The Duke and Duchess of Cambridge have officially renamed their charity - formalising their split from Meghan Markle and Prince Harry .
Kate and William have legally changed the name of the organisation to the Royal Foundation of the Duke and Duchess of Cambridge, according to documents published by Companies House today.
It is the final step in Harry and Meghan's split from the former joint charity, after they broke away to set up their own Sussex Royal foundation.
The move followed reports of a rift, first between Kate and Meghan, then between William and his younger brother Harry.
Sources at the time denied there was a feud, saying it was "largely about preparing both couples for their future roles, which are obviously on divergent tracks".
The charity split was first reported last year but it was officially announced earlier this year.
The statement says both couples are "incredibly proud of what they have achieved together" but claims the new structure will "best support Their Royal Highnesses with future charitable activity".
The brothers set up the Royal Foundation in 2009 and Kate joined two years later after marrying William , and she has been a key part of its work since.
Meghan joined the trio on stage for the first time in the lead up to her wedding for what was due to be an annual meeting - earning them the nickname the Fab Four.
A fee of £10 was paid to Companies House by William and Kate's charity to file the "Notice of change of name by resolution", just 14 months after they amended the name to include Meghan when she married into the royal family.
The Royal Foundation has yet to update the title on its website, which still also features images of the Sussexes.
Meghan and Harry officially registered their own charity - the Sussex Royal Foundation - in July.
However according to a royal source people have been mocking their chosen name , saying it sounds like a potato.
They told the Sun : "The new name is all about Harry and Meghan building their brand and doing it their way.
"But the name is a little surprising as we were expecting something a bit more traditional."
William, Kate, Harry and Meghan's joint venture was intended to harness the star power of the four high-profile royals.
They were dubbed the Fab Four after taking to the stage together at the first - and so far only - Royal Foundation forum in London in February 2018.
At the time, Harry said "working as family does have its challenges", but insisted "we're stuck together for the rest of our lives".
The Sussexes' plan for their own separate charity was unveiled in June this year, and last week they appointed influential media executive Karen Blackett, chairwoman of MediaCom UK, as their first trustee.
