Italy renews its Parliament. On Sunday 4 March, over 50 million Italians will vote to elect 630 members of the Chamber and 315 Senators for their XVIII Parliament. President Sergio Mattarella will choose who should form a new government based on the outcome of the elections. Voting will test the new system provided by the 2017 voting rules, known as Rosatellum bis, for the first time. Overall, the twenty-nine constituencies for the MPs and twenty-one for the new senators, will propose candidates from forty-one party lists and two coalitions, one for the Center-Right and one for the Center-Left. The outgoing government, led by Paolo Gentiloni since 12 December 2016, was the sixty-fourth government of the country, and the third of its XVII parliament following those led by Letta and Renzi.
