South Korean lawmakers on Friday impeached President Park Geun-hye, a stunning and swift fall for the country's first female leader amid protests that drew millions into the streets in united fury.

After the vote, parliamentary officials hand-delivered formal documents to the presidential Blue House that stripped Park of her power and allowed the country's No. 2 official, Prime Minister Hwang Kyo-ahn, to assume leadership until the Constitutional Court rules on whether Park must permanently step down. The court has up to six months to decide.

"I'd like to say that I'm deeply sorry to the people because the nation has to experience this turmoil because of my negligence and lack of virtue at a time when our security and economy both face difficulties," Park said after the vote, before a closed-door meeting with her Cabinet where she and other aides reportedly broke down in tears.

Hwang separately said that he wanted "the ruling and opposition political parties and the parliament to gather strength and wisdom so that we can return stability to the country and people as soon as possible."

Once called the "Queen of Elections" for her ability to pull off wins for her party, Park has been surrounded in the Blue House in recent weeks by millions of South Koreans who have taken to the streets in protest. They are furious over what prosecutors say was collusion by Park with a longtime friend to extort money from companies and to give that confidante extraordinary sway over government decisions.

Organizers said about 10,000 people gathered in front of the National Assembly to demand that lawmakers pass the impeachment motion. Some had spent the night on the streets after traveling from other cities. Scuffles broke out between angry anti-Park farmers, some of whom had driven tractors to the assembly from their farms, and police. When impeachment happened, many of those gathered raised their hands in the air and leapt about, cheering and laughing.

"Can you hear the roar of the people in front of the National Assembly?" Kim Kwan-young, an opposition lawmaker said ahead of the vote, referring to South Korea's formal name. "Our great people have already opened the way. Let's make it so we can stand honorably in front of history and our descendants."

The handover of power prompted the prime minister to order South Korea's defense minister to put the military on a state of heightened readiness to brace for any potential provocation by North Korea. No suspicious movements by the North were reported, however.

Park will be formally removed from office if at least six of the Constitutional Court's nine justices support her impeachment, and the country would then hold a presidential election within 60 days.

National Assembly speaker Chung Sye-kyun said the bill on Park's impeachment was passed by a vote of 234 for and 56 opposed, with seven invalid votes and two abstentions. That well surpassed the necessary two-thirds vote needed in the 300-seat assembly, with the opposition getting strong support from members of Park's party.

Relatives of the victims from a 2014 ferry disaster that killed more than 300 and was blamed in part on government incompetence and corruption, who were in the parliament observing the vote, cheered and clapped after the outcome was announced. Most lawmakers left the hall quietly, though some could be seen taking selfies as they waited to vote.

Once called the "Queen of Elections" for her ability to pull off wins for her party, Park has been surrounded in the presidential Blue House in recent weeks by millions of South Koreans who have taken to the streets in protest. They are furious over what prosecutors say was collusion by Park with a longtime friend to extort money from companies and to give that confidante extraordinary sway over government decisions.

Her approval ratings had plunged to 4 percent, the lowest among South Korean leaders since democracy came in the late 1980s, and even elderly conservatives who once made up her political base have distanced themselves from her. An opinion survey released Thursday showed about 78 percent of respondents supported Park's impeachment.

South Korean lawmakers last voted to impeach a president in 2004, when they accused late liberal President Roh Moo-hyun of minor election law violations and incompetence. The court restored Roh's powers about two months later, ruling that his wrongdoings weren't serious enough to justify his unseating.
