General elections were held in Italy on 24 and 25 February 2013 to determine the 630 members of the Chamber of Deputies and the 315 elective members of the Senate of the Republic for the 17th Italian Parliament. The centre-left alliance Italy Common Good, led by the Democratic Party (PD), obtained a clear majority of seats in the Chamber of Deputies thanks to a majority bonus that effectively trebled the number of seats assigned to the winning force and narrowly defeated the centre-right alliance of former prime minister Silvio Berlusconi in the popular vote. Close behind, the new anti-establishment Five Star Movement of comedian Beppe Grillo became the third force, well ahead of the centrist coalition of outgoing Prime Minister Mario Monti. In the Senate, no political group or party won an outright majority, resulting in a hung parliament.
In April 2013 a grand coalition was formed, consisting of Italy Common Good, the Berlusconi coalition and the centrists. Berlusconi and his allies withdrew support of the coalition and formed a new Forza Italia six months later, which meant that the PD dominated the government coalition until the 2018 Italian general election.
