Article 89 provides that the National Assembly will be composed of at least 101 parliamentarians, elected through a proportional contest which “shall secure the formation of a stable parliamentary majority in the National Assembly” (paragraph 3). A second round of the vote “with the participation of the two parties or pre-electoral alliances that received the largest number of votes” is envisaged “if a stable parliamentary majority is not formed as a result of the first round of the National Assembly election” (paragraph 4). The main features of the chosen electoral system are therefore the proportional allocation of seats, the constitutional goal of stability and the second round between the two most voted parties or alliances. Moreover, in this system, the total number of Parliamentarians is not fixed in the Constitution: it will depend on the number of additional seats possibly allocated as majority bonus.
