What is "leftdem"

LeftDem (SinistraDem) is a social-democratic faction within the Democratic Party (PD), a political party in Italy.

The faction was launched by Gianni Cuperlo, who lost the 2013 leadership election to Matteo Renzi, in June 2014, as an association open to Democrats, independents and members of other parties. In the following October the faction's assembly saw the participation, among others, of Sergio Cofferati and Stefano Fassina.
