South Korean President Park Geun-hye has replaced her prime minister and two other top officials in a bid to restore public confidence amid a political scandal that has sunk her approval ratings to an all-top low.

The scandal involves Park’s friendship with Choi Soon-sil, the daughter of a cult leader in South Korea. Park admitted last week that she had given drafts of her speeches to Choi to edit. The news media also speculates that Choi, who holds no government title, has meddled in government affairs for personal gain.

Choi has been placed under detention. Park issued an apology last week, but pressure continues to mount for her to resign.
