Portugal may soon be included to the quarantine-free travel list, if coronavirus cases in the country continue to drop.
The holiday destination favourite could be added to the 'safe-list' in weeks meaning British tourists would exempt from the 14-day isolation on their return.
Ministers are said to be happy that cases in Portugal are now at a safe level but are monitoring the progress in 'weeks' rather than 'days.'
They are reportedly discussing options to add Portugal to the list of 'safe' countries and the change could come into effect by the end of the summer.
Portugal may be included on the 'safe' list for British tourists in weeks if cases remain low
Portugal was excluded from the list of countries that are exempt from quarantine that was published by the UK Government in July.
The list has since been updated but Portugal has continued to be left off the list of 'travel corridors' amid fears at its level of coronavirus infections.
The decision promoted anger from Portuguese officials at the time as Portugal relies heavily on tourism.
Portugal's Ministry of State and Foreign Affairs said: 'It is a decision that is neither substantiated nor supported by the facts.'

According to The Sun, this decision could be reversed if cases in Portugal remain low for the next few weeks.
However, Whitehall officials reportedly don't want to signal the go-ahead to holidays on the Algarve only to have to swipe them if cases start to rise again.
A Whitehall source told The Sun: 'Portugal has made a lot of progress but the process of for dropping quarantine is far more gradual, where we monitor progress in weeks rather than days.'
This will likely delay the green-light being given for another two weeks.
