was strongly opposed by Dellai's supporters. In late February the party's board elected Paolo Pipinato, an ally of Mellarini, as president and decided to hold a referendum among party members on the incompatibility clause. In early March the change to the party's constitution was approved and Mellarini took over as secretary. Dellai and his allies, including senator Fravezzi, former senators Tarcisio Andreolli and Mauro Betta, and former secretary Fontana looked likely to leave the party, but chose to stay. In December Mellarini and Dellai signed a pact on the future of the party. Decline and defeats In the 2018 general election the autonomist centre-left was defeated for the first time since 1996. Under the new electoral system, which re-introduced single-seat constituencies also for the Chamber, the centre-right coalition, dominated by the Lega (Lega Nord Trentino) won all such constituencies in Trentino. Dellai was defeated in the Chamber's constituency of Pergine Valsugana, while Mellarini was defeated in the Senate's constituency of Rovereto (by Conzatti, who had switched sides). Consequently Mellarini and Pipinato resigned from secretary and president, respectively. Soon after, the party elected Annalisa Caumo as president and it was decided that the new congress, which will elect the new secretary, will be held in January 2019, after the 2018 provincial election. In the provincial election the party lost much of its support and fell to 4.0%. 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.
