However, after less than three years from the 2014 electoral landslide, Renzi was forced to resign after the defeat in the constitutional referendum and his foreign affairs minister Paolo Gentiloni was appointed new head of government in December 2016. Moreover, the 2018 general election was characterized by a strong showing of populist parties. The centre-right coalition, led by Matteo Salvini's right-wing League, emerged with a plurality of seats in the Chamber of Deputies and in the Senate while the anti-establishment M5S led by Luigi Di Maio became the party with the largest number of votes; and Renzi's centre-left came only third, with the worst electoral result of its history. However, no political group or party won an outright majority, resulting in a hung parliament. After three months of negotiation, a government was finally formed on 1 June by the M5S and the League, with the M5S-linked independent Giuseppe Conte as Prime Minister and Di Maio and Salvini Deputy Prime Ministers.
