Prime Minister Yoshiro Mori will meet the No. 2 man of the Liberal Democratic Party on Wednesday to decide the timing and formula of the party's presidential election.

The presidential election will decide Mori's successor as party president and, by extension, prime minister.

At a regular gathering of LDP executives Monday, Mori set up the meeting with LDP Secretary General Makoto Koga to take place after the government unveils an emergency package of economic measures.
