Conclusions (16)
1
Conclusion
Accepted in Part
The Government must balance transparency with the public about the reality of threats the UK faces with not causing alarm and making sensitive information unnecessarily accessible to adversaries. However, there is a sense among industry stakeholders and civil society organisations that they were not sufficiently consulted in the development of …
Government Response Summary
The government agrees on the importance of public awareness and engagement, detailing efforts for transparency through stakeholder consultation, an update on the China Audit, and a "transparent by default" approach for the NSRA. They also commit to publishing annual public survey findings on risk perception and continuing annual statements to Parliament on resilience.
4
Conclusion
Acknowledged
Soft power is a crucial source of UK influence and security abroad. Its erosion would have direct security consequences, most clearly in Africa, where Russia and China are increasingly filling the space left by the withdrawal of the soft power presence of the UK and allies. Official Development Assistance and …
Government Response Summary
The government agreed on the vital role of soft power and described its ongoing efforts, including the establishment of the UK Soft Power Council and a refined ODA approach focused on stability and conflict prevention, while ensuring stable grant funding for key institutions.
6
Conclusion
Acknowledged
The lack of clarity over which departments are responsible for which areas of national security policy hampers the possibility for external scrutiny and challenge of national security policy delivery. Our opinion was further solidified when the Department for Science, Innovation and Technology declined to put forward a minister to give …
Government Response Summary
The government described its internal approach for accountability, assigning lead departments and offering to update the committee on progress. It supported the principle of ministerial accountability but reserved the right to determine which minister is best placed to attend.
9
Conclusion
Accepted
Hitting the target to spend 1.5% of GDP on resilience and security by 2027 will be a limited achievement if it does not create any additional resilience capability for the UK beyond what was already allocated in the 2025 Spending Review. We appreciate that the 1.5% target is still new, …
Government Response Summary
The government explains that NATO has agreed on the definition of the 1.5% spending target for resilience and security, addressing the lack of clarity. They expect to meet the target by 2027 and will report spending lines to NATO shortly.
11
Conclusion
Accepted
We welcome the greater use of Armed Forces Reserves in protecting Critical National Infrastructure (CNI), but necessary detail on these plans is lacking. Private sector organisations with responsibility for the protection of CNI also need a clearer steer on what they will be expected to do to bolster resilience of …
Government Response Summary
The government accepts the need for clarity, committing to mapping resilience standards and developing guidance for CNI owners and operators. It also mentions amending the Reserve Forces Act and an upcoming National Cyber Action Plan to strengthen resilience, including for CNI.
14
Conclusion
Accepted
While we welcome ambitions to scrutinise resilience plans through the UK Resilience Academy, it is unclear at this stage how effective its scrutiny will be. How far its scrutiny remit will stretch, and whether this will include reviewing preparedness plans in the event of a crisis or warfighting situation, and/or …
Government Response Summary
The government addresses the committee's questions about the UK Resilience Academy's effectiveness and remit by stating it is being instructed to convene expert panels annually to scrutinise preparedness for whole-system civil emergencies and is developing a national exercising hub linked to risk monitoring.
17
Conclusion
Accepted
The Government has identified the need for a whole-of-society approach to security and resilience through a national conversation, but it is not evident that this message is getting through to the public. There is a long way to go to realise the whole-of-society approach to defence and security. (Conclusion, Paragraph …
Government Response Summary
The government acknowledges that the national conversation on security and resilience is a government-wide effort already underway, citing high-level speeches and ongoing public surveys. It confirms commitments made in the Resilience Action Plan and Strategic Defence Review and will publish updated information in due course.
19
Conclusion
Acknowledged
Global and UK security is poorly served by the increasing tensions brought about by great power competition between the United States and China. If this process continues to accelerate, the economic shock costs of military confrontation will go down, making conflict more likely. The post-war security settlement has served the …
Government Response Summary
The government agrees with the committee's conclusion that global security is challenged by increasing tensions, stating that it aligns with the National Security Strategy's acknowledgement of radical uncertainty and the need for statecraft to adapt.
