A landmark post-Brexit treaty negotiated by Prime Minister Keir Starmer's Labour government will grant the European Union sweeping new powers over Gibraltar, including full control of its borders and significant influence over its tax system. The agreement, which has been met with fierce criticism from Eurosceptic MPs and veterans, represents a major shift in the governance of the British Overseas Territory, raising profound questions about the erosion of British sovereignty.
Spanish Border Guards to Operate in Gibraltar for First Time
Under the terms of the newly published draft treaty, Spanish border guards will be stationed within Gibraltar for the first time in history. These officials, who have previously faced accusations of being overly zealous in conducting crossing checks, will wield the authority to block British travellers from entering the territory if they are deemed to pose a risk to security or international relations. This unprecedented arrangement marks a significant concession to Madrid and Brussels, fundamentally altering the dynamics at the border.
Immigration Checks Shift to Airport and Port
The treaty stipulates that all immigration checks will now be conducted at Gibraltar's airport and port, rather than at the land border with Spain. Gibraltar Airport, which is operated by the Ministry of Defence and houses an RAF base, will become a key point of entry control. This move is designed to facilitate a "fluid border" on land, allowing the approximately 15,000 people who cross daily to pass without routine passport checks, effectively integrating Gibraltar into the EU's free-travel zone, though ministers insist it is "not joining Schengen."
EU Gains Authority Over Tax and Customs
In addition to border control, the European Union will acquire new powers over Gibraltar's tax regime, bringing an end to the territory's current VAT-free system. The treaty establishes a "bespoke" customs union with Brussels, meaning that the majority of goods entering Gibraltar will be cleared by EU officials based in Spain. This integration extends to regulatory alignment, with Gibraltar required to adhere to EU single market rules and fall under the jurisdiction of the European Court of Justice.
Political Backlash and Sovereignty Concerns
The 1,018-page draft treaty has ignited a firestorm of controversy in Westminster. Eurosceptic MPs and veterans have condemned the deal as a "humiliating surrender" of British territory, arguing that it undermines the UK's sovereignty over Gibraltar, which was ceded by Spain to the British crown in 1713. Reform UK has echoed these sentiments, branding the agreement a capitulation.
While UK ministers have asserted that the treaty does not affect sovereignty and includes clauses stating that nothing signed "shall constitute the basis for any assertion or denial of sovereignty" over The Rock, critics remain unconvinced. Shadow foreign office minister Wendy Morton cautioned that sovereignty is "not simply about words, it is about how arrangements operate in practice," highlighting the practical implications of Spanish guards having the power to "make arrests and take other coercive measures" on Gibraltarian soil.
Treaty Aims for Fluid Border and Removal of Barriers
The draft treaty outlines ambitious plans for a seamless border between Gibraltar and Spain, including the removal of the substantial barbed wire fence that has long separated the two. This "dual" border model, akin to the French police operations at St Pancras station in London, aims to streamline cross-border movement for people and goods, though it introduces new complexities with Spanish authorities operating within British territory.
Despite the backlash, the treaty has been celebrated by the Spanish government and welcomed by the Gibraltar administration. However, it still requires ratification by Parliament and formal signing, setting the stage for further political debate and scrutiny over the coming months as the implications of this historic deal unfold.
