Changwon: A self-proclaimed power broker at the center of a growing political scandal will appear before prosecutors Friday for questioning over allegations that he fabricated the results of public opinion polls in favor of then-presidential candidate Yoon Suk Yeol in exchange for the nomination of a candidate in the 2022 parliamentary by-elections.According to Yonhap News Agency, Myung Tae-kyun, who runs a public polling agency, will appear for questioning at the Changwon District Prosecutors Office in the city about 300 kilometers southeast of Seoul at 10 a.m. Friday, his lawyer Kim So-yeon said.Myung is suspected of receiving approximately 90 million won (US$65,200) from Kim Young-sun, a former lawmaker of the ruling People Power Party (PPP), on several occasions between August 2022 and December last year in exchange for his help in getting her nominated on the PPP ticket ahead of the 2022 by-elections.Myung allegedly won the nomination for Kim in exchange for conducting customized polls in favor of then PPP presidential candidate Yoon for free. First lady Kim Keon Hee has also been suspected of involvement in the nomination process."Myung has all the evidence he needs to be able to defend himself," his attorney said. "We plan to sort out the facts and respond faithfully to the prosecution's questioning."Kim, the former lawmaker, appeared twice before prosecutors this week as a suspect in the case. She has denied the allegations against her.
