About 72 percent of respondents in a phone survey said Democratic Party of Japan President Ichiro Ozawa should resign over a political funds scandal that has led to the indictment of his secretary, the Mainichi Shimbun newspaper said Sunday.

The support rate for Prime Minister Taro Aso's Cabinet rose 8 percentage points from the previous survey in March to 24 percent, with Aso surpassing Ozawa as more fit to be prime minister for the first time in six months, the daily reported.

According to the poll, 21 percent of the respondents said Aso was more suitable as prime minister, compared with 12 percent for Ozawa of the main opposition DPJ, although the disapproval rating for the current Cabinet remained high at 56 percent.
