South Korea's ruling Democratic Party on Wednesday elected Moon Hee-sang, a six-term lawmaker, as its candidate for parliamentary speaker.

Moon beat out rival Park Byeong-seug, a five-term lawmaker, by 67 to 47 in a vote cast by party lawmakers.

In his victory speech, Moon Hee-sang said that as partners of the National Assembly, ruling and opposition lawmakers should both cooperate and keep each other in check.

He also expressed hope to make parliament an organization that can be trusted and win the people's respect.

The National Assembly will hold a plenary session on May 24th to put the confirmation to a vote.
