A South Korean court jailed Samsung Electronics Vice Chairman Jay Y. Lee for five years on Friday, convicting him of paying bribes in anticipation of favours from then president Park Geun-hye.

A Seoul Central District Court judge delivering a ruling on bribery and other charges after a six-month trial in a scandal that triggered Park’s impeachment and ouster, also found Lee guilty of hiding assets abroad and perjury.

Lee, the 49-year-old heir to one of the world’s biggest corporate empires, has been held since February on charges that he bribed Park to help secure control of a conglomerate that owns Samsung Electronics, the world’s leading smartphone and chip maker, and has interests ranging from drugs and home appliances to insurance and hotels.

Samsung Electronics did not have any immediate comment.

During the trial, Samsung acknowledged it offered to donate about 43 billion won (US$38 million) to entities backed by Park’s close friend, Choi Soon-sil, including sponsoring the equestrian career of Choi’s daughter.

In return for the contributions, prosecutors say, Samsung sought government support for a controversial 2015 merger of two of its affiliates, which helped tighten Lee’s control over the conglomerate.

Lee denied wrongdoing, and his lawyers say the 2015 merger was done on business merits.

Prosecutors had demanded a 12-year jail sentence for Lee, who also faces charges of embezzlement and perjury potentially the longest prison term given to a South Korean business leader.

Park is facing her own corruption trial, with a ruling expected later this year.

Samsung, founded in 1938 by Lee’s grandfather, is a household name in South Korea and a symbol of the country’s dramatic rise from poverty following the 1950-53 Korean War.

But over the years, it has also come to epitomize the cosy ties between politicians and powerful family-controlled business groups — or chaebols — which have been implicated in a series of corruption scandals.

South Koreans, who once applauded the chaebols for catapulting the country into a global economic power, now criticise them for holding back the economy and squeezing smaller businesses.

South Korea’s new president, Moon Jae-in, who replaced the Park after a May 9 election, has pledged to rein in the chaebols, empower minority shareholders and end the practice of pardoning corporate tycoons convicted of white-collar crime.
