In the May 11 elections, following recent changes to the Electoral Code, the preferential vote will once again impact the determination of which candidates will secure a mandate for the 2025–2029 legislature.

Unlike the April 25, 2021 elections, this time the preferential vote will not affect all candidates, but only those placed on open lists. For these candidates, there will be no threshold requirement; instead, only the number of votes they receive compared to other candidates within the same party will matter.

This means that if candidates are listed alphabetically on the ballot, after vote counting, they will be reordered, and the most voted will move to the top—awaiting a mandate based on the number of seats the party or coalition wins.

Depending on how many mandates a political entity gains from the open list, the candidates who received even a single vote more than others will go to Parliament.

On the ballot, voters can choose a party and one of its candidates, only a party, or only a candidate. The ballot will be considered invalid if two parties are selected in different columns or two candidates from different parties are marked.
