Seoul, Dec 12 (IANS): Han Dong-hoon, the chief of South Korea's ruling People Power Party (PPP) on Thursday expressed support for impeaching President Yoon Suk Yeol over his declaration of martial law last week, calling on his party's lawmakers to vote based on their own "conviction."

Han Dong-hoon made the remarks as the opposition Democratic Party (DP) is set to file a new motion to impeach Yoon after a parliamentary impeachment vote failed Saturday as the majority of PPP lawmakers boycotted it, Yonhap news agency reported.

"We must stop further confusion. There is only one effective method now," Han said in a press conference. "In the next (impeachment motion) vote, our party's lawmakers should enter the assembly hall and take part in the vote based on their own conviction and conscience."

When asked whether he supported Yoon's impeachment, Han affirmed, "Yes," adding that there is no other way.

Han said Yoon has no intention of stepping down from office early, effectively breaking his promise to leave all decisions, including his term, to the PPP during his address last Saturday.
