Observers say its ageing support base and weakened alliance with the ruling LDP have left the faith-linked party in political limbo

The party’s stark assessment was contained in a postmortem report, formally approved on Thursday, that acknowledged the scale of the setback. At a subsequent senior party meeting, Secretary General Makoto Nishida offered his resignation, despite having only taken up the post last September.

Nishida appeared to be taking responsibility for the loss of six seats, which reduced Komeito’s presence in the 248-member chamber to 21. The party’s share of the vote also shrank by 5.37 per cent – a serious blow for a group long seen as the LDP’s reliable coalition ally.

At a press conference in Tokyo on Friday, however, party leader Tetsuo Saito announced he would not accept Nishida’s resignation, saying, “A wealth of experience and outstanding coordination skills are essential to move forward with the many issues that we face.”
