Voters in Hungary headed to the polls on Sunday in parliamentary elections that could pose the most significant threat yet to Prime Minister Viktor Orban after 16 years in power.

Polling stations opened at 6 a.m. local time and are scheduled to close at 7 p.m., with all 199 seats in parliament up for election.

Recent opinion surveys suggest Orban’s ruling Fidesz party is trailing the opposition Tisza party, led by Peter Magyar, by between 7 and 9 percentage points. Tisza has been polling at roughly 38% to 41%, signaling a competitive race.

Orban, a nationalist and outspoken Eurosceptic, has framed the election as a choice between “war and peace.” His campaign has warned that a victory for Magyar could draw Hungary into the Russia-Ukraine conflict—an accusation the opposition leader has strongly rejected.

“I am here to win,” Orban told reporters after casting his vote at a polling station in Budapest.

The election comes amid growing public frustration over economic challenges, including stagnant growth and rising living costs. Critics have also pointed to concerns about wealth accumulation among business figures with close ties to the government.

“I am very excited but also very scared,” said Kriszta Tokes, a 24-year-old vendor in Budapest, speaking to Reuters. “I know that my future depends on this,” she added, noting she may consider leaving the country if Orban remains in power.

Magyar, a 45-year-old former government insider, has emerged as a prominent challenger in just two years, capitalizing on voter dissatisfaction despite an electoral system widely seen as favoring the ruling party.
