Denmark has been removed from the British government’s list of travel corridors.
Travellers arriving in the UK from Denmark after 4am on Friday must self-isolate for 14 days.
The transport secretary, Grant Shapps, said: “I understand that this will be concerning for both people currently in Denmark and the wider UK public, which is why we have moved quickly to protect our country and prevent the spread of the virus to the UK.
“Health authorities in Denmark have reported widespread outbreaks of coronavirus in mink farms, with a variant strain of the virus spreading to some local communities. The chief medical officer has therefore recommended that, as a precautionary measure, all those returning from Denmark should self-isolate for 14 days.
“People currently in Denmark may finish their trip, follow the local rules and check the Foreign, Commonwealth and Development Office travel advice pages on gov.uk for further information.”
