We urge the Government to launch a National Defence Reinvestment Programme, beginning with an initial capital investment equivalent to 5% of GDP. We are concerned the UK has become dangerously underprepared after decades of under-investment in defence (the so-called post–Cold War “peace dividend”).

The Programme should include: Immediate strategic investment in building stockpiles and critical infrastructure for homeland defence. Sustained annual defence investment to ensure Britain possesses the forces, industrial base, and technological edge it needs. Rebuild national resilience to prioritise air and missile defence, munitions production, advanced technologies, cyber security, and the protection of critical infrastructure. Strengthen our defence industrial base and review how to support NATO better. Ensure a credible deterrence for the UK.
