Ahead of their resignation date, the Duke and Duchess of Sussex recently confirmed that they will no longer use 'Sussex Royal' as part of their branding.
The couple released a divisive statement on their website announcing the news.
"While there is not any jurisdiction by The Monarchy or Cabinet Office over the use of the word 'Royal' overseas, The Duke and Duchess of Sussex do not intend to use 'Sussex Royal' or any iteration of the word 'Royal' in any territory (either within the UK or otherwise) when the transition occurs spring 2020," the statement reads.
"While there is precedent for other titled members of the royal family to seek employment outside of the institution, for the Duke and Duchess of Sussex, a 12-month review period has been put in place."
The couple will official step down on March 31 with their revamped website and social media channels set to launch shortly.
