Yoshirō Mori
Koizumi competed for the presidency of the LDP in September 1995 and July 1998, but he gained little support losing decisively to Ryutaro Hashimoto and then Keizō Obuchi, both of whom had broader bases of support within the party. However, after Yamasaki and Kato were humiliated in a disastrous attempt to force a vote of no confidence against Prime Minister Yoshirō Mori in 2000, Koizumi became the last remaining credible member of the YKK trio, which gave him leverage over the reform-minded wing of the party.
