RIVAL populist leaders fought on Monday for the right to govern Italy after their surge in a general election that has left the country in political limbo.

The anti-immigrant League party and the anti-establishment Five Star Movement (M5S) each claimed Sunday’s vote gave them a mandate to lead the nation of 60 million.

League leader Matteo Salvini said that he had “the right and the duty” to form a government after its surprise success at the heart of a right-wing coalition.

With most ballots counted, the League was leading the dominant right-wing coalition, which won roughly 37 per cent of the vote overall.

The League by itself was closing in on 18 per cent, ahead of former prime minister Silvio Berlusconi’s Forza Italia (Go Italy) party, which collapsed to 14 per cent.

Mr Salvini’s party surged in the polls after promising to shut down Roma camps, deport hundreds of thousands of migrants and tackle what it called “danger” of Islam.

“Italians have chosen to take back control of the country from the insecurity and precariousness put in place by (centre-left Democratic Party leader Matteo) Renzi,” Mr Salvini told a press conference.

But M5S, which won the biggest share of the vote of any single party, claimed it was the winner.

Its leader Luigi Di Maio said it had a “responsibility” to form a government.

However, much depends on M5S, which has drawn support from Italians fed up with traditional parties and a lack of economic opportunity. It won 32 per cent of the vote.

The M5S had previously refused to align itself with other parties, which it considered part of a “corrupt” system.

Mr Di Maio said his party now “feels the responsibility to form a government”.

“We are the winners,” Mr DiMaio told a news conference conference on Monday. He said he was “open to discussion with all political actors”.

According to polling company YouTrend, the M5S was set to gain 231 seats in the lower house Chamber of Deputies and 115 in the upper house Senate.

It could therefore form a majority with either one of the League, Forza Italia and the Democratic Party (PD).

Given its heated rivalry with the PD and Mr Berlusconi, M5S’s most likely ally looked to be the Eurosceptic League.

However Mr Salvini swiftly ruled out the prospect of forming a coalition with the M5S.

“N.O. No, underlined three times,” Mr Salvini told reporters.

Mr Di Maio responded by saying that “we represent the whole nation, from Val D’Aosta to Sicily. The others can’t say that.”

The boost for far-right and populist parties has prompted comparisons to Britain’s vote to leave the European Union and the rise of US President Donald Trump.

Prominent British pro-Brexit figure Nigel Farage congratulated the Five Star Movement, his allies in the European Parliament, “for topping the poll” as by far Italy’s biggest single party.

Resentment at the hundreds of thousands of migrant arrivals in Italy in recent years fired up the campaign, along with frustration about social inequalities.

BERLUSCONI BOMBS AT ELECTION

Silvio Berlusconi, the flamboyant three-time former prime minister, is on the ropes after his electoral flop.

The billionaire, who won his first election in 1994, returned to the limelight at the age of 81 despite a career overshadowed by sex scandals and legal woes.

But he has turned out to be the big loser alongside centre-left Democratic Party leader Matteo Mr Renzi.

The election campaign was marred by clashes between far-right and anti-fascist activists, as well as a racist shooting spree by an extreme right sympathiser last month.

In the event of a stalemate, President Sergio Mattarella will have the key role of choosing a prime ministerial nominee.

Negotiations on forming a majority could take weeks or even months.

“The verdict in Italy is always the same: the country is in constant instability,” said Claudio Tito, columnist.

Financial markets opened lower and were volatile in early trading Monday.
