Back in Parliament
In 2011 the PLI was joined by Enrico Musso, a senator of The People of Freedom (PdL), who was soon appointed deputy secretary of party. Through Musso the party re-joined the NPI.
In November 2011 five disgruntled deputies of the PdL (Roberto Antonione, Giustina Destro, Fabio Gava, Giancarlo Pittelli, who later left, and Luciano Sardelli) joined the party through the Liberals for Italy (LpI). Another former member of the PdL, Angelo Santori, joined the "Liberals for Italy–PLI" sub-group in April 2012.
In March 2012, in the run-up of a congress, Scognamiglio, Biondi and Altissimo proposed Musso as new secretary and De Luca as president. The proposal was not well received by the party's old guard and, not only De Luca was barely re-elected secretary, but Scognamiglio was replaced as president by Enzo Palumbo. In the 2012 municipal election in Genoa, Musso obtained 15.0% of the vote in the first round, as joint NPI candidate, and 40.3% in the run-off, losing to Marco Doria.
In November 2012, a group of deputies (Isabella Bertolini, Gaetano Pecorella, Giorgio Stracquadanio (who had left earlier), Franco Stradella and Roberto Tortoli) broke away from the PdL and formed Free Italy (IL). According to Bertolini, the reason for the split was the attitude of the PdL toward Mario Monti's government, as the party approved all government measures but at the same time bitterly contested them in public communication. In December 2012 the LpI–PLI joined forces with IL and formed a 10-strong sub-group.
In the 2013 general election, the PLI ran with the wording "Liberals for Italy", getting 0.1% of the vote.
In June 2013 Guzzanti re-joined the PLI and was soon elected at the head of the party's national council.
In February 2014 several disillusioned members or former members of the party, including Altissimo, Biondi, Musso and Scognamiglio, plus Edoardo Croci, Giuliano Urbani and Alessandro Ortis, launched The Liberals as an alternative to the PLI, but the new group acted more as think tank than an actual party.
In the run-up of the 2014 European Parliament election the PLI joined the European Choice (SE) list, led by Civic Choice (SC). This decision, strongly supported by De Luca, prompted Guzzanti to leave the party and stand as candidate for the newly-reformed Forza Italia (FI), and eventually De Luca to step down as secretary.
In October 2014, during a party congress, the PLI elected a new leadership, notably including Giancarlo Morandi as secretary, De Luca president and Daniele Toto, a former deputy of the PdL and Future and Freedom (FLI), coordinator. The day after the congress, the PLI mourned the death of Carla Martino, long-time president of the party, later honorary president and sister of FI's leading liberal Antonio Martino. In November Ivan Catalano, a dissident deputy of the Five Star Movement (M5S), joined the PLI, marking its return to Parliament. A few months later, in March 2015, Catalano was expelled from the party for having joined the parliamentary group of SC.
