The 2004 European election was the sixth election to the European Parliament. As Slovenia had only joined the European Union earlier that month, it was the first European election held in that state. The election took place on 13 June 2004. The biggest surprise was the victory of the New Slovenia party over the Liberal Democracy of Slovenia and the defeat of the Slovene People's Party, which did not win a seat. The parties on the right of centre that form the opposition in the Slovenian national parliament won this election.
The 2009 European election was the seventh election to the European Parliament and the second for Slovenia. The number of seats was increased to eight.
