The prosecutors' recommendation ends a four-monthlong trial into allegations against Samsung's 49-year-old vice chairman, Lee Jae-yong. Lee was arrested earlier this year as the corruption scandal prompted months of massive public protests that culminated in the ouster of president Park Geun-hye.

In his closing remarks, special prosecutor Park Youngsoo said Samsung's alleged bribing of the president was typical of the corrupt and cozy ties between the government and big businesses.

Such dealings once helped fuel the country's rapid industrialization but now increasingly are being scrutinized as illegal and unfair. Park accused Samsung officials of lying in their testimonies to protect Lee.

Lee was indicted in February on charges that included offering $38 million in bribes to four entities controlled by a friend of then-president Park. Prosecutors believed that the bribery was offered in exchange for government help with a merger that strengthened Lee's control over Samsung at a crucial time for organizing a smooth leadership transition after his father fell ill. Prosecutors allege the money was paid to a company in Germany to bankroll equestrian training for the daughter of a friend of Park.

Park was removed from office in March and is being tried separately. Her friend Choi Soon-sil also is on trial. Lee has denied all charges. He has said he did not know of Choi or her daughter before the scandal grabbed national headlines and said the succession situation at Samsung was not discussed during three meetings he held with the former president.

Samsung's lawyers do not contest having donated a large sum of money to entities controlled by Choi. They disagreed with the prosecutors regarding the nature of the fund and insisted that at the time the donations were made Samsung was unaware that Choi controlled them.

Prosecutors also are seeking heavy penalties for four other former Samsung executives who had belonged to a once-powerful corporate strategy office that handled such activities.

Prosecutors asked the court to imprison Lee's mentor Choi Gee-sung, a former vice-chairman at Samsung Electronics, for 10 years. They are seeking seven to 10 year prison terms for three other former Samsung executives.
