Diet heavyweight Ichiro Ozawa, leader of Seikatsu no To (People's Life Party), admitted Monday that the opposition camp failed to give voters an alternative to the ruling bloc in the Lower House election but stressed that change is still possible if they join hands.

"The public was not given alternative choices" to the Liberal Democratic Party, and the opposition forces were not fully prepared, allowing the LDP to score a landslide in Sunday's election, the leader of the minor opposition party said at a news conference in Tokyo.

"I'm sure a change of government can happen anytime once an alternative force emerges in front of the public," Ozawa said. "It's entirely dependent on whether the opposition is united enough to create" a counterbalancing force.
