Lee Jae-myung, leader of South Korea's main opposition Democratic Party, was discharged from a hospital on Wednesday after being stabbed in the neck last week.

There were "no forces behind the attack on Lee Jae-myung," and the attacker committed the crime based on "subjective political beliefs" in order to "prevent Lee Jae-myung from becoming president," Yonhap reported, citing the police.

Lee told a televised press conference in front of the hospital in Seoul that the war-like politics of killing and eliminating opponents should be ended, expressing his hope that his incident could become an opportunity to end the politics of hatred and restore the politics of mutual respect and coexistence.

Lee was stabbed on the left side of his neck by a man in his 60s during a visit to the southeastern port city of Busan on January 2.

He was transferred by helicopter to the hospital in Seoul for surgery after receiving an emergency treatment in Busan.
