The regional elections that were held in May 2015 have confirmed the changes that have recently been taking place in the politicalparty system in Italy: the end of the bipolar system and the emergence of a third pole consisting of the M5S. The tripolarism at the regional level can be attributed not only to the success of the M5S, but also to the loss of salience of the center-right and the disappointing performance of the center-left. In terms of the political offer, this election round showed an increase in party fragmentation and the average number of candidates and a greater variability in the number and type of coalitions than in previous contests. In terms of results, it showed a greater dispersion of the vote between the candidates for the presidency and identified the M5S and the LN as the two axes on which the new balance of power in the regions is centered.
