Covid: Foreign Office still advising against travel to countries set to turn green
One of the UK's biggest xoslot travel companies has said it is currently unable to plan holidays to Croatia and Bulgaria because of government advice.
Both countries will be added to the UK's green list from 04:00 BST on Monday, meaning people can travel there without isolating on return.
However the government's travel advice pages for both countries advises against "all but essential travel'.
Industry body Airlines UK said it was causing huge confusion for carriers.
Government travel advice affects operators' and passengers' insurance and so many are unable to offer holidays there unless this advice changes.
When previous UK green lists have been announced, the travel advice to newly listed "green" countries has been updated to allow non-essential travel.
