Finland's parliament has approved the nomination 34-year-old Social Democrat Sanna Marin as the world's youngest serving prime minister.

Out of the parliament's 200 members, 99 voted in favour and 70 against Ms Marin's nomination as the country's new prime minister.

Thirty deputies were absent.

Finland's government resigned last week after the Centre Party said it had lost confidence in Social Democrat Prime Minister Antti Rinne over his handling of a postal strike.
