Pyongyang, October 17 (KCNA) -- Son Hak Gyu, representative of the opposition Democratic Party of south Korea, vowed Friday to expose the inside story of the corruption of the chief executive and his relatives, according to the south Korean KBS.

He accused the authorities of Socho District Office in Seoul of illegally funding the building of a tennis court in Naegok-dong out of its budget.

Rumor has it that the court has something to do with the chief executive, he said, calling for probing the truth through the investigation into the state administration.
