SEOUL, Jan 21 - A South Korean court on Wednesday sentenced former Prime Minister Han Duck-soo to 23 years in jail for charges including engaging in a key action of insurrection concerning ex-President Yoon Suk Yeol's declaration of martial law in December 2024.

The Seoul Central District Court found Han guilty because he was considered instrumental in setting up the outward appearance of a cabinet meeting that facilitated the martial law declaration, a judge said, calling it a "top-down insurrection".
