Her authority now transfers to the prime minister, pending a decision by the Constitutional Court on whether to ratify the decision
South Korean lawmakers on Friday voted to impeach President Park Geun-Hye, stripping away her sweeping executive powers over a corruption scandal and opening a new period of national uncertainty.
The National Assembly ballot immediately transferred Park's authority to the prime minister, pending a decision by the Constitutional Court on whether to ratify the decision and permanently remove the president from office.
A ruling could take up to six months, during which time Park will remain in the presidential Blue House -- a leader in name only. The situation leaves South Korea facing an extended stretch of political anxiety and policy paralysis at a time of slowing economic growth, rising unemployment and elevated military tensions with nuclear-armed North Korea.
Park apologises after impeachment
"I am so sorry for all South Koreans that I created this national chaos with my carelessness," Park said in a televised statement after the vote.
"But we should not let our guard down for a single minute, given the grave situation we face at home and abroad from our economy to the national defence.
In this time of uncertainty, the lives of our people should never be disregarded," she said calling on the government to unite and minimise any fallout from the resulting power vacuum.
The motion to impeach was adopted by 234 votes to 56, easily securing the required two-thirds majority in the 300-seat chamber and triggering wild celebrations among hundreds of anti-Park activists gathered outside the National Assembly.
It was a startling fall from grace for a politician who had run for the Blue House as an incorruptible candidate, declaring herself beholden to nobody and "married to the nation". After just under four years in power, she now faces the prospect of going down in history as the first democratically-elected South Korean president to be kicked out of office.
The impeachment motion had accused Park of constitutional and criminal violations ranging from a failure to protect people's lives to bribery and abuse of power. Supported by all 171 opposition and independent lawmakers, its adoption was made possible by an anti-Park faction within the president's Saenuri party.
The result means Prime Minister Hwang Kyo-Ahn, a former prosecutor who has never held elected office, suddenly finds himself in charge of Asia's fourth largest economy and supreme commander of its armed forces.
Warning on North Korea
Just minutes after the vote, Hwang urged the defence minister to tighten the national security posture. "North Korea is likely to stage some provocations to stir chaos in the South at such a grave time," Hwang was quoted as saying by a ministry spokesman.
The push for impeachment was driven by massive protests that have seen millions take to the streets of Seoul and other cities in recent weeks, demanding Park's ouster.
"This has been an honourable civil revolution in which our people defeated an incompetent leader," the president of the main opposition Democratic Party said after the vote.
The scandal that felled Park focused on her friendship with long-time confidante Choi Soon-Sil.
Choi is awaiting trial on charges of meddling in state affairs and using her Blue House connections to force dozens of conglomerates to donate around $70 million to two foundations she controlled.
In a first for a sitting South Korean president, Park has been named a "suspect" by prosecutors investigating the case. The power vacuum left by Park's ouster could be a lengthy one.
The Constitutional Court is expected to validate the impeachment, starting the clock running on a 60-day window for holding fresh presidential elections -- an event neither the ruling or opposition parties are particularly prepared for.
"This is the first step towards putting the country back on a normal track but there is a long road ahead," said Park Kie-Duck, a political science researcher at the Sejong Institute think-tank in Seoul.
High-level corruption has long been a stain on South Korea's democratic credentials and the presidential Blue House is no stranger to allegations of cronyism. Since South Korea's first free and fair election in 1987, every president has faced graft investigations after leaving office and one -- Roh Moo-Hyun -- committed suicide as a corruption probe closed in on his family.
