South Korea's President Yoon faces impeachment motion

Impeaching him would require support from 200 of the National Assembly's 300 members

- 

South Korea's opposition parties Wednesday submitted a motion to impeach President Yoon Suk Yeol over the shocking and short-lived martial law that drew heavily armed troops to encircle parliament before lawmakers climbed walls to reenter the building and unanimously voted to lift his order.

Impeaching Yoon would require the support of two-thirds of parliament, and at least six justices of the nine-member Constitutional Court would have to endorse it to remove him from office. The motion, submitted jointly by the main liberal opposition Democratic Party and five smaller opposition parties, could be put to a vote as early as Friday.

Yoon's senior policy advisers and Defense Minister Kim Yong Hyun offered to resign as the nation struggles to make sense of what appeared to be a poorly-thought-out stunt. The Democratic Party on Wednesday submitted a separate motion to impeach Kim, who it alleged recommended the martial law declaration to Yoon.
