In the 2008 regional election the party externally supported the winning centre-right regionalist coalition composed of Valdostan Union (UV), Edelweiss (SA) and Autonomist Federation (FA).

In the 2018 regional election the party, whose list was led by Spelgatti, obtained 17.1% of the vote and seven seats.

[18][19] The government proved short-lived: in December it fell down and was replaced by a new one led by Antonio Fosson (PNV), at the head of a coalition composed of the Valdostan Union (UV), the Progressive Valdostan Union (UVP), ALPE and SA.

[25][26] The party has never achieved a popular support comparable to the main national sections of the LN, due to the presence and electoral strength of other regionalist parties, notably including the Valdostan Union, Edelweiss, the Autonomist Federation and the Progressive Valdostan Union.
