South Korean lawmakers on Friday voted overwhelmingly to impeach President Park Geun-hye over an influence-peddling scandal, setting the stage for her to become the country's first elected leader to be pushed from office in disgrace.

Members of parliament voted by secret ballot with 234 in favor and 56 opposed, meaning dozens of members of Park's own conservative Saenuri Party backed the motion to remove her. At least 200 members of the 300-seat chamber needed to vote for the motion for it to pass.

Seven votes were disqualified, two members abstained and one member did not participate, the parliament speaker said.

The Constitutional Court must decide whether to uphold the motion, a process that could take up to 180 days. Park's duties were immediately assumed by Prime Minister Hwang Kyo-ahn on an interim basis.

Park, 64, is accused of colluding with a friend and a former aide, both of whom have been indicted by prosecutors, to pressure big businesses to donate to two foundations set up to back her policy initiatives.

Park, who is serving a single five-year term that was set to end in February 2018, has denied wrongdoing but apologized for carelessness in her ties with her friend, Choi Soon-sil.

Park has been under heavy pressure to quit but this week said she would await the court's ruling on the impeachment vote.
