2025 Valdostan regional election

The Regional Council of Aosta Valley (Italian: Consiglio regionale della Valle d'Aosta, French: Conseil de la Vallée) is composed by 35 members. The Council is elected for a five-year term. There is only one regional constituency. The President of Aosta Valley is elected by the Council. The electoral law was recently changed by the L.R. 16/2017 and the L.R. 9/2019.^[3]

The election of the Regional Council is based on a direct choice for the candidate and it is possible to express only one preference for the list. If a single party list or a coalition of party lists gets more than 42% of valid votes cast, it is assigned a majority bonus of 21 seats. If no one reaches this threshold, the seats are determined proportionally. For the proportional allocation there are two thresholds: given the largest remainder method by dividing the valid votes cast for all lists and the seats to be assigned, if a party list doesn't reach the minimum quota required, the party list is excluded to the allocation of the seats. However, if a party list gets only one seat during the first allocation of seats, it is excluded and its seat is reallocated.^{[4][dead link][clarification needed]}

In the 2020 regional election, the Valdostan Union (UV) was reduced to 15.8%, its second worst result ever, while the LNVdA came a stronger first. However, after the election, UV leader Erik Lavévaz formed a government composed of the PD, Civic Network (RC), the Valdostan Alliance (AV), Edelweiss (SA) and Mouv'.^[5] Within a year, AV and Mouv' joined forces, while the RC-led Progressive Civic Project (PCP) left the government.^[6] In 2023 Testolin formed a new government, which, differently from Lavévaz's, comprised also For Autonomy.^[7]

The largest regional party UV decided to not participate in the 2024 European Parliament election citing the electoral system.^[8] In late 2023, Mouv' and the AV started a merging process into the UV.^[9] In June 2024, at an extraordinary congress of the UV, the reunion was finally approved.^[10] In December 2024, Laurent Viérin's Valdostan Pride followed.^[11] The Sovereign Aosta Country (PAS) stated that they are open for a coalition.^[10] In July 2024, rumors came out of a coalition between SA, Valdostan Rally (RV), For Autonomy and Evolvendo after they rejected the invitation by PAS.^[12] In October, these parties alongside Renaissance started negotiations for a "centrist, liberal-democratic and reformist" coalition.^[13] In March 2025, PAS announced that they negotiate with UV and did not rule out running as independents on their list^[14] and SA, RV and For Autonomy formed "Autonomists of the Centre" endorsed by Esprì and Evolvendo. Renaissance left the coalition for concerns about RV.^[15] On 6 August 2025, UV and PAS signed an agreement to run together.^[16] In June, PD proposed an alliance for the local and regional elections with UV and AdC.^[17] Shortly before the deadline, UV proposed a coalition with AdC which was rejected by For Autonomy.^[18]

In June 2024, the Centre-right coalition (Lega, FI, FdI, NM, UDC) announced that they plan to run as a coalition.^[19] In April 2025, they were joined by The Valdostan Renaissance (LRV).^[20] LRV formed a joint list with FI.^[21]

In December, Open VdA (M5S, AD–GA, SI/ADU) announced its intention to run on a joint list.^[22] In February 2025, Erika Guichardaz stated that PCP "ceased to exist" and excluded running on a list which goes from RC, via Power to the People to Legambiente.^[23] On 22 April 2025, RC announced that they will run with Greens and Left Alliance.^[24] Risorgimento Socialista and Communist Refoundation Party joined Open VdA the same day.^[25]
