The results represent a 10% drop in support for the nationalist Fidesz party. Opposition leader Peter Magyar called the vote "the beginning of the end" for Hungarian Prime Minister Viktor Orban's grip on power.
Fidesz and its politicians reportedly spent 2 million euros in five months, promoting anti-Western narratives. The party paid for six out of 10 most promoted videos.
The wave of discontent arose after it was revealed that President Katalin Novak, who resigned on Feb. 10, pardoned a man convicted of covering up widespread sex abuse at a government-run children's home.
The BBC and other outlets have characterized the ongoing scandal as Hungarian Prime Minister Viktor Orban's "biggest challenge in 14 years of uninterrupted Fidesz rule."
