In return, Spanish citizens will be allowed to enter Gibraltar using a government ID card.The treaty in effect brings Gibraltar into the EU’s Schengen free-travel area, which allows people from 29 countries to move among them freely without needing visas.At Gibraltar’s airport and port, entry and exit checks will be conducted by both British and Spanish border officials. The arrangement is similar to what’s in place at Eurostar train stations in London and Paris, where both British and French officials check passports.Travellers to Gibraltar from countries outside the Schengen area, including the UK, will have to contend with the EU Entry/Exit System, which was rolled out in Europe in April and replaced passport stamps with biometric data collected through photographs and digital fingerprints.Under the older system, every person had to face two border checks, one by Gibraltarian border agents and the other by Spanish officials when entering or exiting the Schengen area. The checks caused long queues, heavily impacting the workers who made the crossing daily.The British government said the agreement brings “fluidity for people and goods crossing the Gibraltar-Spain border to support economic growth and jobs in the region”.What was the motivation behind the treaty, and how does Brexit feature in it?In a 2016 referendum in which UK voters approved leaving the EU, 96 percent of voters on “the Rock”, as Gibraltar is popularly known in English, supported remaining in the bloc.When Britain eventually left the EU in 2020, the relationship between Gibraltar and the bloc was left unresolved. Previous talks on a deal to ensure people and goods could keep flowing across the border had made halting progress.While the Trade and Cooperation Agreement, which came into force in 2021, broadly covered relations between the bloc and Britain, it was decided that Gibraltar would be addressed in separate negotiations because of its unique situation because it’s not in the EU customs union or the Schengen area.In 2025, the EU and UK announced an agreement on those issues after more than three and a half years of negotiations.Does the treaty place Gibraltar in a special position, and do any other British overseas territories have the same privileges?Yes, Gibraltar is in a unique position because it has now gained EU privileges without being an actual EU member.Still, it is under British sovereignty, and the treaty solely seeks to resolve post-Brexit cooperation with the EU and border management due to its open land border with the EU.None of Britain’s other overseas territories, which include 14 territories scattered across the Caribbean and the Antarctic, has a deal similar to Gibraltar’s due to the shared land border.Some of the territories have international arrangements, including Bermuda, which has its own immigration and tax systems, and the Falkland Islands, which govern themselves.
