turns out that candidate Park Ji-won, the chief of the National Intelligence Service, borrowed 50 million won from a sponsor and did not pay it back for the past five years. In response, candidate Park Ji-won said that he has reported to the National Assembly every year as a debt, and that the United Nations party has room for illegal political funds.

is the document of the borrower submitted to the National Assembly by candidate Park Ji-won.

Candidate Park borrowed 50 million won from Mr. A on August 28, 2015.

The annual interest was 5.56%, which was due to be paid back by August 27, 2016, a year later.

However, candidate Park has been found not to have paid the principal until now, almost four years after he decided to pay the money back.

The United Party says it is an unreasonable transaction that has not paid the principal and interest for the fifth year.

A member of the UNDP insisted, "I have the potential to see it as an illegal political fund," and Joo-Ho Joo, a spokesman for the ruling party, announced a thorough verification that "we will focus on the 50 million won debt problem."

In response, candidate Park refuted the allegations, saying, "We have reported to the National Assembly every year because of normal inter-individual bonds and debts."

He added, "We have extended the date to pay back by the 27th of next month," and added, "The related content has already been registered in the Ethics System of the Office of Personnel Innovation in 2017."

Mr. A, the representative of the telecommunications equipment company that lent money to candidate Park, has given political support to the candidate for 5 million won each year from 2008 to 2018, and the company is suspected of having grown rapidly during the Kim Dae-jung administration.

In a phone call with SBS, Mr. A said, "What is the problem with lending money to a 55-year-old friend?"
