Spain, the United Kingdom and the European Union have finally published the long-awaited draft treaty that will govern Gibraltar’s post-Brexit relationship with the continent. Running to more than 1,000 pages and 46 annexes, the document would demolish the physical frontier fence (“la Verja”), fold Gibraltar’s port and airport into the Schengen area and create a joint customs territory covering the tiny British Overseas Territory and the neighbouring Spanish town of La Línea de la Concepción.
Under the proposed “double-key” model, the National Police would conduct Schengen entry checks at Gibraltar’s airport and seaport. Although the treaty stresses that it “does not affect sovereignty,” it hands Madrid a decisive say over who may enter or reside on the Rock: Spanish officers could block any non-EU national—including Britons—on public-security, health or migration grounds, and may deny or revoke residence permits. Spain will also be able to levy a new indirect tax (initially 15 %) and impose a minimum excise duty of €115 per 1,000 cigarettes to curb smuggling.
For businesses the prize is friction-free trade. Gibraltar will join the EU customs union, removing routine goods inspections and enabling just-in-time supply chains for the 15,000 cross-border workers who commute daily. Hauliers will use new inland inspection posts in La Línea, Algeciras and Sagunto, avoiding congested frontier loops. The treaty also lays out mutual recognition rules for professional qualifications, environmental convergence and a three-year timetable to align indirect taxes with mainland Spain.

Whether you’re a commuter, a business traveller or simply planning a holiday that now routes through Spain’s Schengen border, VisaHQ can help make sense of the changing entry rules. Its easy-to-use platform (https://www.visahq.com/spain/) provides up-to-date visa guidance and application services so individuals and companies alike can secure the necessary documentation quickly and stay compliant as the new treaty takes effect.
Politically, the deal is being sold as a “win-win.” Madrid points to the symbolic tearing-down of the last physical border in continental Europe; London emphasises that nothing in the text prejudges sovereignty, while Gibraltar’s Chief Minister Fabian Picardo calls it “a safe agreement that protects our British way of life and unlocks huge economic potential.” Yet critics in Westminster and the Campo de Gibraltar warn of creeping EU jurisdiction and fear higher prices for fuel, alcohol and housing once Gibraltar loses its ultra-low-tax edge.
Ratification still looms. The text must clear the UK and EU parliaments as well as Gibraltar’s legislature. Foreign-minister José Manuel Albares told Spanish TV that he expects signatures “a little before or after the summer,” paving the way for the treaty to enter into force on 10 April 2026, just weeks before the EU’s new Entry/Exit System (EES) goes live. Companies with cross-border staff should begin reviewing immigration policies, customs registrations and indirect-tax compliance now.
