Customs checks still likely at Gibraltar border, despite possible Schengen deal Do you have news? Tell us about it! 1.1k Negotiations are continuing on a last-minute deal that would see Gibraltar become part of the EU’s Schengen area. However, according to El Pais, customs checks on goods between the EU and Gibraltar will still be needed. The Gibraltar Chronicle reports that Gibraltar, the UK and Spain have been negotiating a Schengen-style agreement for that would allow for free movement across Gibraltar’s border with Spain and the EU. If such a deal is agreed, EU citizens would be able to enter Gibraltar without going through passport control. This would allow the thousands of Spanish citizens working on âthe Rockâ to freely cross the border as normal. However, any UK citizens flying into Gibraltar from the UK would be subject to checks.
