Bucharest, Romania - Romania's interim president appointed a new prime minister on Tuesday, the day after Marcel Ciolacu resigned after the league candidate failed to rerun the runoff in the presidential election.

Ilie Bolojan signed a decree requiring Catalin Predoiu, the National Liberal Party, to be appointed to the Interior Minister, to take charge of the government until a new government can be formed. Temporary positions can be held for up to 45 days, during which time their administrative power is limited.

The league candidate Crin Antonescu ranked third in the first round of presidential votes on Sunday, well behind top champions Hand nationalist George Simion and pro-Western reformer Bucharest Mayor Nicusor Dan, this time reorganization.

After the vote on Sunday, the 56-year-old veteran politician Predoiu said he voted for the president, "will ensure balance, cooperation and dialogue in political life", saying it was "an important moment for the entire country."

Romania lasted for months after the Supreme Court announced the campaign after Moscow denied allegations of election violations and Russian intervention. An unprecedented decision has put Romania in its worst political crisis in decades.

Sunday’s vote highlighted a strong anti-establishment sentiment among voters and showed that power has shifted from traditional mainstream parties. It also updates political uncertainty among EU and NATO member states.

"Instead of letting the future president replace me, he decided to resign," Ciolacu, who ranked third in the presidential election that was invalid last year, told reporters outside his Social Democratic headquarters (PSD) on Monday.

He added that the coalition was formed in December last year after the election was defeated to ordinary candidates who won the presidency. After Sunday's results, he said the league is now "lack of any credibility". It consists of the left-wing PSD, the center-right national liberal party, the small Hungarian UDMR party and the minority.

Sunday’s vote was the second time in post-communist history in Romania, including the innocence election cycle, where the PSD party had no candidates in the second round of the presidential race.

Like many EU countries, Romania has high anti-establishment sentiment driven by high inflation, massive budget deficits and slow economies. Observers say the discomfort has gained support for nationalists and far-right figures, such as Calin Georgescu, who won the first round in the cancelled presidential election. He is under investigation and is banned from replay.

Simion, the 38-year-old leader in the Sunday voting and leader of the Romanian Solidarity Alliance, will face Denmark in the May 18 runoff that could reshape the country's geopolitical direction.

In 2019, Simion established the AUR party, which announced its representation in the 2020 parliamentary elections, "family, nation, faith and freedom" and stood out in the 2020 parliamentary elections. Since then, it has become the second largest party in the Romanian legislature.

Dan, a 55-year-old mathematician and former anti-corruption activist, founded the Save Romania Union Party in 2016 and ran on a Pro-eu platform. He told the media earlier Monday that “a second difficult second round against the isolationist candidate.”
