South Korean President says she’ll resign if parliament finds a plan for safe transfer of power

South Korean President Park Geun-hye said on Tuesday that she will resign her office once parliament develops a plan for a safe transfer of power, amid prosecution claims that she colluded with a friend who wielded government power from the shadows.

Ms. Park would be the first South Korean leader to resign since the country’s first president, Syngman Rhee, quit and then fled to Hawaii amid a popular uprising in 1960. The succeeding government was overthrown by a coup by Ms. Park’s late father, the military dictator Park Chung—hee, whose rule also abruptly ended after he was assassinated by his spy chief in 1979.

“I will leave the matters about my fate, including the shortening of my presidential term, to be decided by the National Assembly,” Ms. Park said on Tuesday in a live address to the nation, referring to parliament. “If the ruling and opposition parties discuss and come up with a plan to reduce the confusion in state affairs and ensure a safe transfer of governments, I will resign from the presidential position under that schedule and by processes stated in law.”

Opposition parties had been closing in on an impeachment motion against Ms. Park, and even her allies in the conservative ruling party have called for her to “honorably” step down rather than face impeachment.

An impeachment motion vote had been planned for Friday. The country’s two largest opposition parties were also planning on Tuesday to nominate a special prosecutor to independently investigate the scandal.

At the heart of the scandal is Choi Soon-sil, Ms. Park’s longtime friend and the daughter of a late cult leader who allegedly meddled in state affairs and pressured companies to donate millions of dollars to foundations controlled by her at the request of Ms. Park.

Prosecutors have so far indicted Ms. Choi, two ex-presidential officials and a music video director known as a Ms. Choi associate for extortion, leakage of confidential documents and other charges.

Ms. Park, who has immunity from prosecution while in office, has refused to meet with prosecutors. Her lawyer, Yoo Yeong-ha, has described prosecutors’ accusations against Ms. Park as groundless.
