South Korea's prime minister has offered to resign amid a bribery scandal about two months after he took up the country's No. 2 post.

Lee Wan Koo has been at the center of a corruption scandal that flared after a businessman killed himself earlier this month with a memo listing the names of high-profile figures he claimed to have bribed.

Businessman Sung Wan-jong told a local daily before his death he gave 30 million won ($27,390) to Lee in 2013. Lee has denied this.

Lee's office said Tuesday he conveyed his resignation offer Monday to President Park Geun-hye.

It wasn't known if Park would accept Lee's resignation offer.

South Korea's executive power is concentrated in the president but the prime minister leads the country if the president becomes incapacitated.
