TOKYO (AFP) - Japan's centre-left prime minister, struggling with the quake, tsunami and nuclear disaster recovery and a flagging economy, had a no-confidence motion tabled against him by his opponents Wednesday. Three junior ministers and two parliamentary secretaries from Naoto Kan's Democratic Party of Japan (DPJ) resigned late Wednesday, a sign that they would vote for the motion in the Diet legislature on Thursday, local media said. Kan's key rival inside the DPJ, scandal-tainted veteran Ichiro Ozawa, said he would support the move against the prime minister, as did members of his faction and former premier Yukio Hatoyama, Kyodo news reported.
