Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what steps his Department is taking to improve the physical security of (a) military sites and (b) other sites of strategic importance including critical national infrastructure.

I refer the hon. Member to the Written Ministerial Statement laid before the House on 27 November.

Defence is taking decisive action to strengthen security across our estate, reversing years of under-investment and focusing our resources on our highest priority sites. We have delivered urgent physical enhancements, introduced advanced surveillance technology such as the Immediate Threat Mitigation Solution, and we are investing in digital transformation to modernise our approach, including MOD adoption of the Critical National Infrastructure Knowledge Base. Enhanced vigilance, updated guidance, and improved reporting have made it easier for personnel and industry partners to report incidents, while successful recruitment campaigns are increasing our policing and guard capacity.

Our multi-layered security approach combines technology, workforce, and physical security to protect our people and assets. The upcoming piloting of Restricted Airspace above strategic sites and significant investment in remotely piloted aerial systems further enhance our ability to deter and respond to threats.

Defence will use all available levers to take swift action wherever and whenever security is threatened and will not hesitate to pursue prosecution where criminality is suspected. Safeguarding the Defence estate remains a key priority, and we will continue to relentlessly pursue improvements to ensure we deliver the highest standards of security and resilience for our estate.
