The motion to impeach President Yoon Suk Yeol will be put to the vote at around 7 p.m. on Saturday, the main opposition Democratic Party of Korea said Thursday.

According to the party, the bill for launching an independent counsel investigation into first lady Kim Keon Hee will be voted on at the same time.

The Democratic Party and five other minor opposition parties tabled the motion to impeach the president at the National Assembly plenary session that kicked off around 12:50 a.m. Thursday.

The move came after the opposition jointly submitted the motion, following the National Assembly's decision around 1 a.m. Wednesday to pass a motion nullifying Yoon's declaration of emergency martial law through a unanimous vote by 190 members of the 300-member Assembly who were present at the site.

The impeachment motion was signed by 191 opposition lawmakers with no lawmakers from the ruling People Power Party participating. The ruling party also boycotted Thursday's plenary meeting.
