Meghan Markle and Prince Harry will no longer use their "Sussex Royal" branding, a spokeswoman for the couple has said.
The Duke and Duchess of Sussex reportedly spent a fortune trademarking the Sussex Royal brand after dramatically quitting their roles as senior royals last month.
The couple had hoped to continue using the name for their charitable brand and trademarked dozens of items from literature to t-shirts and bandannas under the Sussex Royal banner.
But it appears they have reluctantly accepted the Queen's demands to drop all official Royal Family branding in the future.
The spokeswoman said: "While The Duke and Duchess are focused on plans to establish a new non-profit organisation, given the specific UK Government rules surrounding use of the word Royal, it has been therefore agreed that their non-profit organisation, when it is announced this Spring, will not be named Sussex Royal Foundation.
"The Duke and Duchess of Sussex do not intend to use 'Sussex Royal' in any territory post Spring 2020."
The couple said on Wednesday that their lives as working royals will end on March 31 when they stop representing the Queen and become financially independent.
Harry and Meghan will embark on a new chapter in North America, but sources have stressed they "will be in the United Kingdom regularly" .
They will retain the same charitable goals supporting causes from the Commonwealth to mental health.
According to reports, Meghan had told pals that using the word royal "shouldn't even be an issue in the first place and it's not like they want to be in the business of selling T-shirts and pencils".
A source told the Daily Mail: "Meghan said she's done with the drama and has no room in her life for naysayers, and the same goes for Harry."
She reportedly claimed the couple picked the name Sussex Royal to "protect the royal name, not profit off it".
Friends also claim she said their "success is inevitable" regardless of whether they can use the name or not.
