France Proposes Ceiling on UK Role in €150bn EU Defence Fund

Published: 16 September 2025. The English Chronicle Desk

France has moved to impose limits on the use of British-made military components in the European Union’s €150bn defence fund, a decision that could complicate the United Kingdom’s hopes of playing a greater role in the bloc’s growing security and defence programmes.

According to diplomatic sources, French officials suggested that a maximum of 50 per cent of the value of any Safe-funded project should be made up of UK components. The Security Action for Europe (Safe) initiative, worth €150bn in loans, is central to the EU’s ambitious plan to raise defence spending by €800bn and strengthen its military readiness in response to mounting global threats. The proposal, raised during internal discussions in Brussels, is viewed by several diplomats as a clear attempt by Paris to reinforce its long-standing vision of a European defence industry less dependent on outside powers, including Britain.

The push comes despite the signing of a defence and security partnership earlier this year between Prime Minister Keir Starmer and European Commission President Ursula von der Leyen. That agreement was heralded as a breakthrough in repairing post-Brexit relations, allowing the UK to contribute more substantially to EU defence projects by lifting a previous restriction that capped non-member state contributions at 35 per cent. The new proposal from France, however, risks diluting the impact of that deal.

French officials have insisted that the scheme must prioritise Europe’s own defence manufacturers and argued that safeguarding the EU’s industrial base is a matter of strategic necessity. A spokesperson from France’s permanent representation in Brussels said the Safe regulation already outlined the principle that significant proportions of any funded project must be sourced from EU industries, and that Paris was only seeking to ensure these rules were followed in practice.

Yet the idea of a cap has not been warmly received across the bloc. A majority of member states, including some of the largest beneficiaries of the Safe loans, are said to oppose restrictions on UK participation. They argue that the British defence sector remains one of the most advanced in Europe and that limiting its role would be counterproductive, particularly at a time when Europe is under pressure to supply both its own forces and those of Ukraine. One EU diplomat described the French proposal as “a classic obsession”, noting that most governments favoured greater flexibility in sourcing military equipment.

The Safe fund is not designed to provide loans to the UK, as non-member states are excluded from direct borrowing. However, the UK hopes its defence firms will benefit from contracts and supply-chain involvement, ranging from the production of drones and artillery systems to the provision of ammunition and precision weapons. To secure this participation, Britain must negotiate not only technical terms but also a fee covering administrative costs associated with joining the scheme. Talks on these issues are expected to take place in the coming weeks, though the EU first needs unanimity among member states on its negotiating position.

The debate reflects a wider tension within the EU over how far to open its defence market to close allies outside the bloc. France, long a proponent of European strategic autonomy, has consistently pressed for stricter barriers, arguing that Brexit placed the UK outside the rules and benefits of the single market. Other member states, by contrast, see the UK’s inclusion as critical to Europe’s ability to deliver on its defence commitments.

The European Commission has so far sought to play down the divisions, with its spokesperson on defence, Thomas Regnier, emphasising that the UK remains an essential ally. “The UK is an essential partner and ally for the EU, with whom the president has signed a security and defence partnership in May. They have a very advanced defence industry, we share many common interests, hence our will to sign a win-win agreement to fully associate them to our Safe instrument,” he said.

The stakes are high. Last week the Commission confirmed that 19 member states had already signed up for loans under the Safe programme. Poland secured the largest share with €43.7bn, nearly a third of the total, while France and Hungary borrowed €16.2bn each, Romania €16.7bn and Italy €14.9bn. These loans, backed by the EU, lower borrowing costs for governments and can be spent on strengthening national armies or supporting Ukraine’s war effort.

For the UK, the outcome of the negotiations will determine whether it can capitalise on a rare moment of alignment with Brussels under Keir Starmer’s government. For the EU, the debate will test whether its drive for greater defence autonomy can be reconciled with the practical benefits of keeping Britain engaged in Europe’s security framework.

As one senior European diplomat put it, the question at stake is not merely about the percentage of British components in a weapons system, but about the future shape of Europe’s defence identity and whether one of its closest allies will be allowed to play a full role in it.
