South Korea's opposition-controlled Parliament introduced an impeachment motion today against President Park Geun-hye, setting up a likely vote tomorrow on whether to suspend her powers over a political scandal. A parliamentary official said, the motion to a plenary session, which means an impeachment vote, must take place between 24 and 72 hours. Tomorrow is the final day of the current parliamentary regular session.<br/><br/>Political observers said, the motion needs two-thirds approval in the 300-seat single-chamber parliament to pass. The opposition and anti-Park independents have 172 seats and they appear to have secured enough support from ruling party dissenters to pass an impeachment.<br/>If the vote passes, the country's Constitutional Court will have up to 180 days to determine whether to formally end Park's presidency.
