SEOUL -- Kweon Seong-dong, the floor leader of the South Korean ruling party, said on Sunday that his party has rejected a proposal by the country's main opposition party to set up a consultative body to stabilize the operation of state affairs.

The People Power Party is still the ruling party and an acting president has already been appointed according to the Constitution, Kweon said at the National Assembly on Sunday.

Earlier in the day, Lee Jae-myung, leader of the main opposition Democratic Party, said in a press conference that it is imperative for the country to realize a speedy normalization as the national defense and security posture have been undermined by the "insurrection" incident, referring to the botched emergency martial law imposition earlier this month by the now-impeached President Yoon Suk-yeol.

Lee called on the country's parliament and government to set up a consultative body to stabilize the operation of state affairs in the spirit of multi-party cooperation in governance.
