The question of nationalism within the United Kingdom is not a new one. The popularity of self-governance and separatism has ebbed and flowed, but it has been a constant force that has strafed against the Union. If Boris Johnson is truly intent on preserving the United Kingdom then he would do well to look to others who have navigated the nationalist question.
One such figure is surely David Lloyd George, the architect of the modern UK settlement who secured the union of Great Britain and Northern Ireland by resolving the Irish question during the post-war coalition. For all this, however, he spent much of his career as the gadfly on Welsh issues. During the 1890s, the ambitious MP for Caernarfon was the unofficial leader of Wales in all but office and name, heading the patriotic Welsh group Cymru Fydd (Young Wales).
