Meghan Markle news: The Sussex royals stood down from the Royal Family earlier this year
Harry and Meghan permanently stepped back from royal duties in 2021.
A statement from Buckingham Palace said at the time: “Following conversations with The Duke, The Queen has written confirming that in stepping away from the work of The Royal Family it is not possible to continue with the responsibilities and duties that come with a life of public service.
“The honorary military appointments and Royal patronages held by The Duke and Duchess will therefore be returned to Her Majesty, before being redistributed among working members of The Royal Family.
“While all are saddened by their decision, The Duke and Duchess remain much loved members of the family.”
In response, the Sussexes said they “remain committed to their duty and service to the UK and around the world, and have offered their continued support to the organisations they have represented regardless of official role.”

“They need the time, space and the trust.”
