HELSINKI -- Sanna Marin is expected to be tapped as Finland's prime minister Tuesday, becoming the world's youngest head of government at the head of a five-party, center-left coalition.
The Nordic country's Parliament, the 200-seat Eduskunta, is set to approve Marin, whose government will have a comfortable majority of 117 seats, later Tuesday.
Marin who is the number two in the Social Democratic Party, takes over from incumbent Antti Rinne, who stepped down a week ago after a key coalition partner, the Center Party, withdrew its support, citing lack of trust.
Rinne has said he plans to continue as party leader until a party congress next summer.
Tuesday's appointment will allow Marin to represent Finland at the Dec. 12-13 EU leaders’ summit in Brussels. Finland currently holds the European Union's rotating presidency until the end of the year.
The four other parties in the coalition are all headed by women — three of whom are in their early 30s.
