Prime Minister Han Duck-soo, who became South Korea's acting president after Saturday's impeachment of Yoon Suk Yeol, is a career technocrat whose wide-ranging experience and reputation for rationality could serve him well in his latest role.

South Korea's parliament has impeached President Yoon Suk Yeol over his martial law decree, ending days of political paralysis.

South Korean President Yoon Suk Yeol vowed to “never give up” after lawmakers voted to impeach him Saturday, leaving him on the verge of being ousted after he shocked the nation by briefly imposing martial law.
