The royals refuse to give interviews
Why don't members of the royal family ever give press conferences or appear on news programmes? Why is it always press officers - rather than the Windsors themselves – that respond to negative royal stories?
It's because there is a longstanding convention that royals only ever give very carefully managed interviews, whose questions have been agreed in advance. The Queen doesn't give interviews at all.
The royals are public servants, just like MPs or civil servants, and should be held to account by the media.
