Former president Kim Dae-jung has been concealing the existence of an illegitimate daughter, according to an investigative programme that was to air on television last night. SBS television was showing an interview with a woman who claims to be the daughter born of an extramarital affair that Mr Kim had with a former secretary in 1970 while he was a national assemblyman. Local media reports say the woman, whose identity was to be concealed on air, claims during the interview that the former president's eldest son, Kim Hong-il, offered bribes to buy her silence. 'As a result of intensive investigations, programme producers have confirmed most of her allegations as true and uncovered evidence of living expenses given to her by Hong-il,' Yonhap news agency quoted a spokesman for SBS as saying. The illegitimate daughter is reportedly a well-educated woman in her 30s who has spent years hiding the identity of her father, according to Seoul newspapers. Her mother is said to have committed suicide after being hospitalised in June 2000. Analysts point out that this had been a particularly sensitive time for Mr Kim as he was preparing for a historic summit with North Korean leader Kim Jong-il. News of the forthcoming broadcast drew a terse reaction from the former president. 'Once we have seen the broadcast, we will issue a response,' aides for Mr Kim said. Officially, Kim Dae-jung only has two sons. The eldest, Hong-il, is the son of his first wife, while Hong-gol is his son with his current wife, Lee Hee-ho. If confirmed, the exposure of an illegitimate child will further tarnish the reputation of the former president who won the Nobel Peace Prize in 2000 for his efforts at improving tense inter-Korean relations. Since completing his presidential term in 2003, Mr Kim's' legacy has been badly tainted by revelations that his administration paid North Korea more than US$500 millions to persuade Kim Jong-il to attend the inter-Korean summit in 2000. Both his sons have also served time in prison on charges of graft stemming from Mr Kim's term in office.
