A recent poll indicates that four in ten supporters of Brexit believe the United Kingdom should strengthen its defence ties with Europe, highlighting a notable shift in public opinion a decade after the EU referendum. The survey, conducted by Savanta between September 4 and 7, reveals that half of all UK voters now prioritise closer security cooperation with European allies, while only around 10 percent favor increased defence collaboration with the United States.

The polling data was released amid growing concerns over what political figures describe as an increasingly volatile global security environment, citing “an aggressive Putin” and “an unpredictable Trump” as factors destabilizing international relations. The Liberal Democrats, who commissioned the poll, argue the current government’s approach to Brexit threatens national security by adhering to restrictions on UK-EU relations set by Labour leadership.

Andy Burnham, the new Labour leader and prime minister, has committed to upholding Sir Keir Starmer’s stance against rejoining the customs union and single market or restoring free movement of people. However, the Liberal Democrats contend this position is dangerous and urge the government to reconsider. They propose a “growth and defence partnership” with Europe, encompassing EU single market membership and the creation of a new UK-EU security council. According to the party, such a partnership would not only respond to security threats posed by Russia but also enhance the UK economy by supporting high-skilled manufacturing sectors like aerospace and shipbuilding.

The poll also found that one-quarter of Reform UK voters support prioritizing defence ties with European allies, suggesting cross-party backing for closer collaboration on security matters. Liberal Democrat Europe spokesperson Al Pinkerton described rebuilding defence and trade relationships with Europe as critical steps to boost economic growth and strengthen the UK’s defences. He criticized Labour for maintaining what he called “outdated red lines,” warning these stances pose risks to national security amid current geopolitical challenges.

Pressure on Burnham to reconsider his position is mounting. Former Labour leader Neil Kinnock urged the prime minister not to be constrained by existing policies, emphasizing that those who “love their country” should embrace renewed ties with the European Union. Meanwhile, former Tory chancellor George Osborne recently characterized Britain’s post-Brexit economy as severely weakened and suggested that rejoining the customs union would be the quickest route toward recovery.

Polling expert Sir John Curtice noted that support for rejoining the EU has risen to its highest point since the 2016 referendum but cautioned that political leaders must act promptly to capitalize on this momentum.

A government spokesperson responded by highlighting its efforts to build stronger security relationships both within Europe and through NATO. The official stated, “Europe faces the most dangerous security environment since the Cold War, and we are stepping up alongside our allies to build a stronger Europe in a stronger NATO. That is why we are building an ambitious, close relationship with the EU that will improve our security and unlock good growth in every postcode.”
