The additions mean fully-vaccinated tourists from more than 180 countries and territories worldwide can be admitted to the country.
VisitBritain chief executive Sally Balcombe said: “Britain’s tourism industry is ready to welcome international visitors. We know there is pent-up demand for travel, and our priority is to build back visitor spending as quickly as possible, competing hard for international visitors who contribute billions to our economy.”
This year will prove especially attractive to overseas visitors, with landmark events including the Queen’s Platinum Jubilee, the Commonwealth Games and the Unboxed Festival, previously known as Festival 2022.
