Prime Minister Shinzo Abe is considering laying out his plan next Monday to dissolve the Lower House later in the week for a general election in October, a government source said Tuesday.

Abe is looking to hold a news conference to announce he will disband the House of Representatives on Sept. 28, when the Lower House convenes for an extraordinary session, according to the source.

In line with the schedule, official campaigning would start Oct. 10 for the election on Oct. 22, ruling Liberal Democratic Party sources said.
