As a Swedish national doing business with clients in London, I fear the implications of this. As it were, I was able to stand up my business and start working with clients in London in a matter of a couple of weeks (with the lion's share of bureaucracy being Swedish, not cross-state.) No VISAs, no satellite entities, no special tax lawyers, just get a Swedish company up and start working with the UK. Done.

The EU may be flawed in many ways, but the free movement of people, goods, and services ain't one. Unfortunately, that flies squarely in the face of the leave campaign's "controlling the borders" message.

Sad day today.
