I am not commenting on what anyone else has said, but we may be affected by the business of Priti Patel's idea.

My Italian daughter-in-law's father is visiting her from his home in Milan at the start of November. It is completely unclear whether he will be able to. In time, I would imagine a visitor's Visa would sort it.   But as of today, you cannot apply for one if you live in the EU. And even if you found a way to apply the site says "You should get a decision on your Visa within 3 weeks." Somehow I don't see that getting dramatically faster around the magic date. So unless all this is sorted by mid October, the visit to see his grand-daughter looks as if it might be off.
