SEOUL, South Korea — South Korea’s National Assembly voted Friday on a motion to impeach President Park Geun-hye, whose government has been consumed by a corruption scandal. The motion accuses her of “extensive and serious violations of the Constitution and the law.” Prosecutors have also accused her of crimes in connection with the scandal, though as president she cannot be indicted.

Here are the accusations against Ms. Park, which she has dismissed, through her spokesman and her lawyer, as a “house of cards”:

Extortion and abuse of power

In their indictment of Ms. Park’s longtime friend Choi Soon-sil, which named Ms. Park as an accomplice, prosecutors made the following accusations:

• In 2014, Ms. Park told an aide, Ahn Chong-bum, to help a company run by one of Ms. Choi’s associates secure a contract with Hyundai Motor. Mr. Ahn relayed the request to Hyundai, and the company won an $860,000 contract. Ms. Choi received kickbacks worth $44,000, including a Chanel handbag, from her associate.

• In a series of meetings in July 2015, Ms. Park asked the chairmen of eight large companies to contribute to two new foundations, meant to promote South Korean culture and sports. Ms. Park asked Ms. Choi to build and run them. With the help of presidential aides, Ms. Choi pressured the companies into donating the equivalent of $69 million to the foundations.

• In January of this year, Ms. Choi started a sports management company called the Blue K. With the backing of Ms. Park and Mr. Ahn, she coerced the conglomerate Lotte into donating $6 million for a sports complex that the company hoped to build and manage. In February, Ms. Park asked the steel maker Posco to help Ms. Choi’s company; under pressure from Mr. Ahn, Posco agreed to create a fencing team so that the Blue K could manage it.
