Finland has sworn in the world’s youngest sitting head of government. The Nordic country’s parliament confirmed 34-year-old Sanna Marin as its prime minister on Tuesday. Marin, a Social Democrat, is set to lead a five-party coalition government. The other four parties also are led by women. All but one of the party leaders are under the age of 35. Finland’s government resigned last week after the Centre Party said it had lost confidence in Social Democrat Prime Minister Antti Rinne. Marin takes over during nationwide labor unrest and strikes. Marin is known for her support of climate and environmental issues. She was raised in a so-called “rainbow family,” headed by two women. She has told Finnish media about growing up in what she described as “modest” conditions. She has also spoken of past struggles to find her way in life, and the fulfillment she has found in politics.
