The main opposition Democratic Party(DP) is set to table a motion to impeach the vice chair of the state broadcasting watchdog in an apparent attempt to prevent appointment of board members at the largest shareholder of public broadcaster MBC.

DP floor spokesperson Yoon Jong-kun said on Thursday that his party is expected to adopt the motion to be reported to the plenary session later in the day as a party platform.

The motion aims to impeach Korea Communications Commission(KCC) vice chair Lee Sang-in, who is serving as the acting chair of the current two-person organization during an ongoing confirmation hearing for KCC chair nominee Lee Jin-sook.

The opposition, which is pushing to enact laws aimed at reforming governance structure of public broadcasters, is thought to be trying to prevent appointment of new board members at the Foundation for Broadcast Culture, MBC's largest shareholder.

The impeachment motion must be put to a vote between 24 and 72 hours after it is reported to the plenary.
