British tourists could be stopped from entering Portugal next week, as the EU is recommending the non-essential travel ban stays in place for member countries.
Portugal is one of just 12 countries placed on England's green list for trave l, meaning that anyone going to Portugal will not have to quarantine when they get home.
But Portugal, which holds the presidency of the EU, currently has to uphold its own ban on non-essential travel - reports Wales Online.
That rule is not set to be discussed by the EU until next week, reports The Times.
Holidaymakers have booked trips to Portugal after England's travel ban was lifted, with people allowed to travel from Monday.
But despite UK rules, holidaymakers still have to comply with the rules in the countries they plan to visit.
The Portuguese cabinet is to meet to discuss the issue today, an official said: “If they don’t resolve it the alternative will be thousands of British visitors being turned away at the airport, which is not a good scenario."
The government has confirmed they expect to update the green list of countries people can travel to without quarantining on June 7.
The Prime Minister's official spokesperson said the green list would be updated every three weeks to "give a level of certainty" to holidaymakers and the travel sector, and that this would take effect from May 17, the day the list comes into force.
That means the first update of the list should be expected on June 7.
But it's been reported major destinations major tourist destinations including France, Spain and Greece are unlikely to feature on the government's green list when it's reviewed.
The British Virgin Islands and a raft of Caribbean countries are said to be the likely few to be among the small number of more easily accessible destinations in a month's time.
Travel will operate under the system with countries placed on green, amber or red lists that determine the level of quarantine and PCR test requirements when you're back in the UK.
A third updated list is likely to be revealed in time for a review of the Government’s foreign travel policy on June 28.
