Seoul: The National Assembly on Tuesday passed a ruling Democratic Party-led bill extending the mandate of a comprehensive special counsel investigation into unresolved allegations involving former President Yoon Suk Yeol and his wife.

According to Yonhap News Agency, the bill was approved unanimously in a 173-0 vote during a plenary session shortly after a 24-hour filibuster by the main opposition People Power Party (PPP) ended. Lawmakers of the PPP and the minor Reform Party boycotted the vote.

Under the provisions of the bill, the investigation period will be extended by 30 days from the current deadline of July 24 to August 23. Additionally, the number of public officials dispatched to the special counsel team will increase from 130 to 150, and the scope of the probe will be expanded to include obstruction of audits by public officials.

The comprehensive special counsel investigation consolidates three separate special counsel probes into Yoon's imposition of martial law in December 2024, allegations involving former first lady Kim Keon Hee, and the death of a young Marine. It was initiated in February to address key allegations that were not fully covered by the previous probes.
