Park Chan-dae, floor leader of South Korea's main opposition party, on Sunday called on acting President Han Duck-soo to promulgate special counsel bills against impeached President Yoon Suk-yeol and first lady Kim Keon-hee by Tuesday, vowing to hold him accountable if he fails to do so, Yonhap news agency reported.

Earlier this month, the National Assembly passed a special counsel bill to investigate whether President Yoon committed insurrection and other violations over his declaration of martial law.

The parliament also passed a bill mandating a special counsel probe into two key allegations involving the first lady -- her alleged involvement in a stock manipulation scheme and interference in election nominations through a power broker.
