Following the impeachment of President Yoon Suk-yeol in April, after his unconstitutional declaration of martial law, the election has become a referendum on the future of South Korea’s democracy

After months of political turmoil, South Koreans will head to the polls Tuesday to elect a president to succeed disgraced former leader Yoon Suk Yeol, who was ousted from office over his ill-fated decision to impose martial law in December.

Thousands of supporters of South Korea's two leading presidential candidates rallied on Saturday in Seoul, days before a vote triggered by the ex-leader's disastrous declaration of martial law.
