The party's fourth national congress was held in 19–21 April 2007: During local congresses, Fassino and his motion named "For the Democratic Party", backed by most leading members (D'Alema, Pier Luigi Bersani, Antonio Bassolino, etc.), received the support of 75.6% by party members. The left-wing of Fabio Mussi, Cesare Salvi, Fulvia Bandoli and Valdo Spini ("To the Left. For European Socialism") scored 15.0%; this motion was instead opposed to the merger of the DS with DL. A third motion ("For a New, Democratic and Socialist Party"), signed by Gavino Angius, Mauro Zani and originally Giuseppe Caldarola, took 9.3% of the vote: its members (gathered in the new Socialists and Europeans faction) supported the creation of a new party only within the PES, which was opposed by DL.
