Woman, a full investigation of the "civil war criminal" banner..."Legal response is inevitable."

The People's Power has launched a full investigation into the banner, which describes the ruling party lawmaker as a "civil war accomplice."

Floor spokesman Park Soo-min met with reporters and said, "It is inevitable to respond because it is illegal to announce an issue that has not been legally confirmed."

He then explained that he would complete the full investigation within this week and take legal action centered on the party's legal advisory committee.

Earlier, the NEC allowed the posting of a banner that said "an accomplice in a civil war" targeting a ruling party lawmaker, and did not allow a banner that said, "Still, Lee Jae-myung should not be allowed," sparking controversy.
