BUDAPEST, Hungary — Hungarian Prime Minister Viktor Orbán conceded defeat on Sunday after what he called a ″painful″ election result, ending 16 years in power for a powerful figure in the far-right movement allied with U.S. President Donald Trump and Russian President Vladimir Putin.

Partial official results show opposition leader Peter Magyar’s party dominating the vote, in a bombshell election result with repercussions around Europe and beyond. ‘’Thank you, Hungary!” Magyar posted on X, as thousands of his supporters thronged the banks of the Danube in Budapest.

Across town, Orban told his followers that “I congratulated the victorious party.”

“We are going to serve the Hungarian nation and our homeland from opposition as well,” he said.

With 60% of the vote counted, Magyar’s Tisza party had more than 52% support to 38% for Orbán’s governing Fidesz party. That proportion will change as more votes are counted.

It’s a major blow for Orbán, the European Union’s longest-serving leader and one of its biggest antagonists, who has traveled a long road from his early days as a liberal, anti-Soviet firebrand to the Russia-friendly nationalist admired today by the global far-right.

The parties of both Orbán and Magyar said they had received reports of electoral violations, suggesting some results could be disputed by both sides.

Turnout by 6:30 p.m. was over 77%, according to the National Election Office, a record number in any election in Hungary’s post-Communist history.

“I’m asking our supporters and all Hungarians: Let’s stay peaceful, cheerful, and if the results confirm our expectations, let’s throw a big, Hungarian carnival,” Magyar said.

Orbán’s chief of staff, Gergely Gulyás, said the record high turnout showed that “Hungarian democracy is extremely strong.”

Orbán has repeatedly frustrated EU efforts to support Ukraine in its war against Russia’s full-scale invasion, while cultivating close ties to President Vladimir Putin and refusing to end Hungary’s dependence on Russian fossil fuel imports.

Recent revelations have shown a top member of his government frequently shared the contents of EU discussions with Moscow, raising accusations that Hungary was acting on Russia’s behalf within the bloc.

The election was closely watched in countries around Europe and beyond, which is a testament to the outsize role Orbán occupies in far-right populist politics worldwide.

Members of Trump’s “Make America Great Again” movement are among those who see Orbán’s government and his Fidesz political party as shining examples of conservative, anti-globalist politics in action, while he is reviled by advocates of liberal democracy and the rule of law.

After casting his vote, Magyar told reporters that the election was “a choice between East or West, propaganda or honest public discourse, corruption or clean public life.”

Casting his ballot in Budapest, Marcell Mehringer, 21, said he was voting “primarily so that Hungary will finally be a so-called European country, and so that young people, and really everyone, will do their fundamental civic duty to unite this nation a bit and to break down these boundaries borne of hatred.”

During his 16 years as prime minister, Orbán has launched harsh crackdowns on minority rights and media freedoms, subverted many of Hungary’s institutions and been accused of siphoning large sums of money into the coffers of his allied business elite, an allegation he denies.

He also has heavily strained Hungary’s relationship with the EU. Although Hungary is one of the smaller EU countries, with a population of 9.5 million, Orbán has repeatedly used his veto to block decisions that require unanimity.

Most recently, he blocked a 90-billion euro ($104 billion) EU loan to Ukraine, prompting his partners to accuse him of hijacking the critical aid.

Magyar rapidly rose to become Orbán’s most serious challenger. The 45-year-old leader of the center-right Tisza party, which led in independent polls, campaigned on issues affecting ordinary voters including Hungary’s faltering public health care and transportation sectors and what he describes as rampant government corruption.

A former insider within Orbán’s Fidesz, Magyar broke with the party in 2024 and quickly formed Tisza. Since then, he has toured Hungary relentlessly, holding rallies in settlements big and small in a campaign blitz that recently had him visiting up to six towns daily.

In an interview with The Associated Press earlier this month, Magyar said the election will be a “referendum” on whether Hungary continues on its drift toward Russia under Orbán, or can retake its place among the democratic societies of Europe.

Tisza won 30% of the vote in European Parliament elections in 2024, and Magyar took a seat as an EU lawmaker. Tisza is a member of the European People’s Party, the mainstream, center-right political family with leaders governing 12 of the EU’s 27 nations.

Magyar and Tisza face a tough fight. Orbán’s control of Hungary’s public media, which he has transformed into a mouthpiece for his party, and vast swaths of the private media market give him an advantage in spreading his message.

The unilateral transformation of Hungary’s electoral system and gerrymandering of its 106 voting districts by Fidesz also will require Tisza to gain an estimated 5% more votes than Orbán’s party to achieve a simple majority.

Additionally, hundreds of thousands of ethnic Hungarians in neighboring countries had the right to vote in Hungarian elections and traditionally have voted overwhelmingly for Orbán’s party.

Fidesz and Tisza both have launched platforms for reporting irregularities, accusing their opponents of planning to commit election abuses.

Russian secret services have plotted to interfere and tip the election in Orbán’s favor, according to numerous media reports including by The Washington Post. The prime minister, however, has accused neighboring Ukraine, as well as Hungary’s allies in the EU, of seeking to interfere in the vote to install a “pro-Ukraine” government.

Such accusations are part of why many in the EU see Orbán as a danger to the bloc’s future.

But across the Atlantic, Trump and his MAGA movement are all-in for another Orbán term. Trump has repeatedly endorsed the Hungarian leader and U.S. Vice President JD Vance made a two-day visit to Hungary last week meant to help push Orbán over the finish line.
