South Korea’s government was paralyzed Monday, mired in a new constitutional crisis after President Yoon Suk Yeol of South Korea clung to his office, but his own party’s leader suggested that he had been ousted from power.

Yoon has barely been seen in public since his ill-fated decision last week to declare martial law. Meanwhile, Han Dong-hoon, chair of Yoon’s People Power Party (PPP), has presented himself as the government’s decision maker and said the president is no longer running the country.

The trouble is that South Korea’s constitution doesn’t allow for anyone to replace the president unless he resigns or is impeached.
