EDITING PRESIDENT'S SPEECHES

Ms Choi Soon Sil had a say in some of President Park Geun Hye's speeches. She told Segye Ilbo newspaper last week she was able to help Ms Park "find the right words to express herself" as she "knows what is in her mind and heart".

REVIEWING PRESIDENTIAL OFFICE REPORTS

Ms Choi allegedly reviewed reports from the Blue House that were up to 30cm thick almost every day. She used them in meetings with her own advisers to discuss policy issues and draft plans that went back to the Blue House.

SHAPING NORTH KOREA POLICY

Ms Choi allegedly predicted North Korea would collapse in two years, and Ms Park is rumoured to have implemented foreign policies based on this. A 2014 speech which set her vision for reunification was found in a discarded laptop belonging to Ms Choi.

MASTERMINDING CULTURAL PROJECTS

Ms Choi was accused of being the mastermind behind many key projects by the Ministry of Culture, Sports and Tourism, mostly led by her film director friend Cha Eun Taek. Vice-Culture Minister Kim Chong, appointed in 2014, was also accused of collaborating with Ms Choi.

ABUSING PRESIDENTIAL LINK TO RAISE FUNDS

Ms Choi was accused of abusing her friendship with the President to press conglomerates to donate to two non-profit groups she founded. The funds are suspected to have been diverted to finance her lifestyle and other schemes.
