By Joyce Lee SEOUL (Reuters) -South Korea's leadership crisis will play out in the Constitutional Court, which will decide the fates of President Yoon Suk Yeol and Prime Minister Han Duck-soo, both impeached and suspended from power over a short-lived martial law.

The police are investigating whether President Yoon Suk Yeol tried to lead an insurrection when he declared martial law and plunged the country into crisis.

South Korea's opposition-controlled National Assembly voted to impeach acting President Han Duck-soo, further deepening the country's political crisis.
