Overhaul of system to include consumption tax increase, PM says

Prime Minister Naoto Kan's ruling coalition lost its upper house majority in a weekend election, putting his policies to deal with debt and generate growth at risk and prompting warnings by credit rating agencies S&P and Fitch on Japan's sovereign ratings.
