Within five years, the country had the world’s first democratically elected female president – Vigdis Finnbogadottir.

It was November 1980, and Vigdis Finnbogadottir, a divorced single mother, had won Iceland's presidency that summer.

If elected, Ms Arnorsdottir would be Iceland's second female president since independence, after Vigdis Finnbogadottir, who was in office between 1980-1996.
