The Fidesz–KDNP party alliance has governed Hungary since 2010, altogether obtaining a supermajority in each of the 2010, 2014, 2018, and 2022 national elections.

[4] After the 2006 election, Fidesz and KDNP separately formed parliamentary groups, but they established a caucus alliance in the Hungarian parliament.

[5] Technically Fidesz and KDNP are a coalition, but many consider KDNP to actually be a satellite party of Fidesz,[6][7] since it has been unable to get into the Parliament on its own since 1994 when it barely passed the election threshold of 5% of votes.

[11] On 3 March 2021, the Fidesz left the European People's Party Parliamentary Group, while KDNP remained a member.

[citation needed] In response to the admission of the Tisza Party to the EPP following the 2024 European Parliament election, the KDNP decided to leave the EPP and its parliamentary group on 18 June 2024.
