It seems nowadays a lot of politicians are effectively groomed for such a career from their teens when they see early success in some youth organisation. Sometimes a part of that process is to acquire some kind of academic background for them, justly earned or not.

Ed. I checked and both Sandra Borch and Ingvild Kjerkol seem to have been active in party politics from an early age. Exactly fits the mold of groomed career politicians.

Plagiarism is a form of lying. Politicians are liars. No surprise that plagiarism in political circles is rampant. Quite often such MS and PhD thesis are written by "ghost writers" for a fee. Politicians are busy advancing their political careers and a degree is needed just for its title not its content. PhD as a modern form of aristocratic title :-)
