SEOUL -- Lee Jae-myung, presidential candidate of South Korea's majority liberal Democratic Party, led a poll for the June 3 presidential election, Flower Research survey showed Monday.

Lee came out on top with a support rate of 52.1 percent, taking a big lead over Kim Moon-soo, the second-biggest conservative People Power Party's presidential candidate who garnered 29.5 percent of support.

The human rights lawyer-turned-politician maintained his position as a presidential frontrunner in the June 3 election, triggered by the removal of former President Yoon Suk-yeol from office over his botched martial law imposition last December.

Lee lost the 2022 presidential election to Yoon by the country's narrowest margin of 0.73 percentage points.

The Democratic Party won an approval score of 50.3 percent, while 32.0 percent supported the People Power Party, the survey showed.

The result was based on a poll of 2,007 voters conducted between Friday and Saturday. It had plus and minus 2.2 percentage points in margin of error with a 95-percent confidence level.
