Japan's LDP set for big win in Sunday election: polls TOKYO (Reuters) - Japan's conservative Liberal Democratic Party (LDP) is on track for a stunning victory in Sunday's election, returning to power with hawkish former Prime Minister Shinzo Abe at the helm, and possibly ending Japan's political gridlock. Opinion polls by the Asahi, Yomiuri and Nikkei newspapers on Friday forecast that the LDP was headed for a hefty majority in the 480-seat powerful lower house of parliament. The LDP and its smaller ally, the New Komeito party, could gain the two-thirds needed to break through a policy deadlock that has plagued the world's third biggest economy since 2007. However, between 30 percent and nearly 50 percent of voters were undecided with just days to go, said the surveys, and turnout was likely fall below the 69.28 percent seen in the last lower house poll in 2009. An LDP win on Sunday would usher in a government committed to a tough stance in a territorial row with China, a pro-nuclear power energy policy despite last year's Fukushima disaster and a radical recipe of hyper-easy monetary policy and big fiscal spending to end persist ant deflation and tame a strong yen. The surveys also showed that Prime Minister Yoshihiko Noda's Democratic Party of Japan (DPJ), which surged to power three years ago promising to pay more heed to consumers than corporations and break bureaucrats' stranglehold on policymaking, could win fewer than 70 seats. That would be its worst showing since its founding in 1998, Nikkei said. A new right-leaning party created by popular Osaka Mayor Toru Hashimoto and now led by outspoken nationalist Shintaro Ishihara was struggling and might win fewer than 50 seats, the Asahi newspaper showed. If the LDP and the New Komeito party control a two-thirds majority in the lower house it would make it easier for the new government to pass policies. The new government would have the power to over-ride the upper house, which can block legislation and where no party has a majority. Reporting by Linda Sieg; Editing by Michael Perry
