This ends AFP's Live Report on the South Korean presidential election with exit polls showing only the slimmest of margins between the two candidates in a potentially historic poll for the country..
South Koreans vote in the presidential election at a polling station in Nonsan, 150kms south of Seoul, on December 19, 2012. South Koreans went to the polls to choose a new president in a close and potentially historic election that could result in Asia's fourth-largest economy getting its first female leader.
As polling booths closed at 6:00 pm (0900 GMT), a joint exit poll by three TV stations gave Park 50.1 percent of the vote, with 48.9 percent for Moon. The closeness of the figures now means that no clear result is likely to emerge until around midnight local time (15:00GMT) according to South Korea's main television channel KBS.
