Risa Niigaki
As of June 1, 2007, Miki Fujimoto resigned from Morning Musume, due to the tabloid magazine "Friday" running an article depicting Fujimoto and comedian Tomoharu Shoji in a relationship. Ai Takahashi replaced Fujimoto as leader (a position the latter occupied for the briefest period in the group's history—26 days), and Risa Niigaki became subleader.
