It is most popularly associated with candidates in elections for the Parliament of Northern Ireland. Such candidates supported the positions of Unionism in Northern Ireland but, for various reasons, could not reconcile to themselves to the Ulster Unionist Party or other groups. It was also used by Unionists in what became the Irish Free State, as they were unionists, but not in Ulster. The label was also used in Scotland, demonstrating an association with ideology of the Unionist Party, the predecessor to the modern Scottish Conservative and Unionist Party.
