The main opposition Democratic Party of Korea (DPK) on Monday submitted a motion calling for disciplinary action against a ruling party lawmaker for accusing a DPK lawmaker of connection to North Korea following the North's recent drone infiltration.

Rep. Shin Won-sik of the PPP raised the allegations targeting Rep. Kim Byung-joo of the DPK, questioning how the DPK learned before the military that one of the five North Korean drones penetrated the no-fly zone around the presidential office in Seoul on Dec. 26.

Kim, a former Army general, said he found out about the penetration by checking Google Maps, and any Seoul citizen can do that.

"Rep. Shin damaged the reputation of not only Rep. Kim but of the DPK," DPK spokesperson Lee Soo-jin told reporters after submitting the motion to the National Assembly.

The DPK floor leader said the party will also consider taking legal measures against Shin, saying he is committing slander by implying that the DPK is "a puppet of North Korea." (Yonhap)
