Lawmakers in Korea's National Assembly have agreed to hold a full and thorough investigation into last month's Sewol-ho ferry disaster.
The 90-day probe will begin on Monday.
A plenary session of the National Assembly passed the proposal by an overwhelming majority of 224 out of 226 participating lawmakers, with 2 abstentions.
The agreement comes after days of wrangling between rival parties over whether to include specific names of witnesses in the joint proposal.
The main opposition New Politics Alliance for Democracy had been demanding the inclusion of presidential chief of staff Kim Ki-choon.
The ruling Saenuri Party insisted on leaving the selection of witnesses to a special parliamentary committee.
As a compromise, the two sides agreed to subject presidential office officials to the probe, with the head, Kim Ki-choon, being required to report to hearings.
