For international nurses day earlier in the week, Her Majesty the Queen, Charles, Camilla, William, Kate, Anne and Sophie made calls to thank nurses across the world.
For the Queen, this was a great milestone.
In 1940, she gave her first public broadcast on the wireless, speaking to the children of the Commonwealth in a landmark address captured by a solemn black and white photograph.
Eight decades on and the Queen has broken new ground once again at the age of 94, permitting the first broadcast of audio from an all-family video call to thank nurses for their “very important” work.
"This is rather an important day,” said the Queen. “They [nurses] have obviously had a very important part to play recently."
It is understood to be the first time that the Queen has given permission for direct audio from one of her one-on-one conversations to be aired.
