HELSINKI—Finland’s prime minister resigned Dec. 3 after a key coalition partner withdrew its support from his five-party government, following a strike at the country’s postal service that spread to the national flag carrier Finnair.
Antti Rinne, who took office in June, has faced heavy criticism in recent days over how he and a fellow Social Democratic minister dealt with a two-week strike of the country’s state-owned postal service Posti in November.
