South Korea ? Embattled Samsung Group Chairman Lee Kun-hee said today he would step down from his post at the top of South Korea’s biggest conglomerate following his indictment on tax evasion charges.

“I have decided to resign from the post of chairman,” Lee told a news conference less than one week after he was indicted following a special independent counsel investigation into the conglomerate’s operations.

“We, including myself, have caused troubles to the nation with the special probe,” Lee said. “I deeply apologize for that, and I’ll take full responsibility for everything, both legally and morally.”

Special prosecutors last week indicted Lee on charges of evading $113 million in taxes, ending a three-month probe in the family-run conglomerate prompted by allegations of wrongdoing by a former Samsung lawyer.
