Slovenia is to hold parliamentary elections on September 21, President Danilo Turk's office said in a statement Monday, dpa reported.
It would be the fifth poll for Slovenia since it split from Yugoslavia in 1991.
Prime Minister Janez Jansa has been plagued by dwindling support throughout his term, but particularly since the introduction of the euro in 2007 fuelled inflation.
Leading the opposition since 2004, the Social Democratic Party hopes to return to power after leading the opposition over the past four years.
Following its remarkably efficient transition from Yugoslav-style Socialism, the small Alpine-Adriatic repubic in 2004 joined the North Atlantic Treaty Organization and the European Union.
Jansa's cabinet has handled the six-month EU presidency in the first half of 2008 without a hitch.
