Ms Elizabeth Canavan:

Again, it is actually part of the EU regulation that it cannot be a barrier to travel. It cannot be a requirement to travel, just to be clear. We do not want to conflate those two things. It is actually a requirement under the regulation that it cannot be used to prevent travel. It is there to facilitate travel. It is a proof that all countries understand its validity, how robust it is and that it is verifiable. That is what it is. Some countries are saying that is the standard they require. We cannot determine what other countries will say but the information on what standard they require is available on that re-open EU website. We would say to people that it is the highest standard of proof for travel within the EU.
