The European Union, United Kingdom, Spain, and Gibraltar have reached a political agreement in principle on Gibraltar’s future border arrangements, resolving one of the last major issues left over from Brexit. Announced on June 11, 2025, the deal sets the stage for the territory’s entry into the EU’s Schengen area and the creation of a new customs union framework between Gibraltar and the EU.
Land Border Barriers to Be Removed, Treaty Still to Come
The agreement, which still requires a formal treaty to be drafted and ratified, aims to eliminate land-border checks between Gibraltar and Spain. Once implemented, the arrangement will allow for the free movement of people and goods across the border, significantly benefiting the estimated 15,000 cross-border workers who travel between Gibraltar and Spain each day.
“This is a truly historic milestone,” said EU Trade Commissioner Maroš Šefčovič, describing the accord at a press conference in Brussels. The agreement maintains British sovereignty over Gibraltar while aligning the territory with EU border and customs procedures to support regional prosperity and reduce friction.
According to the official joint statement issued by all four parties, “The main objective of the future Agreement is to secure the future prosperity of the whole region.”
Shared Border Control and Upcoming EU Biometric Systems
While land checkpoints will be dismantled, Gibraltar’s airport and seaport will adopt a system of dual – or “juxtaposed” – controls. This means that Spanish border officials will carry out Schengen entry checks inside Gibraltar alongside UK/Gibraltar authorities conducting their own. The arrangement mirrors existing procedures on some cross-border rail lines like the Eurostar.
Control of Gibraltar’s external border will be shared under the future treaty. Spain will perform Schengen checks, while the UK retains responsibility for its own immigration enforcement and military autonomy. These compromises are designed to balance practical integration with longstanding sovereignty positions.
The announcement comes amid broader updates to EU border policy, including the May 2025 launch of the Shared Biometric Matching Service (sBMS), the first component in the EU’s new interoperability framework. The Entry/Exit System (EES)—a major biometric border management program—is scheduled to go live in October 2025, further modernizing the EU’s external border infrastructure.
The deal also addresses the legal uncertainty created by Gibraltar’s exclusion from the UK-EU Trade and Cooperation Agreement. With this new framework, all parties aim to provide long-term stability, support cross-border employment, and ensure the smooth flow of goods and people across the region.
