North Korean leader Kim Jong Un convened an unprecedented conference aimed at strengthening the ruling Workers' Party of Korea's (WPK) "monolithic" leadership across society, state media reported on Thursday.

The conference was the first of its kind and involved "realizing the organizational and ideological consolidation of the Party ranks in every way" and enhancing the party's leadership role, state-run news agency KCNA said.

The event focused on the "Party Life Guidance" (PLG) sections, which are powerful organizations that monitor and police loyalty of officials and members across the country.
