The Prince of Wales will turn 73 in November, and he is both the longest-serving and oldest heir apparent in British history.
And in 2019, an actor who won plaudits for his role as Charles made a surprise claim about the future King’s relationship with the Queen.
Ahead of the release of season three of The Crown on Netflix, actor Josh O’Connor, who played Prince Charles, said: “Here is a man for in order for his life to take meaning and to take importance his mother has to die.
“That is a huge monumental philosophical thing.”
The third season of the hit Netflix show focused on events that occurred between 1964 and 1976, including Charles’ relationship with his mother as he entered adulthood, and his first encounter with Camilla Parker Bowles.
The Crown is based on historical facts, but much of the finer details are dramatised, with creator Peter Morgan confessing to taking artistic licence within Royal Family history.
It explores the notion of Prince Charles being raised knowing “he’s going to be next” and some of the friction in his relationship with Her Majesty.
Actress Olivia Colman, who made her name as Sophie in Channel 4 sitcom Peep Show, plays Queen Elizabeth II in The Crown – for which she won a Golden Globe Award.
She said: “The Queen wants to protect him but also needs him to know he’s going to be next.
“There’s some friction as well, as there would be.
“Some of his decisions are quite difficult for her and vice versa.”
Charles will only take over as King once Her Majesty chooses to abdicate, something royal insiders have previously said she will never do, or following her death.
Charles alluded to his future in the 2018 BBC documentary ‘Prince, Son & Heir – Charles at 70’.
He said: “The idea somehow that I would go on exactly the same way, if I have to succeed, is complete nonsense because the two situations are completely different.
“I think it’s vital to remember there’s only one sovereign at a time, not two, so you can’t be the same as the sovereign if you’re the Prince of Wales, the heir.”
Charles is the oldest of the Queen’s four children – with he and Anne both born many years before their younger siblings Andrew and Edward.
It is widely believed that the age difference between Charles, Andrew and Edward is one of the main reasons why they didn’t always see eye to eye.
After Elizabeth was crowned, her and husband Prince Philip’s busy diary meant Charles was left in the care of Royal Family nannies.
She explained: “He [Charles] was at Gordonstoun [School], he was miserable, he hated it.
“And there is Andrew at home being rocked by mummy and read bedtime stories and all the things that Charles probably would have wished he had been able to have if the Queen wasn’t so duty-bound right at the start of her reign.”
Meanwhile, Charles’ plans for the monarchy have been destabilised after losing “trusty lieutenant” Prince Harry, a royal expert told Express.co.uk.
His plan, according to Dr Edward Owens, was built around his family and two sons supporting him, and Harry has left a “gaping hole” at Charles’ side.
