Foreign Minister Makiko Tanaka is planning a major reshuffle of senior ministry personnel — including the ministry's top bureaucrat — after the July 20-22 Group of Eight summit in Genoa, Italy, ministry sources said.

Tanaka's plan stems from her dissatisfaction over disciplinary actions imposed on ministry officials in the wake of the recent scandal involving a logistics chief charged with swindling huge sums in discretionary government funds.

The radical shuffle could widen the rift between Tanaka and senior ministry officials that emerged soon after the outspoken minister assumed the post in late April.
