Speculation is mounting that some destinations, such as the Balearic islands and Malta, could be added to the green list at the next review due on Thursday (24 June).

While allowing fully vaccinated travellers to return to England from amber countries without having to quarantine for 10 days is also being discussed.

The Daily Mail has reported that fully vaccinated travellers may not have to quarantine when returning from amber countries from 19 July, the new date for the final unlocking of all remaining Covid-19 restrictions in England.

Prime minister Boris Johnson is being pressed by colleagues to make this move which would open up travel to destinations including Spain and Greece this summer. Children who have not been vaccinated will also be able to travel with their parents.

The decision is expected to made by ministers at a meeting within the next 48 hours and could also involve the government lifting its advice against going on holiday to countries on the amber list.

Meanwhile, Malta and the Balearic islands could be added to the green list this week, according to The Times, which would put key destinations Ibiza, Majorca and Menorca back on the travel map.

Malta could also benefit from having Europe’s most advanced vaccination programme with 80% of the population now having received one dose of a vaccine and just one Covid case per 100,000 people in the past week.
