Brexit vote on June 23. For good or for bad the EU was designed to make it not easy to escape. Every EU citizen and resident is under a complex set of interlocking regulations regarding mobility, residency, marriage, employment, health care coverage, other "benefit" coverage, etc. If the UK leaves the EU, then...? Do they get chucked off the continent immediately? Does it cause trouble for marriage co-residencies (Britain was already mucking that up by basically making it impossible for poors to bring their spouses in)? What will happen to all of those Spanish holiday properties when the Visa requirement kick in?
To the extent that actual consequences have been focused on, it's been on the banking system, the economy, and finally getting rid of those pesky immigrants (some of them, anyway), Consequences for most Brits? Nobody knows...
