Seoul: South Korea's Acting President Han Duck-soo resigned Thursday, indicating he would run for the June 3 presidential election.

According to Qatar News Agency, Han announced his decision in an address to the nation, ending weeks of speculation over whether he would enter the election triggered by the impeachment of his former boss, former President Yoon Suk Yeol.

"Thinking of the weight of the responsibility I carry at this grave time, after thinking long and carefully about whether such a decision is in fact right and inevitable, I decided that if this is the only way, I must take it," Han said from the government complex in Seoul.

Han has been expected to announce his presidential bid Friday, as reported by Yonhap.

Meanwhile, with Han's resignation, Finance Minister and Deputy Prime Minister for Economic Affairs Choi Sang-mok will take over as the acting president.
