The daughter of a former military ruler won South Korea’s presidential election on Wednesday and will become the country’s first female leader, saying she would work to heal a divided society.The 60-year old conservative, Park Geun-hye, will return to the presidential palace in Seoul where she served as her father’s first lady in the 1970s, after her mother was assassinated by a North Korean-backed gunman.With more than 88 percent of the votes counted, Park led with 51.6 percent to 48 percent for her left-wing challenger, human rights lawyer Moon Jae-in, giving her an unassailable lead that forced Moon to concede.Her raucous, jubilant supporters braved sub-zero temperatures to chant her name and wave South Korean flags outside her house. When she reached her party headquarters, Park was greeted with shouts of "president”.An elated Park reached into the crowd to grasp hands of supporters wearing red scarves, her party’s color. "This is a victory brought by the people’s hope for overcoming crisis and for economic recovery,” she told supporters at a rally in central Seoul.Park will take office for a mandatory single, five-year term in February and will face an immediate challenge from a hostile North Korea and have to deal with an economy in which annual growth rates have fallen to about 2 percent from an average of 5.5 percent in its decades of hyper-charged growth.She is unmarried and has no children, saying that her life will be devoted to her country.The legacy of her father, Park Chung-hee, who ruled for 18 years and transformed the country from the ruins of the 1950-53 Korean War into an industrial power-house, still divides Koreans.For many conservatives, he is South Korea’s greatest president and the election of his daughter would vindicate his rule. His opponents dub him a "dictator” who trampled on human rights and stifled dissent."I trust her. She will save our country,” said Park Hye-sook, 67, who voted in an affluent Seoul district, earlier in the day. "Her father ... rescued the country,” said the housewife and grandmother, who is no relation to the candidate.For younger people, the main concern is the economy and the creation of well-paid jobs in a country where income inequalities have grown in recent years.
