Viktor Orban, Hungary's staunchly anti-migrant Prime Minister, was re-elected after his right-wing Fidesz Party was projected to win a supermajority of seats in Hungary's Parliament.
The resounding victory will likely permit Orban's Government to continue with democratic backsliding.
Orban's party was expected to win 133 of 199 seats in Parliament, according to the first results from Hungary's national election website, with more than 90 per cent of votes tallied. That barely gives him the two-thirds majority he needs to rewrite the constitution as he sees fit.
The largest opposition group was projected to be the far-right Jobbik party, which shares much of Fidesz's anti-immigrant platform and was expected to claim 26 seats.
The vote - easily the most consequential since Hungary's post-communist transition - was widely seen as a reflection on the state of democracy and the rule of law in a European Union member state that in recent years has been sliding toward autocracy.
