Fassina is an Italian economist and was a former member of left-wing, pro-Europeanist Democratic Party (PD).

He later assumed more critical views on the European Union (UE), formed Future to the Left (FaS) and was a founding member of Italian Left (SI) in 2015.

[7] In September 2019, PeC supported the formation of the second government of Giuseppe Conte, composed by the Five Star Movement, PD and LeU.
