360 Association (Associazione 360) is a centrist faction within the Democratic Party (PD), a political party in Italy. It is led by Enrico Letta and that is why its members are often called Lettiani. The association was founded during the summer of 2007 in support of the candidacy of Enrico Letta, a former Christian Democrat, to the leadership of the newly formed party and represents a centrist position within the party, as he has good relations with almost all the factions of the party, including Veltroniani, Rutelliani, Dalemiani and the Reformists and Democrats, Ulivists, of which he has been considered a member, and The Populars, of which he is currently member.
