The general elections of most countries with parliamentary systems have largely functioned in the same way. They have had some regular alternation between two parties, one ostensibly left-of-center and one ostensibly right-of-center. In these systems, there has been little difference between the two main parties in terms of foreign policy and only a limited set of differences on internal politics, centering on issues of taxation and social welfare.
