South Korea's opposition candidate is leading in recent opinion polls with a week until the presidential election, although the gap has narrowed. Gallup Korea disclosed Tuesday that Lee Jae-myung from the main opposition Democratic Party had an approval rate of 49%,

South Korea’s presidential frontrunner Lee Jae-myung increased his lead over ruling party nominee Kim Moon-soo, according to the latest opinion poll, another sign that he is well placed to triumph in next week’s election if the conservative vote remains split.

South Korea's liberal frontrunner for president, Lee Jae-myung, was leading his main conservative rival Kim Moon-soo by more than 10 percentage points in an opinion poll issued on Tuesday, though the race has tightened a week ahead of the election.
