A new warning on Britain’s exposure to food, medicine and industrial supply disruption shows that national preparedness is no longer only a civil contingency issue.

Britain’s supply chains are not prepared for a major shock such as war, pandemic disruption or a sustained geopolitical crisis, according to new research that places food, medicines and critical imports at the centre of the national security debate.

The warning, reported on 24 May, comes from research for the National Preparedness Commission, which argues that the UK has not matched the worst-case planning now being pursued by some European states. The report says ministers should take more direct action to reduce exposure to shocks that could interrupt vital supply chains, including food, medicine and industrial materials. The issue is no longer only one of commercial efficiency or emergency planning. It now sits within the wider question of how European states prepare for conflict, coercion and long-duration disruption.

The immediate concern is that Britain has become heavily dependent on highly optimised supply systems that are efficient in normal conditions but vulnerable under pressure. Just-in-time logistics, lean inventories and global sourcing can lower costs, but they leave limited margin when transport routes are disrupted, manufacturing is concentrated overseas or sudden demand outstrips available stock.

The National Preparedness Commission’s warning is particularly acute on medicines. The UK does not maintain a comprehensive strategic list or stockpile of essential medical supplies comparable with the arrangements used by several European countries. The report also points to the limited reserve requirements placed on medicine suppliers, leaving the health system exposed if imports, active pharmaceutical ingredients or distribution networks are interrupted.

This echoes concerns raised earlier this year by Parliament’s committees and specialist health reporting. A Lords committee report described medicine shortages as a national security issue and urged that supply risks should be added to the National Risk Register, alongside preparedness exercises focused on large-scale medicine and active pharmaceutical ingredient failures. The Pharmaceutical Journal reported that the committee also called for a formal list of critical medicines to guide domestic production and stockpiling.

Food resilience presents a similar challenge. Britain relies on complex domestic and international supply networks for food availability, transport, fertiliser, packaging and labour. The Government’s own UK Food Security Report says food security depends not only on production, but also on the stability of the physical, human and economic infrastructure that carries food from producer to consumer.

That infrastructure has already been tested by weather events, transport disruption, energy prices and global market volatility. The National Preparedness Commission’s earlier report, Just in Case, argued for a shift from “just-in-time” to “just-in-case” planning in civil food resilience. Its recommendations included clearer government responsibility, improved emergency planning and a more realistic assessment of how the public would be affected if normal supply conditions were disrupted.

The strategic context has changed because supply-chain disruption is now part of the wider security environment. Russia’s war economy, China’s dominance in key manufacturing sectors, instability affecting shipping routes and uncertainty over US policy all affect how European states think about resilience. Supply chains can be disrupted by conflict, sanctions, cyber attacks, climate shocks, export restrictions or political coercion. A state that cannot secure basic medicines, food inputs or industrial materials is less able to withstand pressure during a prolonged crisis.

The significance lies in the connection between civil resilience and military readiness. Defence planning does not depend only on troops, equipment and weapons. It also depends on fuel, transport, ports, medical systems, communications, industrial capacity and public confidence. If civilian systems are fragile, the state’s ability to support military operations, sustain deterrence or absorb external pressure is weakened.

European governments are already being pushed in this direction by NATO’s renewed focus on resilience. The alliance has long treated civil preparedness as part of collective defence, but Russia’s full-scale war against Ukraine has made the issue more practical. Stockpiles, repair capacity, redundancy, emergency communications and industrial surge capacity now matter alongside conventional force structure.

The UK Government has said supply chains remain resilient and responsive to emerging pressures, according to the 24 May report. That position reflects the reality that Britain has managed recent shocks without systemic breakdown. However, the issue raised by the National Preparedness Commission is not whether current systems function in ordinary periods. It is whether they would remain functional during a severe and sustained crisis.

The policy question is therefore whether resilience should be treated as a cost to be minimised or as a national capability to be built. Strategic stockpiles, domestic production capacity, diversified suppliers and emergency reserves all carry expense. But the alternative is exposure to disruption at precisely the point when public services, defence institutions and private industry would need reliability most.

The warning should not be read as a prediction of imminent shortage. It is a statement about preparedness. Britain, like other European states, is adjusting to a security environment in which economic systems can become targets and dependencies can become vulnerabilities. In that context, supply-chain resilience is no longer a narrow logistics question. It is becoming part of the defence debate.
