South Korean President Roh Moo-hyun has instructed prosecutors to consider reopening a probe into a financial scam allegedly involving the front-running presidential candidate.
In a statement released Sunday, Mr. Roh said a videotape had surfaced in which frontrunner Lee Myung-bak admitted having founded the company at the center of the 2001 scandal.
Lee, a former Hyundai executive and Seoul mayor running as the Grand National Party's candidate, has been heavily favored to win Wednesday's election.
Lee was suspected of involvement in a scam in which his ex-partner, Kim Gyeong-jun, allegedly manipulated the price of stocks in a company he owned.
South Korean prosecutors announced earlier this month that they had found no evidence that the conservative politician was involved in stock market manipulation.
