A South Korean appeals court on Friday raised the sentencing of ousted President Park Geun-hye to 25 years in prison on corruption charges, including bribery that led to her impeachment.

The Seoul High Court raised Park's sentence by one year from the lower court's ruling of the 24-year imprisonment.

Park was fined 20 billion won (18 million U.S. dollars), higher than the lower court's fine of 18 billion won (16 million U.S. dollars).

The appellate court increased the bribes Park received from Samsung Group, the country's biggest family-controlled conglomerate, in exchange for assistance to the management control transfer to Samsung Electronics Vice Chairman Lee Jae-yong from his ailing father Lee Kun-hee.
