Prime Minister Shinzo Abe said Monday the heavily criticized Political Funds Control Law needs no further revision and again voiced support for his new farm minister, Norihiko Akagi, who like his predecessor is under fire over reported expenditure claims.

The opposition camp is linking Akagi with the same kind of accounting discrepancies that plagued Toshikatsu Matsuoka, who hanged himself in May.

According to political sources, an Akagi support group lists its headquarters as the house of his parents in Ibaraki Prefecture. The group has reported enormous office expenses — 123 million yen between 1990 and 2005.
