Prime Minister Han Duck-soo, who became South Korea's acting president after Yoon Suk Yeol's impeachment, is a career technocrat whose wide-ranging experience and reputation for rationality may not be enough to stem the country's deepening political crisis.

The country’s opposition has accused acting president Han Duck-soo of obstructing justice and aiding the failed martial law bid.

SEOUL - South Korea’s opposition said on Dec 26 that it filed an impeachment motion against Acting President Han Duck-soo, after he refused to appoint Constitutional Court judges to complete the process of removing his predecessor from office.
