The Federation of Liberal Democrats (Federazione dei Liberaldemocratici, FLD) was a social-liberal party in Italy, based in Milan. Its leader and founder was Marco Marsili, a former member of the Federation of Greens, party he left over disagreements with leader Alfonso Pecoraro Scanio.
The party was founded in October 2003 by Marsili as a citizens' list named Liberaldemocratici – Lista per Milano Città Metropolitana. After having formed an alliance with the Pact of Liberal Democrats, FLD joined Italy of Values for the 2006 general election. Although Marsili was a top-list candidate in Milan, he failed to get elected. In May 2006 FLD formed a provisional alliance with The Italian Socialists, and finally took part of the foundation of the Citizens' Political Movement in September 2007. Marsili was suddenly appointed by Fernando Rossi national coordinator of the new party.
