North Korean leader Kim Jong Un has been elected ruling party general secretary, state media said Monday, taking over the mantle from his late father in a move seen as cementing the role of the Workers’ Party of Korea in the country’s affairs.

Kim was “unanimously” elected to the post to thunderous cheers Sunday, the sixth day of the ongoing party congress, according to the state-run Korean Central News Agency (KCNA).

The rare congress, just the second in four decades, has seen Kim lay out his plans for the country’s economic, military and diplomatic initiatives over the next five years.
