Italys President Sergio Mattarella approved the countrys far-right and anti-establishment parties nominee for prime minister on Wednesday, putting the nation on track to have one of the most populist and radical administrations in all of Europe.

The far-right Lega and anti-establishment Five Star parties chose law professor Giuseppe Conte as their consensus pick for Italys next prime minister, despite his lack of governing experience. Mattarella giving Conte a mandate to form Italys next government clears one of the final hurdles for the two parties before they can begin to run the country.

Both Lega and Five Star hold anti-migrant, anti-European Union views and look to bring the country closer to Russia through lifting economic sanctions against the Kremlin. The new populist government sets Italy up for a clash with the EU and brings more uncertainty for the countrys already fractured politics.

The two non-traditional parties decided to band together after Italys election in March left no outright winner and resulted in months of negotiations to form a governing coalition. Italians rejected the countrys once-powerful establishment parties in the vote, leaving Lega and Five Star to fill the void.

The traditional Italian party system disappeared many elections ago, said Sheri Berman, a professor of politics at Barnard College. What youre seeing now is the detritus of that which is a mess.

A Lega and Five Star coalition was widely seen as a worst case scenario for the EU after Italys vote, as both parties hold a longstanding opposition to the bloc. HuffPost Italia obtained an early draft of the coalitions governing contract in which the two parties hoped to renegotiate EU treaties and identify ways they could potentially opt out of the euro.
