This type of ballot has the advantage of securing a measure of representation for minorities in plurality/majority systems. The reason for this is that the party likely to obtain the majority has no interest in putting up a number of candidates equal to the number of seats to be filled because, if it did so, it would no longer be sure of obtaining a majority as a result of the dispersion of votes. Strategically, therefore, it is compelled to present a number of candidates equal to the number of votes available to each elector in order to optimise its chances of obtaining a majority. This therefore enables minority parties to be represented.
