South Korean President Park Geun-hye cannot be questioned by Tuesday as prosecutors have requested, her lawyer said, as she resists growing calls to resign over an influence scandal that has engulfed her administration.

Park is under intense pressure to step down over the crisis involving a close friend accused of meddling in state affairs, with the main opposition party seeking to put an impeachment motion up for a vote as soon as Friday.

On Monday, Park accepted the resignation of Justice Minister Kim Hyun-woong, the latest in a series of personnel reshuffles she's made amid the political scandal.
