Ryanair's CEO has slammed the updated travel green list.
From Monday people returning from Cyprus, Finland, Latvia and Liechtenstein will not have to restrict their movements.
Germany, Poland, Iceland and Lithuania are being removed.
Liechtenstein is the only country that doesn't have restrictions for travellers arriving from other jurisdictions.
Ryanair's Michael O Leary is strongly criticising the government's approach to international travel:
"It's just more incredible mismanagement."
"I mean, the joke of this Green List now is that two of the four countries don't have flights from Ireland."
"One of them doesn't even have an airport."
"So they've taken off the three big countries that they added last week too, Lithuania, Germany and Poland."
