Prince Charles and Camilla, Duchess of Cornwall, Prince William and Kate, Duchess of Cambridge, and Sophie, Countess of Wessex, are expected to join the monarch in her speech which is designed to show the family united.
Queen Elizabeth and senior members of the royal family will appear on TV to address the nation on 7 March, just hours ahead of Oprah Winfrey’s interview with Harry and Meghan on CBS.
The traditional Commonwealth Service at Westminster Abbey on 8 March won’t be held this year because of the coronavirus crisis, so the monarch will deliver her speech a day earlier.
The change in the schedule may have important consequences as the forthcoming interview which the Sussexes gave to Oprah has already stirred much controversy on both sides of the Atlantic. The Mirror reported that the interview might have to be re-edited or even partially re-shot because of the rift it has caused with the Queen and Prince William, and because of the hospitalisation of 99-year-old Prince Philip.
