Japan’s ruling party will likely debate the fate of beleaguered Prime Minister Shigeru Ishiba at a gathering in the next few days amid rising calls for a leadership change.

Hiroshi Moriyama, the Secretary General of the Liberal Democratic Party, said Tuesday that a plenary meeting will be held in the near future, while he said it remains to be decided what exactly might be discussed at the meeting.

The fate of Ishiba will likely be on the agenda after some LDP lawmakers on Monday stepped up their calls for Ishiba to resign to take responsibility for the party’s election setback on July 20. What’s decided at the coming meeting will have weight because it’s a venue where the party can formally decide on a range of key matters.
