Gibraltar’s size is often our greatest challenge. Yet in the context of a UK exit from the EU, our problems, massive though they would no doubt be, would be discernible and identifiable.

I believe that the same would not be true of the economies of each of the distinct nations — Scotland, England, Wales and Northern Ireland — that make up the UK. The effect would stretch beyond the obvious consequences: England’s City of London, whose services would be locked out of the single market; or Airbus Industries potentially leaving Wales; the hurdles and added costs that would encumber the sale of Scotland’s great products, from whisky to knitwear across the EU. There would be the loss of EU funding for Northern Ireland, stymying Belfast City Council’s key objectives in European affairs. In fact, the effect on the lives of millions of Britons, even some of the most Eurosceptic, would be enormous. Supermarket shelves would be affected as much as the market in holidays, with the changing situation faced by UK travelers when arriving on holiday or business at airports and other entry points of EU nations.
