South Korea's opposition Democratic Party on Monday urged the country's Constitutional Court to swiftly rule on President Yoon Suk Yeol's impeachment, saying keeping the country waiting is "irresponsible" and deepening social division.

South Korean President Yoon Suk Yeol, who lawmakers voted to impeach and was indicted on criminal charges for declaring martial law last December, was cleared to be released from detention on Friday.

The Constitutional Court of Korea, which has been deliberating the impeachment case against President Yoon Suk Yeol for more than 15 days, is likely to set a record as Korea's lengthiest presidential impeachment case.
