Tui has cancelled more holidays to a number of red and amber destinations.
The Government has created a risk-based traffic light system with red, amber and green ratings for countries around the world. The ratings determine the quarantine and coronavirus testing requirements people face when returning to the UK.
Portugal was the only viable major tourist destination on the green list, but it has been put on the amber list.
Most popular holiday locations were already in the amber tier, such as Spain, France, Italy and Greece.
