The number of countries on the UK Covid travel red list will be cut from 54 to seven, the government says.
South Africa, Brazil and Mexico come off the red list, which requires travellers to quarantine in an approved hotel at their cost for 10 full days.
Transport Secretary Grant Shapps said the changes begin on Monday and “mark the next step” in opening travel.
This latest move will be seen as a boost to the airline industry and families separated during the pandemic.
Panama, Colombia, Venezuela, Peru, Ecuador, Haiti and the Dominican Republic remain on the red list.
Pandemic travel rules in the UK have recently been simplified, with the amber list cut, and advice against holidays changed for 32 countries.
