There are several countries within the European Union that have open borders with each other. Travel between them does not need a passport. Although the UK is part of the European Union, it does not have open borders and so a passport is needed to enter the country.
The requirements for entry vary depending on nationality and the passport held so it is important to contact the UK embassy or consulate to confirm the requirements before travel.
