34-year-old Sanna Marin, a Finnish lawmaker, will become the world's youngest sitting prime minister when she ascends to the position in her country this week.
The Social Democratic Party, the ruling party of Finland, voted by a narrow margin on Sunday to affirm Marin to the post. The party with the most seats in Finland's parliament retains the right to appoint the prime minister of the country.
Marin posted a Tweet in Finnish on Monday that read, "Thank you for all the congratulations!"
Marin has rapidly risen through the ranks of the Finnish politics, serving as her party's vice chairwoman as well as the country's minster for transport and communications. She received the prime minister post after the former prime minister, Antti Rinne, stepped down last week.
