South Korea's parliament on Friday started voting on an impeachment motion against President Park Geun-hye, who is engulfed in a corruption scandal that has fuelled calls for her to step down.

The opposition-backed motion, which requires at least 200 of the 300 members of the single-chamber assembly to impeach Park, is expected to be approved. The result of the vote is expected after about an hour.
