A further 10 countries will be added to the green travel list, including Spain and Italy, according to reports.
Currently, there are no viable major summer hotspots on the quarantine-free green list.
Spain, France, Italy and the US are all on the amber list, which means people returning to the UK must self-isolate at home for 10 days.

While the Foreign, Commonwealth and Development Office (FCDO) does not advise against travel to any of these destinations, the Government is urging people to avoid holidays to amber locations.
Paul Charles, chief executive of travel consultancy The PC Agency, was among leading figures in the sector who expressed outrage when Portugal was moved to the amber list last week, as it meant no viable major tourist destination was in the green tier.
Mr Charles claimed: "Portugal and other countries such as Malta, Morocco and Grenada should be on the green list but decisions on restrictions were "highly political, not based on data at all."
However, on June 24 the government will update the green list.
And early reports suggest as many as 10 nations will be added to the green list, effectively giving holidaymakers the green light to book trips and enjoy holidays.

Malta is seemingly a surefire bet to be included in the green list with a case rate of just seven per 100,000 people, reports BirminghamLive.
That figure is lower than the vast majority of England local authority areas.
The US could also be added, with a rate of 31 per 100,000 people.
The Canary Islands was not added to the green list on June 8 when the last review took place.
But there is widespread chat that holiday islands could be separated from mainland territories.
And if so, the Canary Islands are a strong candidate to be included.
As well as Lanzarote, Tenerife and co, the Balearic islands - from Menorca and Majorca to Ibiza - could also be introduced to the green list.
Poland and Mexico, with case rates of eight and 16 per 100,000 respectively, are also candidates.
Italy (27 cases per 100k), Germany (24 per 100,000 people) and Jamaica (14 cases per 100,000) are also in the running.
Finland (a case rate of 14 per 100k) could also be added.
