日本新党
In October 1991, Prime Minister Kaifu Toshiki failed to attain passage of a political reform bill and was rejected by the LDP, despite his popularity with the electorate. He was replaced as prime minister by Miyazawa Kiichi, a long-time LDP stalwart. Defections from the LDP began in the spring of 1992, when Hosokawa Morihiro left the LDP to form the Japan New Party. Later, in the summer of 1993, when the Miyazawa government also failed to pass political reform legislation, thirty-nine LDP members joined the opposition in a no-confidence vote. In the ensuing lower house election, more than fifty LDP members formed the Shinseitō and the Sakigake parties, denying the LDP the majority needed to form a government.
