The ruling Liberal Democratic Party's new leader Fumio Kishida, who is expected to be appointed prime minister on Monday, plans to dissolve the Lower House on Oct. 14 and a general election is likely to be held Nov. 7, government and ruling party sources said Saturday.

With the plan, campaigning for the general election is expected to start Oct. 26 with voting and ballot counting on Nov. 7, the sources said.

However, campaigning could alternatively start Nov. 2 with voting on Nov. 14 because Kishida intends to attend the Oct. 30-31 summit of the Group of 20 major economies in Rome, according to the sources.
