Spain is the latest country to have announced a ban on British holidaymakers.
From Tuesday, it will close its borders to air passengers from the UK, with the exception of Spanish nationals and those legally resident in Spain.
It joins more than 40 countries who have banned British visitors or imposed greater restrictions on UK arrivals due to a discovery of a new variant of the coronavirus in the southeast of England.
Eurostar has also suspended its passenger services to Paris, Brussels, Lille and Amsterdam on Tuesday and the Port of Dover has closed to outbound traffic.
Eurostar is expecting to operate trains from Paris to London tomorrow, but it won’t operate any services from other EU cities to the UK.
It said it will confirm its timetable for Wednesday on Tuesday.
The UK government has already banned travel, including overseas holidays, for residents of London and the South East of England as part of new Tier 4 Covid restrictions and Prime Minister Boris Johnson has asked those living in other tiers to reconsider their travel plans.
Airlines have been temporarily banned from flying from the UK to several countries around the world, but they are allowed to continue to Spain for Spanish nationals or those legally resident in the country.
Greece is one of the few European countries still letting Brits in, but they must isolate for seven days.
