The secretary general of the ruling Liberal Democratic Party said Sunday that Prime Minister Junichiro Koizumi is planning a Cabinet shuffle in September.

"Prime Minister Junichiro Koizumi is seriously considering whom he should appoint for the future management of national politics," Taku Yamasaki said on a Fuji Television Network program. "I don't think he has come to a conclusion yet, as the timing (of the shuffle) will be September."

Yamasaki did not deny that Koizumi might dissolve the House of Representatives and hold general elections, saying the prime minister has a propensity to do the unexpected.
