“The EU is part of those discussions, as are several other countries around the world, and it’s obviously important work,” he said.
“What I’d also say is that in a sense this already exists because you need to have a test before you can travel to the UK and, as far as I understand it from the details set out today, the EU proposal is that certification includes both whether you’ve had the vaccine and also whether you’ve recently had a test for those who can’t get vaccinated yet, which is obviously particularly important.
“Therefore it’s something that we’re working with them and others on and it matters that we get the details of this right for international travel.”

“On top of that, many of the vaccination programmes in Europe – which is a place where we frequently go on holiday abroad – are running behind ours.
“Clearly, whether we can go on holiday abroad to places such as Europe depends on what other countries will say and do in terms of foreign tourism.
“There has to be great uncertainty at the moment.”
The full details of plans are not fully known yet, or how much they are likely to impact British tourists heading to the likes of France, Spain and Italy.
The UK Government has suggested one more is understood about the impact of vaccines, it may introduce a system which allows those who have been inoculated to travel more freely.
The Prime Minister’s official spokesman said: “We have said that we are looking at the issue of vaccine passports.
However, one travel expert has predicted the new “green pass” may not impact Britons’ ability to travel.
“I believe that a vaccine passport will not be necessary in order to travel to the EU, but will probably be used to either eliminate or reduce any quarantine time at arrival at your destination and on return home to the UK,” Neil Wright, founder and managing director of CoverForYou told express.co.uk.
Mr Wright continued: “It would make sense for the UK to follow suit as this is clearly a way in which travel, which supports so many jobs in the UK, can be safely opened up.
“A standard Covid vaccine passport will allow for normal holiday travel to be a real possibility this summer and should be welcomed.”
