ATHENS — While Greece on July 1 allowing more tourists into the country, Greeks who want to go to the United Kingdom won’t face a 14-day quarantine there because of Greece’s safer record of dealing with the COVID19 pandemic and holding down the number of cases and deaths.

Official travel advice against all but essential travel outside Britain will also be eased for some countries and regions to make it easier for Britons to travel abroad, said the Reuters news agency, despite the UK’s abysmal record in dealing with the pandemic after Prime Minister Boris Johnson – who contracted the virus – delayed a lockdown.

An expert panel will put nations into three categories: green, amber and red to be assessed for landing in the UK.

Passengers arriving from green and amber countries will no longer have to quarantine themselves for 14 days after their arrival. The categories are due to be announced with the rule changes expected to come into effect after that.

They will be based on factors including prevalence of COVID-19, the trajectory of the disease and the reliability of data with UK officials set to discuss the classification with other countries, including France and Spain that suffered a high number of deaths.
