“But for Scotland, Northern Ireland and Wales the current rules still apply.
“It is absolutely boggling but basically the good news is that holidays 2020 can begin for people who want to go abroad.”
So which countries will Britons be able to go to when the list is published?
“We are still playing lockdown destination bingo, frankly,” said Calder.
“I can tell you some of the countries that we know, because the government has said – France, Germany, Greece, Italy and Spain.
“Greece, of course, won’t allow any direct flights from the UK, until July 15 anyway.
“Then Grant Shapps the transport secretary has let it be known this morning that New Zealand, which we can’t go to either, as well as the Vatican City, the Falkland Islands and plucky Gibraltar are also, on the list where it’s okay to go.”
There are limits to the countries on the list though, and some much-loved destinations will not feature.
“This is all based on the trajectory and indeed the rate of infection and basically looking at all the European countries, I think almost everywhere in the European Union, including Portugal will be clear – Sweden won’t,” said the expert.
“I’m very optimistic that Turkey will be, but I fear that the North African countries Morocco, Egypt and Tunisia will not, and the United States is most certainly not getting on the list and neither is Mexico.”
In Calder’s expert opinion, if the countries are on the approved list then Britons are safe to book.
“If you’re going to any of the aforementioned countries, then you can book fairly confidently if you are in England,” he said.
“We’re not going to know the actual list until this afternoon,” Calder continued.
“So I’m afraid that until then it is just making guesses.”
However, if you’re looking for advice be sure to seek it from the industry experts.
“If you do want to book a holiday it’s always best to talk to an excellent travel agent,” Calder recommended.
