The longest-serving head of government in European Union
Viktor Orban,58, is already the longest-serving head of government in the European Union, who was challenged by a coalition of six opposition parties.
With 94 per cent of voting, Orban was on 53 per cent and his opposition on 35 per cent.
For the first time more than 200 international observers, as well as thousands of domestic volunteers from both sides watched the election.
Oppositions admits defeat
Peter Marki-Zay, the conservative leader of the opposition party addressed the supporters and admitted defeat.
Russian President Vladimir Putin congratulated Hungarian Prime Minister Viktor Orban after his party won a fourth term in office and said he hoped to further build ties, the Kremlin said.
The 69-year-old Russian leader has been increasingly isolated internationally after he sent troops to pro-Western Ukraine on February 24.
The nationalist Hungarian prime minister has been one of his rare allies in Europe and in NATO.
Official results from Hungary's general election on Sunday showed Orban's Fidesz party had won a fourth term in office by a much greater margin than pre-election polls had suggested, after a campaign overshadowed by the Ukraine conflict.
Orban on ‘Russia-Ukraine conflict’
Diplomatically, Orban fell into line with EU support for Kyiv despite his longstanding closeness to Putin.
But at home, Orban has struck a neutral and even anti-Ukrainian tone at times, refusing to let weapons for Ukraine cross Hungarian territory.
Ukrainian President Volodymyr Zelensky has singled Orban out for criticism over his reticence to take a tougher stance against Russia.
Orban's administration has presided over repeated confrontations with the European Union, including over the neutering of the press and judiciary, and measures targeting the LGBTQ community - also the subject of a vote on Sunday.
