Liberal Democratic Party rebels who voted against the government's postal privatization bills in the House of Representatives are still considering forming a new party ahead of the Sept. 11 election, a key dissenter said Friday.

"You will face various limits in campaigns if you run in an election as an independent," LDP heavyweight Shizuka Kamei said in Tokyo. "I am having serious discussions with my partisans on whether it would be better to form a new party to gain voter understanding."

The rebels are also deliberating whether voters will accept the new party if it is being formed only because they can't run on the LDP ticket, he said.
