The United Kingdom is amongst one of the many countries that do not overtly ban advertising that is likely to cause offense to certain religious groups. Extreme cases would not be authorised for broadcast or print and could well be subject to criminal proceedings. Instead, the United Kingdom’s Advertising Standards Authority, a non-governmental organisation, provides advice and guidance for advertisers. In an increasingly diverse and complex United Kingdom, advertisers can inadvertently make mistakes. The ASA advises avoiding anything linked to a central tenet or sacred symbol, texts or spiritual figures. It also makes the point that as Christianity is the predominant faith, that the public are more accommodating providing advertising is not disrespectful. Is it necessary to legislate to protect religious beliefs?
