Foreign Secretary Lord David Cameron is visiting Brussels on Friday for discussions on Gibraltar's post-Brexit relationship with the EU.
The meeting will be attended by Gibraltar Chief Minister Fabian Picardo, Spanish Foreign Minister Jose Manuel Albares, and European Commission Vice President Maroš Šefčovič.
The main topic of the talks is expected to be managing Gibraltar's border.
However, a final agreement is not anticipated.
Gibraltar's Chief Minister, Fabian Picardo, is optimistic about the outcome of the talks and wants to advance matters while maintaining the territory's sovereignty.
Gibraltar, a British territory on the Iberian peninsula, faces issues due to the UK's exit from the EU in 2016 and the end of free movement.
Thousands of people cross the border with Spain daily for work, shopping, or family visits.
Gibraltar was not included in the permanent Brexit deal and instead operates under temporary arrangements.
Since October 2021, there have been 17 rounds of talks to find a permanent solution.
Recently, Conservative MP Sir Bill Cash expressed concern over reports that the UK had agreed in principle to EU border checks in Gibraltar and joint management of its airport by the UK and Spain.
The European Scrutiny Committee chair raised concerns over potential restrictions for Gibraltar residents crossing into Spain.
The UK government, represented by Foreign Office Minister David Rutley, stated their opposition to any agreements that infringe upon Gibraltar's sovereignty.
