A plenary vote on a pair of contested prosecution reform bills is set to take place later Wednesday afternoon after floor leaders of rival political parties failed to find common ground in a last-minute meeting.

Coming out of the meeting with the Democratic Party(DP) floor leader Park Hong-keun and National Assembly Speaker Park Byeong-seug, People Power Party(PPP) floor leader Kweon Seong-dong said neither party changed their stances.

The ruling party has vowed to pass the two bills meant to strip away the prosecution's investigative powers before the end of Moon Jae-in government's term despite strong objection from the main opposition.

With that, Speaker Park has scheduled a parliamentary plenary session to vote on the bills at 5 p.m. on Wednesday, where the PPP have pledged to fight the move with a filibuster.
