What is the EU's new border system EES - and how does it work?

The next time you travel from the UK to Europe, you might notice some changes.

The EU's much-delayed new digital border system, the Entry/Exit System or EES, will be gradually introduced this autumn.

The system is meant to strengthen security and ultimately make travel smoother, but there are concerns it could lead to long queues when people first register.

EES is a digital system designed to keep track of when non-EU citizens enter and leave the Schengen Area.

This covers 29 European countries - mainly in the EU - which member citizens can travel across freely without border controls.
