The National Assembly has passed a revised bill proposed by the main opposition Democratic Party of Korea (DPK) on launching a special counsel investigation into impeached President Yoon Suk Yeol over his failed martial law bid.

The revised bill was approved in a 188-86 vote during an Assembly plenary session Friday, with ruling People Power Party (PPP) lawmakers voting against it . The opposition bloc currently dominates the 300-member parliament with 192 seats.

The opposition-proposed bill excludes allegations that Yoon committed "treason" by attempting to deliberately provoke war with North Korea from the original proposed by the DPK and five other parties.

The PPP has argued that the scope of the bill is excessive and decided to introduce its own bill that excludes such allegations.

The move came after DPK floor leader Park Chan-dae and his PPP counterpart, Kweon Seong-dong, failed to reach a compromise in talks presided over by National Assembly Speaker Woo Won-shik.

Park said the DPK has decided to unilaterally table the revised bill, stressing the party has made "major compromises" on the scope of the special counsel probe bill.

After the bill's passage, PPP floor leader Kweon called on acting President Choi Sang-mok to immediately demand the Assembly reconsider it. (Yonhap)
