What effect would a successful campaign for Scottish independence have for Ireland? Would Northern Unionists owe allegiance to London or Edinburgh? Would those of Scots Presbyterian ancestry look to Scotland and those of Anglo-Irish stock to London? What difference would it make to them if Scotland retained the monarchy under a Hapsburg dual monarchy-type system? It was suggested to me by a fairly intelligent observer 15 years ago that Scottish Independence would lead to civil war in Ireland, is that hyperbole or does it have any substance? I wonder if any unionists have any opinions, particularly on the question of allegiance..
