Britain is to hold a referendum this summer on whether to leave the EU. Proponents of "Brexit" want to see less immigration and more self-determination; advocates of staying in the union anticipate horrors both economic and human if the country becomes, once again, an "island".
Polls are running neck and neck. Britain is important enough that its departure could deal a mortal blow to the European Union; the Scots and Irish, in particular, are uneasily tied to England's destiny. Meanwhile, the pound is headed south, presumably in search for warmer climes.
