South Korean democratic politician. A member
of the National Assembly from 1954 and
president of the New Democratic Party (NDP)
from 1974, he lost his seat and was later
placed under house arrest because of his
opposition to President Park Chung Hee. In
1983 he led a pro-democracy hunger strike but
in 1987 failed to defeat Roh Tae-Woo in the
presidential election. In 1990 he merged the
NDP with the ruling party to form the new
Democratic Liberal Party (DLP).
