Prince Philip: PM will not attend the duke's funeral, No 10 says
Only 30 people - expected to be the duke's children, grandchildren and other close family - can attend the funeral at St George's Chapel, Windsor.
The public has been asked to stay away.
The Prince of Wales paid tribute to his "dear papa" on Saturday, saying he will be missed "enormously".
Speaking from his Highgrove home in Gloucestershire, Prince Charles said his late father was a "very special person who... above all else would have been amazed by the reaction and the touching things that have been said about him".
The prince said he and his family were "deeply grateful" for this, adding: "It will sustain us in this particular loss and at this particularly sad time."
