SEOUL - South Korean special prosecutors said they would indict Samsung's de facto chief Tuesday on bribery, embezzlement and other charges linked to a political scandal that has toppled President Park Geun-hye.
The planned indictment of Samsung Electronics vice-chairman Lee Jae-yong is a huge hit for the largest and most successful of the big businesses that dominate the South Korean economy. It also signals the still roiling state of South Korea's political and economic circles after weeks of massive demonstrations that led to Ms Park's impeachment.
The announcements of the planned indictments came after a three-month investigation by the special prosecution team, which ended Tuesday after the country's acting leader refused a request for an extension.
Prosecutors say the Samsung heir gave bribes worth $36 million to Ms Park and her confidante to help win government support for a smooth leadership transfer from Mr Lee's ailing father to Mr Lee.
Mr Lee also allegedly hid assets overseas, concealed proceeds from criminal activities and committed perjury. The 48-year-old billionaire was arrested on Feb 17. Samsung has denied wrongdoing.
Prosecutors also said they planned to indict four other Samsung executives on charges of offering bribes, embezzlement, hiding assets overseas and concealing proceeds from criminal activities.
The planned indictments mean that key figures at a powerful yet secretive Samsung office that wielded influence over dozens of Samsung affiliates face trial. Mr Lee promised in December to disband the secretive office, called the Corporate Strategy Office, which allegedly orchestrated bribery schemes centred on Choi Soon-sil, Ms Park's confidante.
Shortly after the prosecutors' announcement, Samsung announced a series of measures to improve its transparency, including disbanding the secretive office and resignations from top executives who prosecutors said they would indict. Mr Lee wasn't included in the resignations, implying he will keep his position and board membership at Samsung Electronics during court proceedings.
The office consists of close Lee's family aides who worked to help ensure the father-to-son leadership transition. Some say that the contentious merger of Samsung C&T and Cheil Industries in 2015 was also overseen by the office, not by the board of directors at the two Samsung companies. The merger, a crucial step for Mr Lee to strengthen his grip on Samsung Electronics, was a key benefit that Samsung sought from the government by offering millions of dollars to Mrs Choi's various entities, according to the prosecutors.
The merger, despite opposition from some shareholders who argued that it unfairly benefited the Lee family, was approved by shareholders thanks to the support of a state-controlled national pension fund, a key Samsung investor.
The special prosecution team said they also plan to pursue additional charges of bribery and concealing proceedings from criminal activities against Mrs Choi, who allegedly exploited her presidential ties to extort money and favours from companies and manipulate state affairs from the shadows.
The special prosecution team finished its inquiry without questioning Mrs Park, after she backed off from a Feb 9 interview. The country's acting leader, Hwang Kyo-ahn, refused to extend the investigation past Tuesday's deadline.
Mr Lee was once the face of the new Samsung, but now follows in the footsteps of his father, Samsung Electronics chairman Lee Kun-hee. The senior Lee was indicted in 2008 on charges of tax evasion and a breach of trust. He was later convicted and then pardoned by a former president.
Corruption has dogged many other business leaders in South Korea's family-controlled conglomerates, which are known as chaebol.
When the elder Lee was indicted, Samsung vowed a series of measures to improve transparency. It is expected to announce more measures following the younger Lee's indictment.
Since Mr Lee's father fell ill in May 2014, the younger Lee has stepped up his leadership role. Samsung appeared to be trying to change its top-down, hierarchical, authoritarian corporate culture under Mr Lee.
Fluent in foreign languages, educated overseas and linked to Silicon Valley luminaries, Mr Lee was seen as the new face of Samsung. Samsung promised to remove obstacles to creativity and innovation in recent years by introducing a nimble, startup-like attitude. It has increased returns to shareholders and acquired several companies outside South Korea.
