An opposition lawmaker was summoned Monday for questioning over allegations that he used part of his aides' salaries to create an illicit political fund, prosecutors said.

Rep. Shin Hak-yong of the main opposition New Politics Alliance for Democracy (NPAD) is accused of having deducted about 100 million won (US$93,000) from his aides' salaries between 2007 and last year.

Prosecutors believe he did this in exchange for helping them win spots on the party's proportional representation ticket.

Rep. Shin, however, denied the allegations.

"I've never withheld salaries from my aides," he told reporters as he arrived at the Seoul Central District Prosecutors' Office. "I can't imagine helping them win nominations either."

Prosecutors said the questioning will focus on what role Shin played in withholding the salaries and whether he received them for political favors.

The NPAD lawmaker is also standing trial over separate allegations of bribery. Prosecutors allege he took bribes from the head of a Seoul art school to allow it to be called a "college."

He was also indicted on charges of taking bribes from an association of private kindergartens in return for proposing a law that favors them. (Yonhap)
