Relevant Broadcasting Code clauses:
The preservation of due impartiality
(Rules 5.5 to 5.12 apply to television programme services, teletext services, national radio and national digital sound programme services.)
5.5 Due impartiality on matters of political or industrial controversy and matters relating to current public policy must be preserved on the part of any person providing a service (listed above). This may be achieved within a programme or over a series of programmes taken as a whole.
Meaning of "series of programmes taken as a whole":
This means more than one programme in the same service, editorially linked, dealing with the same or related issues within an appropriate period and aimed at a like audience. A series can include, for example, a strand, or two programmes (such as a drama and a debate about the drama) or a 'cluster' or 'season' of programmes on the same subject.
5.6 The broadcast of editorially linked programmes dealing with the same subject matter (as part of a "series" in which the broadcaster aims to achieve due impartiality) should normally be made clear to the audience on air.
5.7 Views and facts must not be misrepresented. Views must also be presented with due weight over appropriate timeframes.
5.8 Any personal interest of a reporter or presenter, which would call into question the due impartiality of the programme, must be made clear to the audience.
5.9 Presenters and reporters (with the exception of news presenters and reporters in news programmes), presenters of "personal view" or "authored" programmes or items, and chairs of discussion programmes may express their own views on matters of political or industrial controversy or matters relating to current public policy. However alternative viewpoints must be adequately represented either in the programme, or in a series of programmes taken as a whole. Additionally, presenters must not use the advantage of regular appearances to promote their views in a way that compromises the requirement for due impartiality. Presenter phone-ins must encourage and must not exclude alternative views.
5.10 A personal view or authored programme or item must be clearly signalled to the audience at the outset. This is a minimum requirement and may not be sufficient in all circumstances. (Personality phone-in hosts on radio are exempted from this provision unless their personal view status is unclear.)
Meaning of "personal view" and "authored":
"Personal view" programmes are programmes presenting a particular view or perspective. Personal view programmes can range from the outright expression of highly partial views, for example by a person who is a member of a lobby group and is campaigning on the subject, to the considered "authored" opinion of a journalist, commentator or academic, with professional expertise or a specialism in an area which enables her or him to express opinions which are not necessarily mainstream.
Matters of major political or industrial controversy and major matters relating to current public policy
5.11 In addition to the rules above, due impartiality must be preserved on matters of major political and industrial controversy and major matters relating to current public policy by the person providing a service (listed above) in each programme or in clearly linked and timely programmes.
Meaning of "matters of major political or industrial controversy and major matters relating to current public policy":
These will vary according to events but are generally matters of political or industrial controversy or matters of current public policy which are of national, and often international, importance, or are of similar significance within a smaller broadcast area.
5.12 In dealing with matters of major political and industrial controversy and major matters relating to current public policy an appropriately wide range of significant views must be included and given due weight in each programme or in clearly linked and timely programmes. Views and facts must not be misrepresented.
The prevention of undue prominence of views and opinions on matters of political or industrial controversy and matters relating to current public policy
(Rule 5.13 applies to local radio services (including community radio services), local digital sound programme services (including community digital sound programme services) and radio licensable content services.)
5.13 Broadcasters should not give undue prominence to the views and opinions of particular persons or bodies on matters of political or industrial controversy and matters relating to current public policy in all the programmes included in any service (listed above) taken as a whole.
Meaning of "undue prominence of views and opinions":
Undue prominence is a significant imbalance of views aired within coverage of matters of political or industrial controversy or matters relating to current public policy.
Meaning of "programmes included in any service�taken as a whole":
Programmes included in any service taken as a whole, means all programming on a service dealing with the same or related issues within an appropriate period.
