Speaking to the BBC, Harry Theoharis said anyone entering Greece from a UK airport on the EU Aviation Safety Agency’s list of airports that are considered to be a risk would be tested and face seven days’ quarantine, regardless of result.

The restriction will apply from 15-30 June and then be reviewed.

EASA’s list details airports where enhanced aircraft disinfection is required. It lists 13 UK airports including all the major London airports plus Manchester, Glasgow, Birmingham, East Midlands and Newcastle.

Those not on the list include Edinburgh, Southampton, Southend and Exeter.

Thoeharis said Covid-19 tests were mandatory and would take a day before results were known. Even if the result is negative, Greece would still require a “self-imposed” quarantine of seven days, although this can be in holiday accommodation, he explained.

He acknowledged this would not be practical for those staying for a week or two.

“That’s why this is not going to be for the masses. It has to mean you have more time.”

Travellers will also face UK quarantine restrictions on their return if current proposals are not lifted.
