*151. Two-Party Organization.*--The relationship which subsists (p. 144) between parliamentarism and party government is to be accounted for in no small measure by the fact that the number of great parties in the United Kingdom is but two. Certain continental nations, notably France and Italy, possess the forms of parliamentary government, adopted within times comparatively recent and taken over largely from Great Britain. In these countries, however, the multiplicity of parties effectually prevents the operation of the parliamentary system in the fashion in which that system operates across the Channel. Ministries must be made up invariably of representatives of a number of essentially independent groups. They are apt to be in-harmonious, to be able to execute but indifferently the composite will of the Government coalition in the popular chamber, and, accordingly, to be short-lived. Despite the rise in recent decades of the Irish Nationalist and Labor groups, it is still true in Great Britain, as it has been since political parties first made their appearance there, that two leading party affiliations divide between themselves the allegiance of the mass of the nation. The defeat of one means the triumph of the other, and either alone is competent normally to govern independently if elevated to power. This means, on the one hand, a much more thoroughgoing predominance of the governing party than can be acquired by a single party in France or Italy and, on the other hand, a unique concentration of responsibility and, in turn, an increased responsiveness to the public will. The leaders of the one party for the time in the ascendancy govern the nation, by reason of the fact that, _being_ the leaders of this party, they are selected without doubt or equivocation to fill the principal offices of state.[210]
