The Elizabeth Ford case (and others like her) is an entirely home-grown problem caused by the Home Office's 'hostile environment'. It isn't a Brexit issue, except that EU citizens will now be vulnerable to similar persecution.

The US has always been difficult to enter, even as a tourist. I first visited in 1976, during it's Bicentennial Year, which was perhaps the first time it had marketed itself as a tourist destination. The message appeared not to have reached the immigration officials, who didn't seem capable of imagining that someone might come to America and nevertheless want to go home afterwards. However, from what I hear entering the UK isn't much better, especially if you come from Africa or Asia.

Brexit was sold to us on the basis that we would be able to negotiate a new and positive relationship with the EU. I very much hope that will still be possible, although we have tested their patience and forbearance severely, and that we might be able to put arrangements in place which will allow us to travel for work or pleasure with the minimum of interference. Perhaps when all this settles down the politicians on both sides of the argument will no longer feel they need to take such polarised positions and will be able to make the compromises necessary to reach a deal.
