Yuriko Koike
Koizumi remained in the Diet through the administrations of Abe and Yasuo Fukuda, but announced his retirement from politics on September 25, 2008, shortly following the election of Taro Aso as Prime Minister. He retained his Diet seat until the next general election, when his son Shinjiro was elected into the same seat representing the Kanagawa 11th district in 2009. Koizumi supported Yuriko Koike in the LDP leadership election held earlier in September 2008, but Koike placed a distant third.
