Ban Ki Moon South Korea President

Former United Nations secretary-general Ban Ki-moon ended his attempt to seek South Korea's presidency Wednesday, dropping a lifetime of diplomacy to denounce his country's political establishment.

Ban Ki-Moon was due to arrive in South Korea on Wednesday for a six-day visit that has fuelled speculation the UN chief is lining up a tilt at the presidency of his home country.
