Sanna Marin, 34, becomes world's youngest-serving prime minister

Sanna Marin – a minister of Finland government – will become the youngest Prime Minister in the world when she takes control of the country next week.

The 34-year old transport minister of Finland has been selected by the Social Democrats to lead the nation.

Sanna Marin narrowly won Sunday's vote to replace outgoing leader Antti Rinne, who resigned on Tuesday after losing the confidence of the coalition partner Centre Party over his handling of a postal strike.

Former PM Antti Rinne had headed Finland's centre-left five-party coalition since June, and Marin's appointment is unlikely to lead to significant policy changes by the Social Democrat-led administration.

At 34, Marin also becomes one of the world's youngest state leaders, ahead of Ukraine's prime minister Oleksiy Honcharuk, who is currently 35.

Finland's social democrats, who lead the five-party coalition government, picked on Marin to become the country's PM.

With this, Marin joins the ranks of New Zealand's prime minister, Jacinda Arden and Denmark's Mette Frederiksen. As world leaders under 50.

Meanwhile, the other four parties in Finland are also led by women, three of whom are under 35 years old.
