Preliminary results in Italy's general election suggest the country faces the prospect of a hung parliament.
They show a centre-right coalition winning about 37% of the parliamentary vote and the 5-Star Movement getting about 31%, with the centre-left coalition far behind with 23%.
With no faction winning a clear majority the results confirm that negotiations to form a government that can win a confidence vote in Parliament will likely be long and fraught.
The partial results - released by Italy's interior ministry - show the right-wing, anti-immigrant and eurosceptic Northern League party of Matteo Salvini surpassing the establishment Forza Italia party of former prime minister Silvio Berlusconi.
The Northern League captured around 18%, while Forza Italia had less than 14%.
"Ungovernable Italy" was how Italian daily newspaper La Stampa headlined its election summary.
Political analyst Lorenzo Codogno of London-based LC Macro Advisors commented: "Financial markets are likely to take these figures negatively."
He added that a hung Parliament would make it "extremely difficult for a narrow mainstream coalition to have the numbers to govern".
How the seats finally are sorted out could determine if Italy is swept up in the eurosceptic and far-right sentiment that has emerged in much of Europe.
The run up to the election saw clashes between anti-fascist protestors and supporters of far-right parties.
ITV News recorded customers at one Milan restaurant openly performing fascist salutes while listening to Mussolini-era marching songs.
In the last four years, 600,000 economic migrants and refugees have arrived in Italy, fuelling anti-immigrant sentiment which has led to the rise of populist parties.
In just a few short years, the Northern League has gone from a small party in the north of Italy to a national force which could soon be part of the most right-wing Italian government since the Second World War.
A few weeks ago a candidate who once stood for the same party shot six immigrants in the central Italian town of Macerata, and police later found Hitler's writings in his apartment.
