MANILA - (UPDATE) The net trust rating of Vice President Leni Robredo hiked to "very good" in the last quarter of 2017, a survey by the Social Weather Stations released Tuesday showed.

The survey, conducted from December 8 to 16, 2017, found 66 percent of adult Filipinos with much trust, 20 percent undecided, and 14 percent with little trust in Robredo.

This gives her a net trust rating of +52.

Robredo's net trust rating saw a 16-point increase from the +36 she received in September. The rise also put her a grade higher from her earlier "good" mark.

The vice-president's net trust ratings improved to very good in Mindanao, Visayas and Balance Luzon, while stayed moderate in Metro Manila, the survey said.

SWS also noted that public satisfaction with the performance of Robredo as vice president was higher among those with much trust in her.

In an SWS survey released late last month, Robredo saw a steady "good" net satisfaction rating of +42, a point higher than her +41 in September.

"It was a very good +69 (78% satisfied, 9% dissatisfied) among those with much trust in her, compared to the moderate +19 (44% satisfied, 25% dissatisfied) among those who were undecided, and the very bad -53 (19% satisfied, 72% dissatisfied) among those with little trust in her," the pollster said.

Conducted from December 8 to 16, 2017 using face-to-face interviews of 1,200 adults nationwide, the survey had sampling error margins of ±3% for national percentages, and ±6% each for Metro Manila, Balance Luzon, Visayas, and Mindanao.
