The first merit of proportional representation is that it secures representation to all parties and groups in the nation in proportion to their voting strength. It makes the legislature a true mirror of the nation, as it must be in a democracy, based on equality and liberty. Secondly,<\/em> every minority has and equal chance to win seats in the legislature, especially if it is a racial, linguistic or religious minority which is permanent in character and can never hope to become a majority.

Thirdly,<\/em> the very fact that the single transferable vote system is a complicated affair and makes it necessary for the voter to. indicate his preference has an educative value.<\/p>
