Closing the official 12-day campaign period, political party leaders on Saturday made their final appeals before today's general election for the Lower House.

While the ruling coalition leaders stressed unity and achievements by their tripartite bloc in their speeches, opposition parties called for a change in power.

"Changing of alliances among political parties would adversely affect the general public. Parties must form a coalition based on mutual trust. The opposition force should also present a possible framework of alliance," Prime Minister Yoshiro Mori said in a speech delivered jointly with the other two coalition leaders in Yokohama.
