The United Kingdom and the European Union have reached their most substantial agreement on trade and defence cooperation since Brexit, signalling a shift toward closer ties after years of strained relations.
Almost nine years after the UK’s decision to exit the EU, the two sides have come to terms on a new arrangement that includes joint defence procurement, improved trade flows for food products, and a new agreement on fishing rights. The reset comes amid global uncertainty and renewed pressure on European nations to strengthen their own security capabilities, especially in light of shifting U.S. policies under Donald Trump.
As Europe adapts to new geopolitical challenges, British Prime Minister Keir Starmer has aligned more closely with leaders like French President Emmanuel Macron. Starmer, who supported remaining in the EU during the 2016 referendum, has also introduced measures aimed at making travel easier for British citizens, including access to fast-track passport lanes at European airports—an effort to win over a divided public.
Standing alongside European Commission President Ursula von der Leyen and European Council President Antonio Costa, Starmer described the agreement as the beginning of “a new era” in UK-EU relations. Von der Leyen emphasized the importance of European unity in a time of global volatility.
The UK government stated that the renewed partnership with its largest trading partner will cut bureaucracy for exporters, especially in the agricultural sector, potentially lowering food prices and improving energy cooperation. The agreement is projected to add nearly £9 billion to the UK economy by 2040.
This is the third major international agreement the UK has signed in recent weeks, following pacts with India and the United States. Although the economic impact is not expected to be immediate, the deals could help boost investor confidence.
Central to the deal is a defence cooperation pact, which allows the UK to participate in EU-led joint military procurement programs. British firms like BAE Systems, Rolls-Royce, and Babcock stand to benefit from involvement in a €150 billion initiative aimed at rearming European forces.
On fisheries, both UK and EU vessels will be allowed reciprocal access to each other’s waters for the next 12 years. In exchange, Britain will benefit from reduced border checks and paperwork—barriers that had particularly impacted small-scale food exporters.
Additionally, the UK has agreed to outline a limited youth mobility scheme, with further negotiations expected, and is in talks to rejoin the Erasmus+ student exchange program.
The new agreement has faced criticism from both Brexit advocate Nigel Farage and the Conservative Party, which was in government during the UK’s departure from the EU and responsible for the initial exit deal.
The 2016 referendum revealed deep divisions across the UK on issues ranging from immigration and national sovereignty to trade and cultural identity. The aftermath included years of political instability, with five prime ministers serving before Starmer took office in July of last year.
Public opinion has shifted in the years since, with most Britons now expressing regret over the decision to leave the EU—though not necessarily in favor of rejoining. Farage’s political resurgence continues to shape the debate, placing limits on how far the government can go in renewing EU ties.
However, joint efforts on Ukraine and shared concerns about U.S. foreign policy have contributed to a thaw in UK-EU relations. Rather than seeking full reintegration into EU frameworks such as the single market, Starmer has focused on targeted improvements, including better trade terms for specific sectors—an approach sometimes criticized by Brussels as selectively seeking the benefits of EU membership without the responsibilities.
To reduce trade barriers on food, the UK had to agree to align with certain EU standards. Starmer is expected to argue that this compromise will boost the economy and bring down consumer prices, a calculation that experts believe will appeal to small businesses and farmers alike.
Still, the UK’s economy remains structurally different from its pre-Brexit form. The departure from the EU has led to job losses and reduced tax revenues in the financial services sector, and the broader economic effects continue to unfold.
