Voting begins in election to replace ousted South Korean president Park
South Koreans have begun voting in the election to replace ousted president Park Geun-hye.
Early voters can cast ballots on Thursday and Friday at about 3,510 polling stations across the country before the election next Tuesday, the National Election Commission said in a statement.
It is South Korea's first presidential election with early voting after introducing it for parliamentary and mayoral elections in recent years, the statement said.
Pre-election surveys show liberal candidate Moon Jae-in comfortably leading his two main rivals - a centrist and a conservative.
The winner will be sworn in as the new president immediately, forgoing the usual two-month transition. Ms Park's impeachment and removal from office changed South Korea's election schedule, so the new president will serve one full five-year term.
Ms Park is currently being held in a detention centre near Seoul awaiting trial on allegations that she extorted money from businesses, took kickbacks from some of those companies and committed other wrongdoing, all in collaboration with a longtime confidante. The trial is to formally start later this month.
A commission-run website showed about 4 million people had voted by mid-afternoon. South Korea has 42,479,710 eligible voters, according to the election commission.
