Election campaigning kicks off in South Korea

The candidates vying to lead South Korea kicked off their official campaigns Monday ahead of a snap presidential election to replace the country's impeached ex-leader, removed over a thwarted martial law bid. On June 3, South Korean voters will pick a new president. 

For 22 days from Monday, the six officially registered presidential candidates will campaign across the country. The frontrunner by a large margin, polls show, is main opposition Democratic Party candidate Lee Jae-myung, with 43 percent support. The country's conservative People Power Party said Sunday that former labour minister Kim Moon-soo would be their official candidate.
