All of these parties are largely like political culture-heritage camps. The actual policy disagreements in Norwegian politics are very minor. Every party is pro-NATO and anti-Russia now – a few are pro-EU but nobody serious suggests joining anymore, so basically all parties would maintain membership in EFTA without the European Union. Progress Party complains about immigration but doesn’t seriously suggest a massive reduction. Bureaucratic requirements for, and restrictions on, immigration are always increasing but the numbers keep increasing. No party serious suggests mass nationalisation of industries or privatising the health service or Statoil. Even the Christian Democrats have largely abandoned opposition to abortion and gay marriage.

These are just flavours driven by the cultural heritage or class status of different sectors of Norwegian society – it does not represent serious ideological diversity.

The person you refer to is Brundtland.
