The Queen is to make a Commonwealth TV address after her annual service was cancelled due to coronavirus.
The annual Commonwealth Day service due to take place on Monday, Mar 8, attended by the Queen and members of the royal family, will not go ahead due to the pandemic, Westminster Abbey has said.
To mark Commonwealth Day, the Queen will instead share her annual message in A Celebration For Commonwealth Day, which will be broadcast on Sunday, Mar 7 on BBC One.
The Prince of Wales, the Duchess of Cornwall, the Duke and Duchess of Cambridge and the Countess of Wessex will also take part in the programme, the Abbey said.
Those not taking part will be the Duke and Duchess of Sussex after their confirmation last week they will not be returning as working members of the royal family.
Harry and Meghan quit as senior working royals in March 2020 to earn their own money in the US, where they have signed deals with Spotify and Netflix estimated to be worth more than £100 million.
Stepping down as working royals also means the couple will be stripped of their military, Commonwealth and some other patronages.
In a timetable coincidence, they will be appearing on screens across the world for their exclusive interview with US chat show host Oprah Winfrey.
The intimate conversation - Oprah With Meghan And Harry: A CBS Primetime Special - will be aired on Mar 7 in the US, while British broadcasters scramble for the TV rights.
