In the 2013 general election the LD externally supported Mario Monti's Civic Choice and, after the election, Melchiorre returned to her job as magistrate and, having consequently resigned from party president, she was replaced by Tanoni. In the 2016 constitutional referendum the party was part of the "yes" camp, that was soundly defeated, and organised a committee presided by Tiziano Treu, a former minister and senator for Italian Renewal and DL.
