Ok, you've gone a bit giddy and you've posted and tweeted about the big engagement news. All well and good. We all wish the happy couple well.
But now you're looking for creative ways to capitalise on the latest royal announcement. Before you do so in a commercial context, you will need to pause and consider the rules for a moment, or it might be off with your head!
Strictly speaking, as a brand/advertiser, the UK advertising codes say that unless you have permission, you may only feature members of the Royal Family in pretty limited circumstances, whether in TV advertising (which is covered by the BCAP Code) or adverting and marketing in any other media (which will usually be covered by the CAP Code).
However, when there's a royal event or occasion such as a royal engagement (congrats to HRH Prince Harry and Meghan), birthday or anniversary (congrats to HM The Queen and HRH Prince Philip), or a new baby on the scene (not long to go now...), in practice there can be a bit more scope to do so, provided you don't go too far and don't create the impression of patronage or endorsement by the Royal Family.
However, there are a few pitfalls to avoid. In particular you must remember not to feature the Royal Arms or emblems in advertising/marketing materials, or the Lord Chamberlain will do the modern equivalent of sending you to the tower.
No doubt CAP/ASA will be dusting off their guidance shortly for this latest royal engagement.
Prince Harry is to marry his American actress girlfriend Meghan Markle. The prince, fifth in line to the throne, will marry Ms Markle in spring 2018... The couple, who have been dating since the summer of 2016, secretly got engaged earlier this month. They posed for photographs outside Kensington Palace, with Prince Harry saying he was "thrilled" and it had been a romantic proposal.
