TOKYO (Reuters) – A fledgling party led by popular Tokyo governor Yuriko Koike gained momentum on Thursday ahead of an Oct. 22 election as the biggest opposition Democratic Party said it would step aside to let its candidates run under her conservative, reformist banner.

An Asahi newspaper poll showed 13 percent planned to vote for her party, versus 32 percent for the LDP.
Both surveys asked voters their preference for proportional representation districts where ballots are cast for parties, rather than …
