Britain and EU Hold First Post-Brexit Summit to Reset Ties Amid Global Challenges
London, May 19, 2025 – The United Kingdom and the European Union convened their first bilateral summit since Brexit today in London, marking a significant step toward resetting their relationship five years after Britain’s formal exit from the bloc. Hosted by Prime Minister Keir Starmer at Lancaster House, the summit brought together European Commission President Ursula von der Leyen, European Council President António Costa, and EU High Representative Kaja Kallas to discuss deepening cooperation on trade, security, and geopolitical challenges, including the war in Ukraine and shifting U.S. alliances under President Donald Trump.
The summit, the first of planned annual meetings, produced three key outcomes: a landmark defense and security agreement, a joint declaration on shared foreign policy priorities, and a “common understanding” on future trade and cooperation topics. The defense pact aims to bolster Europe’s military security amid concerns over reduced U.S. commitment to NATO, facilitating cross-Channel defense industry collaboration and structured dialogues on security issues. However, it does not grant the UK access to the EU’s €150 billion Security Action for Europe fund, though future talks may allow British firms to bid for contracts. The joint declaration emphasized support for Ukraine, pressure on Russia, and addressing civilian suffering in Gaza, reflecting shared concerns over global instability.
A major focus was reducing post-Brexit trade barriers, with a significant breakthrough on a sanitary and phytosanitary (SPS) agreement to ease checks on agricultural goods, addressing delays that have seen fresh food spoil at borders. In exchange, the UK made a late concession on fishing rights, granting EU fishers access to British waters until 2038—a 12-year extension from the current deal expiring in June 2026, far longer than the UK’s initial four-year proposal. This has sparked criticism from Brexit supporters, with Conservative Shadow Business Secretary Andrew Griffith labeling it a “surrender summit.”
Starmer hailed the summit as a “milestone for delivery,” emphasizing benefits for jobs, bills, and borders without breaching Labour’s red lines of not rejoining the EU’s single market, customs union, or freedom of movement. Discussions also touched on youth mobility, with the EU pushing for a scheme to allow 18-to-30-year-olds to live and work temporarily across borders, though the UK secured ongoing talks rather than firm commitments, avoiding political backlash from Brexiteers. Other areas for future negotiation include aligning emissions trading schemes, energy cooperation, and mutual recognition of professional qualifications to aid service exporters.
The summit occurs against a complex backdrop. Starmer’s approval ratings have plummeted to -46, driven by domestic discontent and the rise of Nigel Farage’s Euroskeptic Reform UK party, which now leads polls after strong local election gains. Critics, including The Sun and The Daily Mail, have branded the summit a “betrayal of Brexit,” amplifying fears of creeping EU alignment. Conversely, pro-EU Liberal Democrats and over 60 Labour MPs urge bolder steps, such as a customs union or Canada-style trade deal to further reduce barriers.
Global events, notably Russia’s war in Ukraine and Trump’s tariffs and reduced European defense prioritization, have diminished Brexit’s bilateral bitterness, pushing both sides toward cooperation. Analysts like Anand Menon of UK in a Changing Europe note that failure to collaborate would be poorly received internationally. France, a key EU player, has pushed hard on fishing rights, with some speculating that a state visit invitation for President Emmanuel Macron to Windsor Castle in July is a UK diplomatic sweetener.
While the summit’s outcomes are modest—described as a “step forward, not a step change” by trade expert David Henig—the symbolic weight of renewed UK-EU dialogue is significant. Chancellor Rachel Reeves told The Guardian that the summit lays the groundwork for future cooperation, signaling a break from past ideological battles. As negotiations continue toward the 2026 renewal of the Trade and Cooperation Agreement, both sides face political risks: Starmer from domestic Brexit hardliners, and the EU from member states guarding single market principles. For now, the summit underscores a pragmatic shift, with Britain and the EU navigating shared challenges as partners, not adversaries.
