The Progress Party currently regards itself to be a "liberal people's party", and its ideology to be classical liberalism[33] or conservative liberalism.[113] The party identifies itself in the preamble of its platform as a liberal (liberalistisk; "liberal, libertarian")[114] party, built on Norwegian and Western traditions and cultural heritage, with a basis in a Christian understanding of life and humanist values.[115] Its main declared goal is a strong reduction in taxes and government intervention.[115] The party is today considered to be conservative liberal,[2] but has sometimes been described as populist.[116] It has also been described as Europe’s most moderate populist party.[117] While more fundamental libertarianism was earlier a component of its ideology, this has in practice gradually more or less vanished from the party.[118] As of the late 2000s, the party has also been influenced by Thatcherism, particularly with Siv Jensen becoming party leader.[119]
