Hungary's election authorities say the upstart opposition Tisza party is certain to win more than two thirds of parliamentary seats in Sunday's election, defeating Prime Minister Viktor Orban's ruling party.
The pro-European Tisza's victory is expected to lead to a change of government in Hungary for the first time in 16 years.
With over 89 percent of the vote counted, Tisza gained 138 of 199 seats, while Orban's Fidesz party won 54.
Orban is known for his pro-Russian stance, and has opposed the European Union's assistance for Ukraine in its fight against Russia's invasion. He also advocates a policy of putting Hungary first, and has maintained favorable relations with US President Donald Trump.
