Sanna Marin from Finland is set to become the world’s youngest prime minister at the age of 34.
The transport minister who will be sworn later this week was picked by her Social Democratic party after its leader, Antti Rinne, quit as PM.
She will lead a center-left coalition with four other parties, all headed by women, three of whom are under 35.
Mr. Rinne stepped down after losing the confidence of a coalition member over his handling of a postal strike.
When she takes office, Ms. Marin will be the world’s youngest sitting prime minister. New Zealand PM Jacinda Ardern is 39, while Ukrainian premier Oleksiy Honcharuk is 35.
