OSAKA -- Vote-rigging charges surrounding the election of Liberal Democratic Party lawmaker Kenji Koso, a former senior official of the posts ministry, continued to widen Thursday with the arrest of a former head of the general affairs bureau of the Kinki Postal Administration Office.
Isao Fujinaga, 60, a resident of Ibaraki, Osaka Prefecture, currently heads the secretariat of a body of postmasters in charge of privately run post offices in the Kinki region.
He is suspected of using his position to solicit votes for Koso, who was elected in the July 29 House of Councilors election from the LDP's proportional representation list.
