More than 25,000 people including members of civic and social organizations, university students, citizens and overseas Koreans took part in the rally.

Speakers at the rally said the last "presidential election" was illegal as it was affected by corrupt practices of the Intelligence Service.

Nevertheless, the ruling quarters disturb in every way the investigation into the IS's interference in the election now under way by the protests and demand of people of different social standings, they said, and went on:

Nam Jae Jun, director of the IS, refused to appear in the special committee of the "National Assembly" for the investigation, an action of disregarding the people.

Media have not reported the news of the people's movement for making public the declaration on the situation denouncing the illegality of the IS as well as the news of the revelation of video footage of the place where the IS conducted illegal cyber terror during the "presidential election".
