Prime Minister Yoshiro Mori will make a comment in the near future about the ruling Liberal Democratic Party's presidential race, which will choose his successor, LDP Secretary General Makoto Koga said Sunday.

In a speech in Akita, Koga said, "We cannot allow a continuation of instability in politics and the administration."

Mori has agreed to move up the LDP presidential race from September to as early as April, paving the way for his resignation as the nation's prime minister and head of the LDP. But when and how to hold the election has yet to be decided.

In a separate appearance in the town of Iitagawa in Akita Prefecture, Koga said he still hopes to see his former one-time faction boss Koichi Kato become prime minister.
