Defunct Identity and Action (Italian: Identità e Azione, IDeA) is a conservative political party in Italy, whose membership stretches from Christian democracy to liberal conservatism.

Two deputies (Vincenzo Piso and Eugenia Roccella) and four senators (Andrea Augello, Luigi Compagna, Carlo Giovanardi and Gaetano Quagliariello) left the NCD because they no longer supported its alliance with the PD.

They were joined by two deputies, Guglielmo Vaccaro (ex-PD, later Unique Italy–IU) and Renata Bueno (South American Union Italian Emigrants–USEI), and several regional politicians, including Davide Bellomo (independent, Apulia), Stefano Casali (Tosi List for Veneto, Veneto), Giovanni Chiodi (independent, former President of Abruzzo) and Vittoriano Solazzi (Marche 2020, Marche).

[9][10][11] In the meantime, the four deputies of IdeA, along with Aniello Formisano of Italy of Values (IdV, a party which had long been part of centre-left coalitions), formed a sub-group, named after the USEI (and, later, "USEI–IdeA"), within the Mixed Group of the Chamber,[12][13] while the party's four senators joined the heterogeneous Great Autonomies and Freedom (GAL) group.

[17][18][19] In December 2017 IdeA was supposed to be a founding member of Us with Italy (NcI), a pro-Silvio Berlusconi centrist electoral list within the centre-right coalition for the 2018 general election, but finally stood out.
