The Charity Commission is to probe a complaint made about transfers of funds between the Sussexes’ and Cambridges’ charitable foundations.
Harry and Meghan received an “unrestricted grant” of £145,000 from William’s Royal Foundation to start up Sussex Royal, with a further £151,856 for their sustainable travel initiative Travalyst.
The latter is now a private limited company.
Graham Smith, from anti-monarchy group Republic, wrote in a letter to the Charity Commission: “These two charities appear to be in breach of guidelines.”
The Duke of Sussex’s legal team said: “Both The Charity Commission’s own statement today, as well as that of The Royal Foundation, state there is no determination of wrongdoing here.
“All of the duke’s charitable activities are fully transparent as well as compliant with Charity Commission guidelines.”
They were fully in line with governance requirements and were reported transparently.”
The Duke and Duchess of Sussex did not respond to requests for comment.
The Charity Commission tonight confirmed it would examine the claims.
A spokeswoman for the commission said: “We have received a complaint on this issue.
“As with all concerns raised with us we will assess the information provided to determine whether or not there is a role for the Commission.
“We have not made any determination of wrongdoing.”
Harry and Meghan, who now live in Los Angeles, are in the process of setting up their new charity Archewell.
The name is derived from the Greek word arche, meaning “sources of action”, and the inspiration for the name of their son, Archie Mountbatten-Windsor.
