President Yoon Suk Yeol called opposition leader Lee Jae-myung on Wednesday to wish him good health before Lee goes on a weeklong vacation for hospital treatment later this week, Lee's main opposition Democratic Party of Korea (DPK) said.

Yoon made the call at around 2:40 p.m. and expressed concern for his health, while Lee expressed his gratitude, the DPK said.

Lee will take a weeklong leave from Thursday to next Wednesday to get treatment, which he had postponed due to the recent general elections. His office earlier refused to disclose details about his illness or health condition.

A DPK official said Yoon made the phone call after hearing via media reports that Lee will be hospitalized. (Yonhap)
