The case may be that foreign countries will restrict travel to tourists for some time to come.
The travel industry has breathed a sigh of relief at the prospect of people being able to go on holiday this summer.
Overnight stays in self-contained accommodation that don’t require any shared use will be allowed from April 12 at the earliest.
Paul Charles, chief executive of travel consultancy firm the PC agency, said this was “the news the travel sector really wanted”.
He added: “I’m sure virtually everyone in the travel sector will be pleased with the greater clarity and a timeframe of May for enabling those who’ve been vaccinated to travel overseas.
