A motion calling for parliamentary confirmation of the new Prime Minister nominee, Moon Chang-keuk will be submitted to the National Assembly on Tuesday.
Once the request is filed, legislators have 20 days to vote on the appointment.
The ruling Saenuri Party has jumped to Moon's defense saying he needs to be given a chance to be vetted through a confirmation hearing.
Party spokesperson Park Dae-chul accused the main opposition New Politics Alliance for Democracy, or NPAD of not giving Moon a chance.
"The main opposition bloc is not even giving the nominee a chance to be questioned on stage. Not holding a confirmation hearing is anti-democratic and goes against the people's will."
The ruling party has attacked the opposition bloc, accusing it of using the controversy surrounding Moon to score political points.
However, the NPAD, which has been concentrating fire on Moon's questionable comments regarding historical issues, continues to demand his withdrawal.
"If Moon stays on it will be an insult to the people, turn Korea into a pathetic nation, cast doubt on President Park's concept of a nation and bring ridicule to the Saenuri Party."
In a lecture delivered at his church a few years ago, Moon said Japan's colonization of Korea and the division of the Korean peninsula was all part of God's will.
The National Assembly will hold a three-day interpellation session starting Wednesday signaling the start of June's extraordinary session.
