A presidential election was held in the Liberal Democratic Party of Japan on 20 September 2006 after the incumbent party leader and Prime Minister Junichiro Koizumi announced his intention to resign, a year after he led the party to victory in a snap election. Shinzō Abe won the election,[1] (only to resign a year later triggering another leadership election). His chief competitors for the position were Sadakazu Tanigaki and Taro Aso. Yasuo Fukuda was a leading early contender, but ultimately chose not to run. Former Prime Minister Yoshirō Mori, to whose faction both Abe and Fukuda belonged, stated that the faction strongly leant toward Abe.[2] Abe was subsequently elected Prime Minister with 339 of 475 votes in the Diet's lower house and a majority in the upper house.[3]
