The leader of the ruling People Power Party (PPP) plans to hold a press conference on Monday, officials said Sunday, amid growing calls for his resignation after President Yoon Suk Yeol was impeached.

Earlier in the day, PPP leader Han Dong-hoon abruptly cancelled a press conference where he had been expected to announce his resignation.

Han will instead hold the presser at 10:30 a.m. Monday, according to PPP officials.

Han had earlier vowed to continue his duties in response to calls for his resignation after the National Assembly voted to impeach Yoon on Saturday.

He has since faced growing pressure to step down after all five elected members of the PPP's Supreme Council expressed their intent to resign.

Han expressed support for Yoon's impeachment on Thursday despite his earlier calls for Yoon's "orderly" resignation.

Should Han step down, floor leader Kweon Seong-dong will become the acting head of the ruling party. (Yonhap)
