Prime Minister Junichiro Koizumi said Thursday that the public corporation that will take over the state-run postal service operations in April should be headed by someone from the private sector.

The comment regarding the main pillar of his structural reform program came at a news conference held at his official residence a day after the 192-day Diet session came to a close.

Despite conditions so stringent that no private delivery firm dare enter the market, Koizumi said his administration will "step up efforts to privatize postal services through the corporation as the core of my structural reforms."
