"The IPU has noted the need, among others, to strike a balance between two essential considerations: that a legislative election above all must make it possible to designate a cohesive government responsible for conducting a national policy; and that the election primarily must guarantee representation at the national level of the country’s political forces, and reproduce in Parliament as faithful an image as possible of their relative strength. The IPU has also stressed the importance of a reasonable link between the electors and the elected, reflecting those elements of proportionality which also characterize the governing principles of international law."
