Opposition parties on Wednesday asked that a review be held at a parliamentary political ethics panel for 44 lawmakers involved in a political funds scandal that has rocked the ruling Liberal Democratic Party.

The main opposition Constitutional Democratic Party of Japan, Nippon Ishin no Kai and the Japanese Communist Party made the request to the LDP's Kazunori Tanaka, who heads the Deliberative Council on Political Ethics of the House of Representatives.

The LDP told the CDP at a meeting of their parliamentary affairs leaders earlier in the day that it would support such a request.
