Liberal Democratic Party President Sadakazu Tanigaki pledged Sunday at his party's annual convention to lead the fight to corner the ruling Democratic Party of Japan into dissolving the Lower House for a snap election.

"This year's goal is to drive the DPJ into a Lower House snap election and re-establish an LDP-led government," Tanigaki told his colleagues at the Grand Prince Hotel Akasaka in Chiyoda Ward, Tokyo. "The DPJ's campaign platform is just lip service," he said.

Participants also vowed to stand united so the LDP will prevail in April's municipal elections.
