SEOUL: President Park Geun-hye's job approval rating dropped to an all-time low this week, a new poll said on Friday, a development underscoring challenges faced by the female leader. The survey on 1,009 adults found only 29 percent of those polled approved of the way Park has been handling her job, down 1 percentage point from a previous week, according to Gallup Korea. It marked the first time that Park's approval rating has tumbled to levels below 30 percent.YONHAP NEWS
