Alex Guest discusses the UK-EU Agreement on Gibraltar in LBC Radio

16 July 2026

During the interview, he explained that the agreement is designed to avoid introducing a hard border between Gibraltar and Spain following Brexit. Alex noted that, whilst Gibraltar is not an EU member, the territory will be de facto within the EU Schengen zone now.

Alex highlighted the agreement's significance for approximately 15,000 cross-border workers who travel daily between Spain and Gibraltar, explaining that smoother border crossings will support employment, businesses and the wider regional economy.

He also discussed the agreement's wider economic implications, including the introduction of a new customs framework intended to facilitate trade between Gibraltar and the EU, alongside measures relating to indirect taxation.

Addressing questions on sovereignty, Alex emphasised that the agreement doesn't alter Gibraltar's constitutional status as a British Overseas Territory. Whilst certain arrangements related to customs, taxation and travel will align with aspects of EU law, the agreement doesn't bring Gibraltar within the full scope of EU legislation.

Alex says the treaty is an important framework for cooperation, providing greater certainty for businesses, residents and workers on both sides of the border.
