Slovenia, the current president of the European Union, will hold a parliamentary election on Sept. 21, President Danilo Turk said on Monday.
The election will pit Prime Minister Janez Jansa's conservatives against the opposition Social Democrats.
Slovenia's EU presidency ends on June 30.
In the last election in October 2004, Jansa's Slovenian Democratic Party (SDS) ended almost 12 years of centre-left rule in the former Yugoslav republic.
Opinion polls show the Social Democrats ahead with 17.7 percent of the vote, followed by the SDS with 16.3 percent.
Slovenia, an Alpine state of 2 million people, joined NATO and the European Union in 2004.
Jansa's popularity has declined since the adoption of the euro in January 2007 as Slovenia's inflation became the highest in the euro zone.
