A 34-year-old transport minister and parliamentarian has been named as Finland’s prime minister and its third female government leader. Finland’s ruling Social Democratic Party council voted 32-29 on Sunday to name Sanna Marin over rival Antti Lindtman to take over the government’s top post from incumbent Antti Rinne. Having emerged as Finland’s largest party in the April election, the Social Democrats can appoint one of their own to the post of prime minister in the Nordic nation of 5.5 million. Ms Marin has been the party's vice chairwoman, a parliamentarian since 2015 and served as the minister for transport and communications until this week. According to Finland's biggest newspaper, <em>Helsingin Sanomat</em>, and the <em>Ilta-Sanomat</em> tabloid, Ms Marin will become the world's youngest sitting prime minister. Finland holds the European Union’s rotating presidency until the end of this year. Politicians are likely to approve the appointment of Ms Marin and her new government quickly so she can represent Finland at the EU leaders’ summit in Brussels later this week. Mr Rinne stepped down after a key coalition partner, the Centre Party, withdrew its support saying there was a lack of trust. The Centre Party also criticised Mr Rinne’s leadership skills prior to a two-week strike by the country’s state-owned postal service Posti in November that spread to other sectors, including the airline Finnair. Mr Rinne’s decision prompted the resignation of a coalition of the Social Democrats and the Centre Party and three junior partners: the Greens, the Left Alliance and the Swedish People’s Party of Finland. On Sunday, Social Democrats and the four other coalition parties said they are committed to the government programme agreed upon after the April election and will continue in Ms Marin’s new government. Social Democrats said Sunday they’re seeking to have Mr Rinne, a former trade union leader, become the parliament’s vice speaker. He also plans to stay on as the Social Democrats’ chairman until next summer.
