Barbera took up political office in 1976, when he was elected to the
Chamber of Deputies for the
Italian Communist Party. He would stay member of the Chamber until 1994. When the Communist Party dissolved in 1991, he stayed member of its successor party, the
Democratic Party of the Left. From 1987 to 1992 Barbera served as president of the parliamentary committee on regional questions. On 29 April 1993 Barbera was one of three former Communist Party politicians named in the new
Ciampi Cabinet; the other two were
Vincenzo Visco and
Luigi Berlinguer. Several hours after being officially named in the government, a rupture broke in the coalition over the handling of charges in Parliament against former Prime Minister
Bettino Craxi. The Ministers of the Democratic Party of the Left, to which Barbera belonged, resigned. His replacement,
Paolo Barile, took office on 4 May. On 16 December 2015, the
Italian Parliament elected three candidates to the
Constitutional Court of Italy:
Franco Modugno,
Giulio Prosperetti and Barbera. The election was realized after 31 previous failed attempts. Barbera was the candidate of the
Democratic Party, he obtained 581 votes in favor. He was sworn in five days after his election. == Electoral history ==
