Given the announcement of a royal engagement, the Clearance team at Radiocentre is expecting lots of queries about mentioning the Royal Family in radio ads.
Usually, references to or portrayals of members of the Royal Family in ads are likely to only be acceptable with prior permission.
Having said that, references to the Royal Family in the context of advertisements for books, newspaper articles, films, events and so forth are likely to be acceptable without prior permission, as long as these references are not offensive, defamatory or derogatory.
It is unlikely that an ad using the national anthem will be cleared as this may cause offence to some listeners.
So it’s a royal minefield, but Clearance is well placed to answer the anticipated flurry of questions relating to this romance.
