Millions of South Koreans are going to the polls to vote in a tightly contested presidential election.
Park Geun-hye of the governing Saenuri party is looking to make history as South Korea's first female president.
But she faces a tough challenge from Moon Jae-in of the Democratic United Party who has been steadily eroding her lead in the polls.
