Yoshirō Mori
Abe is a member of the Mori Faction (formally, the Seiwa Seisaku Kenkyū-kai) of the Liberal Democratic Party. This faction is headed by former prime minister Yoshirō Mori. Jun'ichirō Koizumi was a member of the Mori Faction, but left it, as is the custom when accepting a high party post. From 1986 to 1991, Abe's father, Shintaro, headed the same faction. The Seiwa Seisaku Kenkyū-Kai has 60  members in the House of Representatives and 26 in the House of Councillors.
