There are fears British tourists may be sent home from Portugal when they land 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 travel - 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.
That rule is not set to be discussed by the EU until next week, reports The Times.
Thousands of people have booked holidays to Portugal after England's travel ban was lifted - that rike comes into force on Monday.
But despite UK rules, travelers 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. “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,” an official said.
The European Commission won't meet to discuss the travel ban before next week.
