Chairman Kim Jong Il clarified for the first time in history an original idea that a revolutionary party of the working class is, in essence, the party of the leader.
It implies that a revolutionary party is a political organization that is solidly united organizationally and ideologically with the leader as a centre and materializes the leader’s ideas and leadership.
A revolutionary party becomes the party of the leader as it is founded, strengthened and developed by the leader.
The definition that a revolutionary party of the working class is the party of the leader gives a new explanation to the essence of the party and constitutes a starting point of the Juche-oriented revolutionary party building theory put forward by Chairman Kim Jong Il.
