From October 2021, citizens of the European Union, Switzerland, Iceland, Liechtenstein and Norway will require a passport to enter the United Kingdom. The British government will then no longer accept identity cards or ID cards from the states mentioned. The reason for this step is that these documents should not be particularly secure.

UK citizens already need a passport to enter the European Union. But that has to do with the fact that this state does not issue identity cards. Both the driver's license and the National ID card serve as everyday identification. Both are only permitted in Germany for identification purposes. The UK does not accept domestic ID cards as a travel document. So far, citizens of the European Union, Switzerland, Iceland, Liechtenstein and Norway have been able to enter the United Kingdom with their identity cards. The practice is ended by the UK government and justified with the increase in security. It is said that the identity cards are not sufficiently secure.
