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.
