Italy will no longer be "Europe's refugee camp," the country's newly installed interior minister, Matteo Salvini, said on Monday.

Salvini, head of the right-wing League and a deputy prime minister in the eurosceptic coalition, has made curbing immigration a clarion call of his party, whose popularity is rising fast in opinion polls.

The League says that the vast majority of migrants in Italy have no right to refugee status, that Italy cannot afford to help them, and that by accepting low pay they worsen the working conditions of Italians.

ROME — Italy will no longer be "Europe's refugee camp," the country's newly installed interior minister, Matteo Salvini, said on Monday as he promised tough action to reduce migrant arrivals and send back those who have already come.

Salvini, head of the right-wing League and a deputy prime minister in the eurosceptic coalition, has made curbing immigration a clarion call of his party, whose popularity is rising fast in opinion polls.

Two days after the government was sworn in on Friday, Salvini headed for Sicily, the main port of call for more than 600,000 migrants who have arrived on Italy's shores from North Africa since 2014.

"The party is over" for migrants in Italy, he said before visiting a so-called hotspot, or reception center, in the port of Pozzallo, where boat-borne arrivals are registered, photo-identified, and fingerprinted.

The League says that the vast majority of migrants in Italy have no right to refugee status, that Italy cannot afford to help them, and that by accepting low pay they worsen the working conditions of Italians.

Salvini kept up the pressure on Monday, saying in a radio interview that Italy "can't be transformed into a refugee camp" and vowing to lobby Italy's partners to obtain more EU assistance to handle the problem.

"It's clear and obvious that Italy has been abandoned — now we have to see facts," Salvini said when asked about comments from German Chancellor Angela Merkel that Europe needs a new approach to immigration.

Salvini, who wants to open a migrant detention and deportation center in every Italian region, later tweeted: "Either Europe gives us a hand in making our country secure, or we will choose other methods."

Italy has become the main route into Europe for economic migrants and asylum seekers, with hundreds of thousands making the perilous crossing from North Africa each year and thousands dying at sea. The other main route, from Turkey to Greece, was largely shut down after more than 1 million people arrived in 2015.

After at least 48 migrants were killed over the weekend when their boat sank off Tunisia's coast, Salvini said there was no reason for people to be fleeing Tunisia, which he called "a free and democratic country."

An opinion poll by the Ipsos agency published on Saturday in the daily newspaper Corriere della Sera showed support for the League had risen to 28.5% from 17% at the March 4 election.

It now stands just 1.6 points behind its coalition partner, the more left-leaning Five-Star Movement, whose support has slipped slightly since it took 32.7% at the election.

Western Europe's first antiestablishment government, which faces its first confidence vote in the upper house senate on Tuesday, seems determined to hit the ground running.

Luigi Di Maio, a deputy prime minister and labor and industry minister who leads the Five-Star Movement, pledged on Saturday to overhaul the signature labor legislation, known as the Jobs Act, of the previous center-left government.

Italian markets, which sold off heavily early last week on fears of a repeat election, continued to recover on Monday.

The gap between the yield on Italy's benchmark bonds and their safer German equivalent narrowed to its tightest in a week, while Italy's blue-chip share index recovered from early losses and was up 0.4%.
