Canada, Denmark, Finland, the Azores, Switzerland, Liechtenstein and Lithuania are new seven countries moving to the green list in the latest changes to Covid restrictions.
Thailand and Montenegro are being added to the UK government’s red list – meaning they are considered to be among the highest-risk destinations.
The changes will come into force at 04:00 BST on Monday.
Travellers coming from green list countries do not have to quarantine when they come back to the UK – whether or not they have had two doses of a coronavirus vaccine. They still have to be tested before leaving the UK however and upon their return, and fill in a passenger location form.
Only UK or Irish nationals, or UK residents, are allowed in to the UK if they have been to red list countries. They then have to pay to self-isolate in a government-approved quarantine hotel.
Travel lists are currently updated every three weeks. Most countries are on the amber list -fully- inoculated adults do not have to quarantine on their return from these locations, but should have tests before leaving and when they get back. Those who have not had both vaccines have to isolate at home for 10 days, as well as having the Covid tests.