21
Conclusion
Acknowledged
The Government has identified Russia as the primary threat to the UK’s national security and continues to do good work to deter further Russian aggression. The Committee commends the Government for its continued military and financial assistance for Ukraine and its planned investment in sharpening the UK’s hard power, including …
Government Response Summary
The government welcomes the committee's support for its work against the Russian threat and in aiding Ukraine. It reaffirms its commitment to working with NATO allies, taking a leadership role in European security, and mentions forthcoming plans like the Defence Investment Plan and Defence Readiness Bill.
23
Conclusion
Acknowledged
China poses a clear long-term national security threat to the UK—both directly through its malicious targeting of UK interests, and indirectly through its support to Russia over the Ukraine conflict. We have concerns that the Government is not striking the right balance—and indeed about whether it is prepared to accept …
Government Response Summary
The government acknowledges China's long-term national security threat and states it is taking a strategic approach that balances economic engagement with robust challenge, citing existing measures like the NSI Act and ongoing diplomatic engagement with China regarding Russia.
25
Conclusion
Accepted
The UK has strategic dependencies on the United States for core capabilities in nuclear, intelligence and conventional defence. While it is positive that the Government has recognised the need for the UK to prepare for a future where the United States makes a less active contribution to European 65 security, …
Government Response Summary
The government affirmed its commitment to interdependence and burden-sharing within NATO, detailing existing collaborations with European partners and new investments in sovereign capabilities to strengthen Euro-Atlantic security and reduce overdependence on any single state.
28
Conclusion
Acknowledged
We welcome the Government’s efforts to diversify partnerships, illustrated by deepening trade and security collaboration with India and engagements with Gulf countries. This work is crucial both to ensuring the UK can draw on breadth and depth in its partnerships to support economic growth, and improve resilience during periods of …
Government Response Summary
The government agrees on the importance of pursuing strategic relationships and highlights its ongoing efforts, including new partnerships with Japan, Indonesia, and India, and the use of instruments like the National Security and Investment Act.
30
Conclusion
Acknowledged
A credible, sustainable and independent UK nuclear deterrent is integral to UK national security, and as a buffer against allied proliferation in an era of fast-changing nuclear risks. (Conclusion, Paragraph 135)
Government Response Summary
The government agrees with the conclusion, highlighting existing measures such as the NSS and SDR outlining the threat, £6bn investment in nuclear submarine facilities, and deepened nuclear cooperation with France.
32
Conclusion
Rejected
The National Security Strategy is clear that sovereignty over certain national security capabilities, including nuclear, emerging technologies, shipbuilding and steelmaking, is important. However, beyond this, there is no clear definition of how the Government defines what it considers to be a sovereign capability. Nor is there sufficient indication of what …
Government Response Summary
The government rejects providing a strict definition or published list of sovereign capabilities, citing risks. It states clarity is instead provided through existing strategic frameworks like the Industrial Strategy and the National Security and Investment Act, with further details coming in the Defence Investment Plan.
33
Conclusion
Acknowledged
We appreciate that the definition of sovereignty will differ by sector and by degree. However, the general lack of clarity on definitions and objectives complicates research and development planning and investment. The UK has a strong base of talent and skills in emerging technologies— artificial intelligence in particular—where some level …
Government Response Summary
The government acknowledges the need for clarity but states they will not provide a strict definition of sovereignty, opting instead for a flexible approach through strategic frameworks like the Industrial Strategy and National Security and Investment Act. They believe these existing mechanisms, alongside the forthcoming DIP, provide sufficient certainty and signalling for industry.
36
Conclusion
Deferred
Industry lacks an adequate signal from Government on the allocation of spending across the defence, security and resilience sectors. This impacts the ability to plan research and development spending in a way that aligns with Government objectives, and prioritises the most important sovereign technologies. For SMEs in particular, this contributes …
Government Response Summary
The government commits to addressing the issue of inadequate signals by publishing a forthcoming Defence Finance and Investment Strategy and an SME action plan with a direct spending target, once the Defence Investment Plan is finalised.
