HRH, an abbreviation of His/Her Royal Highness, is used as part of the title of some members of the Royal Family. The new arrangements, which will begin in the spring, mean the couple Harry and Meghan will no longer use their HRH titles and will not formally represent the Queen.
The duke and duchess will receive no public funds for royal duties and intend to repay £2.4m of taxpayer money used for the refurbishment of Frogmore Cottage.
It came as the Queen went to church near Sandringham in her first public appearance since it was announced the couple were giving up their HRH titles.
In her statement yesterday she wished them “a happy and peaceful new life”.
But Thomas Markle, Meghan’s father, accused them of “cheapening” the Royal Family.
Speaking at a summit in Berlin, Mr Johnson said he had been confident the Royal Family would find a way forward for Prince Harry and Meghan, adding: “I think the whole country will want to join in wishing them the very best for the future.”
The Queen was met by about 100 well-wishers outside St Mary the Virgin Church in Hillington, Norfolk, where she arrived with the Duke of York.
Announcing the decision over the duke and duchess in a statement on Saturday, she said she was “particularly proud” of how quickly Meghan became one of the family and said she, Harry and Archie would always be “much loved”.
