Prime Minister Han Duck-soo, who was impeached on Friday as South Korea's acting president, is a career technocrat whose wide-ranging experience and reputation for rationality failed to shield him from growing political turmoil.

Han Duck-soo, who is the Prime Minister of South Korea, took over the president’s powers after Yoon Suk Yeol was impeached nearly two weeks ago. But why does the opposition Democratic Party want to impeach Han?

A day after Han Duck-soo vowed not to appoint three judges for the Constitutional Court, the main opposition party impeached the acting president.
