Russian foreign electoral intervention

Parliamentary elections were held in Hungary on 12 April 2026 to elect all 199 members of the National Assembly. It was the 10th parliamentary election and the highest-turnout election since Hungary's transition to democracy in 1990. The opposition Tisza Party, led by MEP and former Fidesz member Péter Magyar, obtained a landslide victory, defeating the incumbent Fidesz–KDNP government of Prime Minister Viktor Orbán, and ending the 16-year Orbán era. In the first election since 2006 not won by Fidesz–KDNP, Tisza Party won a two-thirds supermajority, which is the legislative threshold to amend the Fundamental Law of Hungary. In the process, it won both the largest number of votes and the largest percentage of seats that a Hungarian political party has ever won in a free election.
