaknesses in their systems. Less obvious countries such as the Netherlands and Canada are making painful choices that are necessary to ensure that societal resilience can be strengthened. The situation warrants a reset of our whole approach to resilience and security, but to do that we must bring the public with us through a national conversation.
