This is stated in a statement by British Queen Elizabeth II, published by Buckingham Palace.
“The Duke and Duchess of Sussex will no longer use the titles of Their Highnesses, and will no longer be considered acting members of the royal family,” the statement said.
Also, Prince Harry and Megan will no longer be able to represent the queen at official events.
Changes in the official status of the prince and his wife will take effect this spring.
Earlier it was reported that the British Queen Elizabeth II supported the decision of Prince Harry and his wife Meghan Markle to abandon royal privileges.
