It seems highly unusual that Katrin Jakobsdottir (Prime Minister of Iceland) is able to emerge from the last election with third-most seats in Parliament and still remain as leader of government.
How could this happen when both of her coalition partners have more seats than her party? The parliamentary arithmetic just doesn't make sense.
Is this just something Icelandic people do culturally? Or is there a more calculative reasons that led to this outcome?
