All travel corridors are being scrapped from 4am Monday in an attempt to curb coronavirus cases - but how will the new rules affect you?
The new measures come after a travel ban was announced on arrivals from South America, Portugal and Cape Verde due to the emergence of a new variant in Brazil.
It means arrivals from every destination will need to self-isolate for 10 days, or receive a negative result from a coronavirus test taken at least five days after they enter the UK.
The previous travel corridors exempted arrivals from having to complete the isolation period on return to the UK. Do I need to get a negative test if I want to come back to the UK?
