No practical changes in border controls after Brexit
The United Kingdom leaves the European Union (EU) on 31 January 2020. The withdrawal agreement means that throughout 2020, British citizens and their family members will have the same rights to reside in Sweden as before.
During the transition period, British citizens will keep their right to free movement, which includes entry into and exit from the EU. This means that they have the right to enter Sweden with a valid passport or national ID card. A third country national (non-EU citizen) who is a family member of a British citizen needs a valid passport for entry into Sweden. This means that British citizens can use the same line as before when entering or leaving the country.
According to the Passport Act (1978:302), a Swedish citizen can not leave Sweden for a third country (country outside the EU/EEA) without a valid passport. The exception that allows travels with a passport or a national ID card to another EU country will continue to apply for travels to the United Kingdom during the transition period. The United Kingdom will continue to allow EU citizens to enter their territory with a national ID card.
Swedish travelers are always recommended to bring a valid passport when going abroad.
Other EU citizens will be allowed to travel from Sweden to the United Kingdom with a valid passport or national ID card. This is regulated in the Aliens Ordinance (2006:97).
