Tokyo Gov. Yuriko Koike's new political party is leading the race for the Tokyo Metropolitan Assembly election, followed closely by the ruling Liberal Democratic Party, a poll showed Sunday.

The gap is close enough that the forces backing the governor might win a majority in the 127-seat assembly because Koike's Tomin First no Kai (Tokyoites First) and Komeito have forged an alliance, according to the weekend telephone survey conducted in the capital by Kyodo News.

The election will be held on July 2.
