Commissioning an opinion poll on politics or any matter of public policy must be referred in advance to Chief Adviser, Politics. Consultation with the Head of Political Research is advised in most cases.
Before proposing the commissioning of an opinion poll, programme-makers should weigh up several factors, including whether it would tell us anything new, what they would do if the results contradict a preconceived "narrative", whether it is possible to track a trend, what other factors might skew the results and whether there might be any reputational damage from the BBC doing a poll on a given subject.

The BBC never commissions voting intention polls during election campaigns.
Any proposal to commission a survey on a controversial subject must be referred in advance to Chief Adviser, Politics. Its credibility will depend on having spoken to a significant and agreed proportion of the whole measurable group with an approved methodology.
When a survey has been commissioned by an outside party with an interest in the issue, the audience should be told and we should exercise real scepticism in how we treat it.
Focus Groups and Panels can provide qualitative but not, generally, quantitative data. They should not usually be treated as representative.
Any proposal to use either focus group research or a panel on party political issues must be discussed with Chief Adviser, Politics "at an early stage"- before it is commissioned.
"Straw Polls" have no statistical or numeric value. They should only be used with an explicit reference to the audience about its limitations. They should never feature in news bulletins or used to "gather serious information on party political support".
