The United Kingdom faces a materially higher and more persistent level of geopolitical risk than at any point since the end of the Cold War. Sustained conflict in Europe, cyber and hybrid threats, pressure on defence supply chains, and increased alliance expectations all point to the need for greater defence resilience and surge capacity.

Defence remains a core, non-delegable responsibility of the state and must continue to be funded through general taxation, subject to parliamentary approval and scrutiny. This petition does not propose any reduction, substitution, or offset to existing or future tax-funded defence budgets.

Instead, it recommends that the Government formally consider the creation of a voluntary, uncapped, ring-fenced Defence Resilience Fund, operating strictly in addition to the core defence budget.

Proposed design principles

Any such fund should be established only if it meets the following conditions:

• Voluntary participation only, with no expectation, obligation, or linkage to citizenship, services, or influence
• Legal ring-fencing, restricting use exclusively to defence and national security purposes
• Non-substitution guarantees, explicitly preventing the Treasury from reducing baseline defence spending in response to fund balances
• Parliamentary oversight, including defined authorisation thresholds for deployment
• Independent audit and transparency, with regular public reporting
• No donor influence, earmarking, or policy direction rights

The fund would function as a strategic reserve or resilience buffer, not as a mechanism for routine operational funding or annual budget planning.

Rationale

A voluntary defence top-up mechanism could, if properly governed:

• Provide additional contingency capacity outside annual budget cycles
• Improve national resilience to supply-chain shocks and rapid escalation scenarios
• Allow citizens who wish to do so to contribute financially in a transparent, structured manner
• Strengthen deterrence signalling without immediate tax increases or public borrowing
• Complement, rather than complicate, existing fiscal and defence planning frameworks

The UK has historical precedent for citizen participation in defence financing (e.g. war bonds), as well as modern precedent for voluntary, hypothecated public funding in other domains. What is proposed here is a contemporary, tightly governed adaptation—appropriate to peacetime democratic norms.

What this proposal explicitly avoids

• It does not privatise defence responsibility
• It does not replace democratic decision-making on the use of force
• It does not create parallel command, procurement, or policy structures
• It does not rely on public sentiment for core defence readiness

The request

We call on the UK Government to:

• Commission an independent review into the feasibility, governance, and risks of a voluntary Defence Resilience Fund
• Set out the legal and fiscal safeguards required to prevent budget substitution or politicisation
• Engage Parliament on appropriate oversight, deployment triggers, and transparency standards
• Publish a clear assessment of whether such a mechanism would enhance deterrence and resilience without undermining fiscal discipline or democratic accountability

This is a question of institutional design, not ideology. Given the strategic environment, it merits serious, evidence-based consideration.
