Although the party usually refuses to position itself within a left–right political spectrum, its president Zmago Jelinčič Plemeniti defined himself as leftist in a 2000 interview for the magazine Mladina. However, the descriptions others have given the party range from left-wing to far-right, including right-wing. According to researchers at the University of Ljubljana, the SNS combines elements of right-wing and left-wing ideology and is not strictly a left-wing, nor a right-wing party, but nevertheless leans closer to the left. The party has been seen espousing more leftist economic policies, while maintaining right-wing social views, which at least partially explains the wide variance in placing it on the political spectrum. The party's ideology has been strongly anti-clerical and has advocated a firm laicist position. The party is also opposed to gay rights. The party opposes the privatisation of state-owned enterprises. The party opposes the introduction of a property tax and supports an increase in the minimum wage. The party has called for a change of the national flag and the coat of arms, feeling that they utilize symbols used by certain World War II paramilitary groups and lack a distinctly Slovenian historical character. The party supports replacing judges' lifetime mandate with an eight-year term. The party is opposed to Slovenia's membership the European Union and NATO. Its leaders have been accused of chauvinist and even racist attitudes towards certain minorities, particularly Slovenia's Romani population. In the early 1990s, the party campaigned against allowing refugees from former Yugoslav republics into the country. The party has since moderated its rhetoric, although its leaders continue to voice strongly anti-Croatian positions. Among other things, Jelinčič has proposed that four disputed villages; Bužini, Mlini, Škodelini and Škrile, be placed within the municipality of Piran for the purpose of participating in Slovenian elections. He also advocates improving relations with Serbia and has opposed the independence of Kosovo. The SNS frequently demands better treatment of Slovene minorities in neighboring countries.
Party foundations and leadership
The party was founded on 17 March 1991 by Zmago Jelinčič Plemeniti, who remains the party's leader. The traditional 19th centuryKozler map of United Slovenia is one of the official party symbols. In 1993, dissenting factions broke from the party and formed the Slovenian National Right and the National Party of Labor. Many of the dissenting members were supporters of Slovene Home Guard and objected to Jelinčič's support of the Slovene Partisans. Another split occurred in 2008, when several Slovenian National Party MPs left the party and formed the party Lipa. These splits did not seriously affect the party's structure, even though the ideologies of both SNS MPs and the party's membership tend to sometimes differ from Jelinčič's stands. In July 2020, the party reached a cooperation agreement with the 14th Government of Slovenia.
