quit easily," said Kazuhiro Harada, a DPJ Lower House lawmaker. "I promised the public that we would make (Ozawa) prime minister."

One DPJ Lower House lawmaker who asked to remain anonymous, however, expressed dissatisfaction.

"I'm going to follow the decision (of the party executives), but I still want an explanation of how we can go into the next election under a leader who said we were still not capable of coming to power," he said.

During the news conference Sunday at which Ozawa suddenly expressed his intention to resign, he criticized the DPJ for still lacking strength and said it would be difficult to win the next Lower House election on its own.
