On Monday, Rome woke up to the unpalatable prospect of a hung parliament. The incumbent Democratic Party (PD) suffered a devastating defeat, from 40.8 per cent in 2014 European elections to 18.7 per cent now, while populist forces made sweeping gains in the general election. The anti-establishment Five Star Movement (M5S), which had already affirmed itself in 2013 as Italy鈥檚 single-largest party, further strengthened its position, earning more than 32 per cent of the vote.

Within the centre-right coalition, anti-immigration Northern League outstripped Silvio Berlusconi鈥檚 Forza Italia, winning more than 17 per of the vote in an unprecedented feat for a party that earned little more than 4 per cent in the previous general election. And yet, neither M5S nor the centre-right coalition can form a government unless they strike a deal with other political forces.

President of the Republic Sergio Mattarella must start consultations aimed at averting a political stalemate and facilitating the formation of a cross-party coalition. In his first public appearance after the election, M5S Leader Luigi Di Maio declared that the Movement is open to dialogue with all political forces, talking and acting already as the next prime minister. But the centre-right coalition appears to be holding together, with Northern League Leader Matteo Salvini saying that, 鈥渁s prime minister,鈥 he intends to work with the centre-right coalition and is not open to 鈥渂izarre alliances.鈥 Therefore, political gridlock possibly followed by a new election cannot be excluded at this point.

This result comes at the end of a highly divisive and polarizing electoral campaign that hinged on national security and anti-immigration policies, rather than on Italy鈥檚 stagnating economy and worryingly high youth-unemployment rate. To make matters worse, the campaign was characterized by episodes of political violence, reminiscent of the wave of both left- and right-wing domestic terrorism the country experienced between the 1960s and the 1970s.

Whatever happens in the next few weeks, Italy鈥檚 populist parties will be forced to figure out how to deliver on their extremely ambitious electoral promises.

Italy is no stranger to populism 鈥 in fact, Italy has historically been a very strong and enduring market for populists, as epitomized by the Italian electorate鈥檚 long-lasting fascination with Mr. Berlusconi, who rose to the top of Italian politics almost a quarter of a century before a bombastic tycoon became the 45th President of the United States.
