The rebellion against Naoto Kan is far from over and a few more lawmakers are likely to get on the bandwagon, a Democratic Party of Japan source said Friday, fueling speculation the uprising within the party could force the prime minister to step down.

In a move highlighting the administration's shaky foundation, a DPJ executive reportedly has asked a senior member of New Komeito to support bills needed to implement the fiscal 2011 budget in exchange for Kan's resignation.

Chief Cabinet Secretary Yukio Edano did not deny the report, saying only that party leaders are united in addressing a host of pressing issues.
