A political storm over the government's security bills intensified Wednesday as the ruling bloc restated its plan to bulldoze the bills through the Lower House as early as next week and immediately send them to the Upper House, which could enact the bills even if they get mired in deliberations.

In response, Ishin no To (Japan Innovation Party) and the Democratic Party of Japan agreed to oppose any move to table a vote soon in the lower chamber.

The alliance of Ishin and the DPJ — the two largest opposition parties — means the ruling bloc would need to force the bills through the Lower House against a barrage of criticism from most major opposition forces.
