Separately, prosecutors asked a court to hand down a 25-year prison term to Choi, who was at the center of the massive corruption scandal that led to impeachment and arrest of Park.

The Seoul Central District Court will hand down its judgment on Shin on Jan. 26.

The court is also set to issue a separate sentence on Shin on Dec. 22 on charges of embezzlement and breach of trust.

Prosecutors suspect that Shin paid 50 billion won in wages to people who never worked for its affiliates and inflicted 130 billion won in losses on the business group's subsidiaries by forcing them to cover the losses of other units. Prosecutors have demanded a 10-year jail term for the business tycoon.

Industry watchers say a guilty verdict, if issued, could deal a heavy blow to the country's fifth-largest conglomerate, which has been moving to settle a holding firm system.

In October, Lotte established the holding company Lotte Corp. in a bid to solidify Shin's leadership and boost the group's managerial transparency.

The legal battle is the latest headache to hit the retail giant.

Lotte Group is said to have incurred about 2 trillion won ($1.78 billion) in damages in recent months amid a Seoul-Beijing diplomatic spat over Seoul's deployment of a US missile defense system.

Lotte became a key target of Beijing's ire when it provided its golf course in March as the host site of the Terminal High Altitude Area Defense, seen as a security threat by China.

Beijing took punitive action against the conglomerate's business in China. Eighty-seven of its 112 Lotte Mart discount stores suspended operations, and sales at the handful of stores that managed to stay open dipped more than 80 percent. The conglomerate decided in September to give up and announced it would sell off its local chain.

Founded in Japan in 1967, Lotte grew into one of South Korea's major chaebol, driven by its success in the retail, food and amusement businesses. The group's business includes chemicals, duty-free, finance and construction, and it has a global workforce of 125,000. (Yonhap)
