Sadakazu Tanigaki, president of the main opposition Liberal Democratic Party (LDP), on Sunday dismissed the idea of forming an alliance with the ruling Democratic Party of Japan (DPJ), Kyodo News reported. The LDP chief also called for an early general election. Separately, in an interview with public broadcaster NHK, Tanigaki said that the ongoing upper house election is a judgment for DPJ's confusion and wishful thinking as well as for a possible rebirth of the LDP. He said he will not resign as the party chief if the LDP manages to prevent the DPJ from securing the majority in the upper house.
