Eighty-four percent of Koreans in their 20s and 30s believe no political party speaks for them, according to a recent poll.

The survey was conducted in June and July among 1,202 people between 20 and 39 by Prof. Yun Won-cheol of Hanyang University's College of Economics and Finance for the Office of the Minister for Special Affairs. It was submitted to Democratic Party lawmaker Chun Hye-sook on Tuesday.

Some 38.5 percent said they like none of the existing political parties because they doubt the effectiveness of the party system itself. Some 29.1 percent said they dislike political parties because they only incite strife, and 27.7 percent said because what they do has nothing to do with the interests of voters.

Asked if they considered voting a duty, 43.6 percent of respondents in their 20s and 41.4 percent of those in their 30s said yes.

Some 17.1 percent each said they will not vote because they are disappointed with politics and because they doubt voting makes any difference.
