The wife of South Korea's ousted former president has been sentenced to 20 months in jail for accepting bribes from the controversial Unification Church.

However, the court cleared 52-year-old Kim Keon Hee on charges of stock price manipulation and receiving free opinion polls from a political broker before the 2022 presidential election, which was won by her husband Yoon Suk Yeol.

Yoon has already been sentenced to five years' in jail for abusing power and obstructing justice in relation to his failed martial law bid in 2024.

This marks the first time in South Korea's history that a former presidential couple are convicted at the same time.

On Wednesday, a judge at the Seoul Central District Court ruled that Kim had "misused her position as a means of pursuing personal gain".
