In June 2025, UK Foreign Secretary David Lammy reaffirmed the British government’s commitment to Gibraltar’s sovereignty following the announcement of a new UK-EU agreement concerning the territory’s post-Brexit status. The deal, which includes provisions for joint border checks and customs arrangements, has sparked debate over its implications for Gibraltar’s political autonomy.
Lammy emphasized that the UK’s position on Gibraltar’s sovereignty remains firm, stating that it is “not up for negotiation.” He highlighted that the agreement was reached with the full support of Gibraltar’s government and was designed to enhance regional stability and prosperity without compromising British control over the territory. The deal aims to facilitate the free movement of people and goods between Gibraltar and Spain, while maintaining the integrity of the UK’s overseas territory status.
Despite these assurances, some critics have expressed concerns that the agreement could pave the way for increased Spanish influence over Gibraltar. Opponents argue that allowing Spanish officials to conduct border checks at Gibraltar’s airport and port could undermine British sovereignty. However, Lammy and other government officials have countered that these measures are practical solutions to post-Brexit challenges and do not alter Gibraltar’s constitutional status.
The UK government has also pointed to the support of Gibraltar’s Chief Minister, Fabian Picardo, who has publicly endorsed the agreement and reiterated that it does not affect the territory’s sovereignty. Picardo’s backing underscores the collaborative nature of the negotiations and the shared goal of ensuring Gibraltar’s continued prosperity within the framework of the UK’s international relationships.
In summary, while the new UK-EU agreement introduces changes to border and customs procedures involving Gibraltar, the UK government maintains that these adjustments do not compromise the territory’s sovereignty. David Lammy’s statements reflect a consistent stance that Gibraltar’s status as a British Overseas Territory remains secure, and the government remains committed to supporting its interests in all negotiations.
