In the run-up of the 1998 provincial election Lorenzo Dellai formed the Daisy Civic List in order to unite Trentino centrists affiliated with the centre-left into a single political force.

The UpT gained 17.9% of the vote (making it the coalition's and the region's second largest party) anand six seats, plus Dellai's, in the Provincial Council.

On 11 December Dellai was a founding member of Alliance for Italy, which emerged mainly as a centrist split from the PD, along with Francesco Rutelli, Linda Lanzillotta, Bruno Tabacci and Elvio Ubaldi.

In an interview, he pressed forward toward a provincial federation with the Trentino Tyrolean Autonomist Party (PATT) and the local Union of the Centre (UdC).

[17][18] Despite this and the "silence" by Silvano Grisenti (a former regional minister, convicted for corruption and later acquitted, who had forced Fravezzi's replacement and controlled 40% of the party's membership), the UpT seemed far from being united.

[20][21] In late December 2012 Dellai resigned from President of Trentino[22] in order to take part to the foundation of Civic Choice (SC), a centrist party led by Mario Monti.

In the 2014 European Parliament election the UpT endorsed Herbert Dorfmann, top candidate of the South Tyrolean People's Party.

[36][37] In the run-up of the 2015 municipal election in Trento Dellai launched Democratic Civic Construction (CCD), intended to integrate a larger electorate than that of the UpT alone.

[38] The list, which was approved by the provincial board of the party, despite Conzatti's opposition,[39] and could be intended as a move toward an integration of the UpT into the PD,[40] was the third largest in the election.

[42] In October Conzatti, who had lost the support of the party's majority, announced that the UpT would elect its new leadership during a congress in January 2016.

[45] During the congressional campaign, while re-affirming his allegiance to the "autonomist centre-left" coalition and denying any "neo-centrist turn", Mellarini made clear that the CCD should not become a party (its members should be active as UpT members) and that a dialogue with unaffiliated "civic" forces, possibly including PT, should be welcome; on the contrary, Dellai and his supporters explained that his bid was intended to "avoid the genetic modification of the party" and that CCD would continue anyway.

Moreover, the autonomist centre-left coalition was fractured: the UpT-supported PD's candidate won 25.4%, while PATT's Rossi stopped at 12.6%, and both lost to Maurizio Fugatti (Lega Nord Trentino), who went on to win with 46.7% of the vote.
