Less than half of Filipinos find bribery as the most serious impeachment charge against Vice President Sara Duterte, a recent OCTA Research survey showed on Monday.

Duterte's impeachment trial in the Senate began on July 6 and is on iuts fourth week.

The survey conducted from July 4 to 11 finds 43 percent of adult Filipinos viewed bribery complaints as the most serious impeachment allegation against Duterte, well ahead of 28 percent for the misuse of confidential funds.

"Bribery remains the leading concern across virtually every major demographic category—including age, gender, residence, and socioeconomic class—indicating broad national agreement on its relative seriousness," it stated.

"While bribery dominates nationally, misuse of confidential funds remains the leading concern in several regions, illustrating meaningful geographic variation in public priorities," it added.

OCTA said the survey "findings indicate that Filipinos do not view all impeachment charges with equal weight."

The survey result also noted that complaints for unexplained wealth (10 percent) and grave threats (10 percent) are "cited by considerably smaller proportions of respondents."

Meanwhile, "eight percent say they do not know or cannot identify the most serious allegation" on the impeachment of Duterte.

The Senate, sitting as an Impeachment Court, resumed its hearing Monday regarding Article I of the case against Vice President Sara Duterte, concerning alleged misuse, questionable liquidation, and systematic misappropriation of confidential funds.

The prosecution panel presented Roderick Wamil, a state auditor of the Commission on Audit-Intelligence and Confidential Funds Office, as witness to identify and authenticate documents and prove other relevant and material matters to the impeachment of the Vice President.

Wamil audited the liquidation of confidential expenditures of the Office of the Vice President covering December 21 to 31 2022, and 1st, 2nd, and 3rd quarters of 2023, as well as the Department of Education’s confidential expenditures during the first three quarters of 2023.
