TOKYO, March 8 (Xinhua) -- The main opposition leader Democratic Party of Japan (DPJ) president Ichiro Ozawa is under great pressure as some 57 percent of respondents in a telephone poll believed he should step down, the Mainichi Shimbun newspaper reported Sunday.
Only 33 percent of them said Ozawa's resignation is unnecessary.
According to the poll, 79 percent of the respondents also said Ozawa's explanations about the incident are unacceptable, against 12 percent who said they are acceptable.
The survey was conducted on Friday and Saturday following the arrest on Tuesday of Takanori Okubo, Ozawa's chief secretary, for allegedly taking illegal corporate donations from two political organizations related to Nishimatsu Construction Co.
It covered 1,686 households nationwide, with 1,032 people responding.
Ozawa had denied any wrongdoings and repeated that he was considering quitting ahead of an election that surveys had shown was likely to end more than half a century and almost unbroken rule of the Liberal Democratic Party.
