UK to leave EU

[Pat Mustard]

Do you think the EU will agree to closed or semi-open borders with the UK though? The UK want access to the European market, and the EU have been pretty adamant about having open borders as a requirement.

Freedom of movement of people within the EU is one of the "four freedoms" the fundamental base of the common market. Unless the UK agrees to it (probably in Schengen form, meaning less freedom than they have now inside the EU), then no access to the common market. They'll be allowed trade with the EU all right, but it'll be a lot harder, especially for the financial sector which is a disproportionately large share of the UK economy (especially seeing as the City of London* is the world's largest offshore tax haven by a few orders of magnitude).

*The Square Mile has a unique political situation inside of the UK, stemming from rights granted to it by various monarchs in the medieval period which have essentially meant that parliament or the crown have no sovereignty over it, i.e. the UK's laws have much less of an effect within the Square Mile than in the rest of the country, excepting the Duchy of Cornwall (which has also got medieval exceptions which supersede UK law in certain vital areas, e.g. if you die intestate within the boundary of the Duchy, Prince Charles automatically inherits your estate).
