Former British Prime Minister David Cameron told Norah O'Donnell of "CBS Evening News" that the role of the monarch in the United Kingdom is mostly ceremonial.
After his mother, Queen Elizabeth II, passes away on September 19, King Charles III of the United Kingdom ascends to the throne and gives this interview.
In her seven decades in power, she appointed fifteen different prime ministers, including Cameron.
Cameron informed O'Donnell that between 2010 and 2016, while he was prime minister, he held practise audiences with Charles to prepare him for when he took the throne.
After all, his mother "couldn't live forever," as Cameron put it.
I think he knew one day he would take on the job.
"Although for those of us, you know, born since 1952, we've always had the queen. And it feels like a rock of our lives has disappeared."
