The winner Hungary's election commissioner, Peter Magyar, vowed on Monday to change the constitution in an effort to restore democratic standards, after a landslide victory that he said showed Hungary wanted to be fully anchored in Europe after years of fighting with Brussels.

The super two-thirds majority that Hungary's center-right Tisza party secured in Sunday's election means it will have a free hand to strengthen the rule of law and potentially unlock billions of dollars in European Union funds, but analysts say it will have to actually implement reforms to benefit.

Outgoing nationalist Prime Minister Viktor Orban, in power for 16 years, had pulled Hungary out of the EU mainstream while maintaining warm ties with Russia despite the war in Ukraine. He clashed repeatedly with Brussels over the rule of law and human rights, resulting in the freezing of billions of euros in funds.

Magyar said at a press conference that his government will have many urgent tasks, including amending the constitution to limit the number of terms someone can serve as prime minister to two.

"We will do everything to restore the rule of law, pluralistic democracy and the system of checks and balances," he said.

Magyar said the constitutional amendment would apply to Orban, meaning he could not become prime minister again.

“He had a great opportunity to do great things in the national interest to ensure that Hungary became a developing European country… He did not seize this chance, but abused it,” he said.

Orban's critics say his time in office has seen economic stagnation, international isolation and oligarchs amassing wealth. His supporters say Orban - who has garnered public support from U.S. President Donald Trump, Russia and far-right leaders in Europe - has defended Hungary's sovereignty and traditional values.

Magyar said the election result showed that Hungary had decided to "change the regime" and choose a pro-European path.

"The Hungarian people yesterday, exactly 23 years after the referendum on our EU membership, confirmed Hungary's place in Europe," he said.

The Tisza leader called on President Tamas Sulyok, who is supported by Orban's Fidesz party, to ensure that the transfer of power takes place as soon as possible. He also reiterated his demand that Sulyok resign.

Hungary's president, a largely ceremonial figure, must convene a new parliament within 30 days of the election. Lawmakers then elect a new prime minister.
