The main combinations proposed are the following:
♦ Application of plurality/majority system in some constituencies and proportional representation in the others.
♦ Use of the plurality/majority systems for candidates or lists having obtained the absolute (or qualified) majority and the distribution of the remaining seats on the basis of proportional representation.
♦ In a given constituency, application of the plurality/majority system for a predetermined number of seats and use of proportional representation for the remainder.
♦ Application either of the plurality/majority system or the proportional representation system depending on the size of the constituency.
♦ Use of proportional representation in order to offset the effects brought about by plurality/majority voting. Amongst those systems, mention may be made of “personalised representation” in Germany and the 1994 Electoral Act in Italy.
