Under this banner, with some variations, the Valdostan Union (UV) has participated in Italian general elections, along with its allies (sometimes also countrywide parties), which have changed from time to time, since 1983. Since its foundation, the list has won most of the races for both houses of the Italian Parliament (see parliamentary delegations from Aosta Valley).
In the 2006 general election an alternative, centre-left coalition called Autonomy Liberty Democracy (ALD) was formed as Valdostan Renewal (RV), a split from the UV, had joined forces with the Democrats of the Left (DS) and minor parties. In the election the UV-led coalition, named at the time Autonomy Progress Federalism Aosta Valley (Vallée d'Aoste Autonomie Progrès Fédéralisme, VdA–APF), was soundly defeated in both races for the Italian Parliament for the first time since 1972, when the UVP joined forces with the Italian Communist Party (PCI). In the election for the Valdostan seat in the Chamber of DeputiesMarco Viérin (SA, VdA) lost 43.4% to 30.7% to Roberto Nicco (DS, ALD),[1] while in the Senate race incumbent senator Augusto Rollandin (UV, VdA) was defeated 44.2% to 32.0% by Carlo Perrin (RV, ALD).[2]
The UV, SA and the FA presented again the list, simply named Vallée d'Aoste, in the 2008 general election. Antonio Fosson (UV, VdA) defeated incumbent senator Perrin 41.4% to 37.4%,[3] while Ego Perron (UV, VdA) was narrowly defeated by incumbent deputy Nicco, who had joined the newly-formed Democratic Party (PD), 39.1% to 37.8%.[4] After two years of absence, the coalition made thus its return to the Italian Parliament. Under a new electoral law, which included coalitions and a majority premium for the winning coalition, VdA ran together also in the 2008 regional election, gaining 62.0% of the vote and a stable majority in the Regional Council.[5] For the 2009 European Parliament election UV signed an apparentment with the centre-right The People of Freedom (PdL).
In July 2015 the regional government, led by Augusto Rollandin since 2008 (Rollandin had been President of Aosta Valley in 1984–1990), was enlarged to the centre-left PD.[14] In June 2016, after months of negotiations, the government was joined also by the UVP.[15][16] In March 2017 the UVP, SA, Autonomy Liberty Participation Ecology (ALPE) and For Our Valley (PNV) formed a new government without the UV, under President Pierluigi Marquis (SA).[17][18][19][20] In October Marquis resigned and was replaced by L. Viérin (UVP) at the head of a coalition composed of the UV, the UVP, the PD and the Valdostan Autonomist Popular Edelweiss (EPAV),[21] the latter formed by a pro-UV group of splinters from SA who had not endorsed Marquis' government in the first place.
In the 2018 general election VdA, also known as Tradition and Progress (Tradition et progrès–Vallée d'Aoste, TP–VdA), was composed of the UV, the UVP, the PD and the EPAV, as the regional government.[22] The candidate for the Senate was Lanièce (UV), that for the Chamber Alessia Favre (UVP).[23] Lanièce was re-elected to the Senate with 25.8% against 23.2% of his closest opponent, Luciano Mossa of the Five Star Movement (M5S), while Favre obtained 21.7% of the vote and that was not enough to beat Elisa Tripodi of the M5S, who was thus elected to the Chamber. It marked the first time that a candidate not supported by a regionalist candidate won.
