A key political reform committee of the Democratic Party of Japan, whose leader, Ichiro Ozawa, is mired in an illicit funds scandal, unveiled a draft report on political funds Thursday that seeks a complete ban on corporate donations.

The ban includes prohibiting companies from purchasing party tickets for politicians' fundraising activities, the DPJ said.

"It is very pleasing that the party has shown a direction" on the issue of political funds control, said Naoto Kan, the DPJ's deputy president.
