The new 'first secretary" will chair meetings in lieu of leader Kim Jong Un (File) Seoul, South Korea: North Korea's ruling party has amended its rules to create a de facto second-in-command under leader Kim Jong Un as he looks to revamp domestic politics, South Korea's Yonhap news agency said on Tuesday. Citing an unidentified source familiar with North Korea, the agency said the holder of the new post of "first secretary" would chair meetings on behalf of Kim Jong Un. Kim cemented his power at a congress of the Workers' Party of Korea (WPK) in January, where he was elected its general secretary, taking a title last held by his late father, Kim Jong Il.
