The government is set to issue its latest update to the traffic light system this Thursday.
Ministers are currently deciding how travel restrictions will change - and Transport Secretary Grant Shapps will announce which countries will move to the green list - as well as which countries will be hit with tougher quarantine restrictions - as Mirror Online reports.
Reports suggest the government is considering plans to introduce a new amber watchlist - which experts in the travel industry have warned will jeopardise trips to popular travel destinations.

The proposals for the new category has reportedly caused a rift between Cabinet Ministers as fears have mounted hotspots such as Spain and Italy could be added to the new watchlist.
Another big update is set to involve France - which is anticipated to be moved from the amber-plus category.
In addition to Thursday's announcement, travel rules eased today so that fully vaccinated arrivals to the UK from the EU and US no longer need to quarantine.

Here is the full run-down of the latest travel updates and what this could mean for your summer holiday plans, according to Mirror Online.
New countries expected to be added to the green list
Thursday's updates will reveal which countries will be added to the green list where UK tourists can visit without needing to quarantine.
Reports suggest around a dozen nations could be added to the green list for quarantine-free travel.
There are growing hopes that Germany and Italy are among the popular travel destinations which may be deemed safe for travel without jet-setters having to self-isolate on their return.
Analyst Paul Charles, chief executive of travel consultancy The PC Agency, predicted that potential additions could also include Bosnia, Canada, Czech Republic, Hungary, Latvia, Lithuania, Poland, Romania, San Marino, Slovakia and Slovenia.
Arrivals from the EU and US no longer need to quarantine
Mandatory self isolation rules have been eased for fully-vaccinated arrivals from Europe and the US as of 4am on Monday.
People who received their jabs abroad were not included in the relaxation of quarantine for fully vaccinated travellers returning from amber list countries.
But from Monday, expats who were vaccinated abroad will now be able to avoid isolation.
Arrivals will need to prove their jab has been approved by EU or US regulators to prevent lower quality vaccines impacting on the UK's fight against Covid.
France could move category
One of the big updates expected in Thursday's announcement is set to involve France - which was controversially moved to the amber-plus list last week.
The decision meant France is the only EU country from which people vaccinated under the UK programme must self-isolate for 10 days when they return.
However, it is expected France will be moved after Thursday's announcement as Covid cases are falling in the country - and the amber-plus category could even be axed altogether.
An amber watchlist could be introduced
Concerns have been raised today over plans the government could introduce a new amber watchlist warning holidaymakers that countries with concerning coronavirus data could be placed on the red list at short notice.
Current travel restrictions mean travellers returning from a red list country must enter a quarantine hotel at a cost of £1,750 for solo travellers.
And holiday destinations such as Spain could be placed on this list which could put thousands of summer holidays at risk.
How is it decided which countries are red, amber or green?
The traffic light system is based on a number of factors, which include vaccination rates, the rate of infection, genomic surveillance capability - and variants of concern
