UK nationals or residents will be able to return to Britain from Denmark – but will have to isolate along with all members of their household for 14 days.
The new rules update regulations that came into force just a day earlier.
The transport secretary announced the changes shortly after 2am – less than two hours before they took effect.
Officials will contact anyone in the UK who has been in Denmark in the last fortnight to make sure they also self-isolate.
Denmark had been taken off the UK coronavirus travel corridors
list on Friday after it first became apparent the mutated form of coronavirus was present in the country. It meant any passengers arriving in the UK from Denmark would need to self-isolate after their arrival.
