The Liberal Democratic Party is planning to hold its triennial presidential election on Sept. 20, with Prime Minister Shinzo Abe expected to secure re-election without opposition, a senior LDP official said Tuesday.

The Sept. 20 election may be officially promulgated on Sept. 8 before Abe's LDP presidential term expires at the end of September.

Following the LDP race, Abe is considering reshuffling party executives and his Cabinet in October, senior LDP lawmakers said.
