South Korea's main opposition vows to impeach acting president

South Korea's main opposition party leader Lee Jae-myung says his party will impeach acting president and prime minister Han Duck-soo at "the behest of the people".

Han took over as acting president from President Yoon Suk Yeol, but opposition MPs now want him removed from office too, arguing that he is refusing demands to complete Yoon's impeachment process and to bring him to justice.
