Allern 2010, p. 26: "The Norwegian Progress Party is...traditionally characterised as a borderline case of the extreme or radical right (Ignazi 1992: 13–15; Kitschelt 1995: 121; Ignazi 2003: 157), and Mudde (2007:19) characterises FrP as a non-radical populist party"; see also: p.212.

Widfeldt 2014, p. 83: "The academic literature is not unanimous in classifying FrP as an extreme right party. Cas Mudde, in his book from 2007, argues that FrP does not belong to the populist radical right family... Instead, he classifies FrP as a "neoliberal populist party". Other writers, however, do place FrP in the same category...even if they in some cases do so with qualifications"; see also: p.16. Widfeldt, Anders (2014). Extreme Right in Scandinavia. Routledge.

"Forskere: Frp er høyrepopulistisk", Verdens Gang (NTB), 14.09.2013. "- Ja, de er høyrepopulister. Men sammenlignet med andre slike partier i Europa er de en moderat utgave og har sterkere innslag av liberalkonservative strømninger, sier Jupskås." ("Yes, they are right-wing populists. But compared to similar parties in Europe, they are a moderate version, and have stronger elements of liberal-conservative currents, Jupskås (Anders Ravik Jupskås, lecturer Department of Political Science, University of Oslo) says.")
