열린우리당
As a result of the controversy concerning the capital, and public dissatisfaction of economic development, Uri party lost much of its popularity. When the Uri party was defeated in by-elections held on 30 April 2005, losing every one of the 23 electoral districts, Uri Party lost its majority in the National Assembly. Facing the outcome of his unpopularity, Roh took a rather strange measure to manage the government when he proposed a grand coalition with the opposition Grand National Party. Roh's rationale was that since it was impossible to continue his presidency with an approval rate of around 20 percent, a grand coalition comprising the Uri party and the Grand National Party was desirable, and that the difference between both parties in terms of political agendas was actually minute. Roh promised he would yield much of his power and might even resign from office if a grand coalition was successfully launched.
