Jens Stoltenberg, a former prime minister of Norway, has been appointed to succeed Anders Fogh Rasmussen as NATO secretary general starting Oct. 1.
Rasmussen’s term will end on that date after five years and two months in the position, NATO announced Friday.
Stoltenberg will also assume the chairman role for the alliance’s North Atlantic Council.
He served as Norway’s prime minister between 2000 and 2001 and led the country again in a second stint from 2005 to October 2013.
His international assignments have included chairman of the United Nations’ high-level system-wide coherence panel and the organization’s climate change financing advisory group.
Stoltenberg currently leads the Norwegian Labour Party and also serves as the UN special representative on climate change.
