Main opposition Democratic Party (DP) leader Lee Jae-myung’s acquittal this week on election law charges strengthens his presidential ambitions amid President Yoon Suk-yeol’s ongoing impeachment trial, while also casting a spotlight on his remaining criminal cases that may shape South Korea’s political future.

If Yoon is removed from office and an early election is called, Lee’s legal troubles could collide with the political calendar, raising questions over his viability and eligibility as a candidate.
