What Brexit would look like for Britain

‘So what’s your alternative?’ demand Euro-enthusiasts. ‘D’you want Britain to be like Norway? Or like Switzerland? Making cuckoo clocks? Is that what you want? Is it? Eh?’

The alternative to remaining in a structurally unsafe building is, of course, walking out; but I accept that this won’t quite do as an answer. Although staying in the EU is a greater risk than leaving — the migration and euro crises are deepening, and Britain is being dragged into them — change-aversion is deep in our genome, and we vote accordingly. Europhiles know that most referendums go the way of the status quo, which is why their campaign is based around conjuring inchoate fears of change.

What is the alternative? Well, all the options involve remaining part of the European free-trade zone that stretches from non-EU Iceland to non-EU Turkey. No one in Brussels argues that Britain would leave that common market if it left the EU.
