People from the UK are subject to a general ban on entering Switzerland. Switzerland has banned foreign nationals from entering from the UK and South Africa. The government said it had decided to “withdraw freedom of movement privileges from persons resident in the UK until December 31. Persons from the UK are therefore subject to a general ban on entering Switzerland. Freedom of movement privileges for British citizens were due to expire at the end of the year anyway.”
