The Jakarta Globe quotes the head of the Indonesian Public Opinion Survey Association, Andrinof Chaniago, saying that the organisation would introduce a code of conduct and audit those members “that have used faulty methodology or those that have created public unrest”.

Meanwhile, the Indonesian Public Research Association’s secretary general Umar Bakri said his organisation had already issued several warnings to members over questionable techniques.

Bakri, who also chairs the country’s National Survey Council, said: “That is the importance of the association, to keep the pollsters on the right track.”
