Since being invested as Prince of Wales by his mother, the Queen, in July 1969, he has worked to support her and forge his own path within the Royal Family as heir to the throne.
With the support of his wife Camilla, Charles has taken on more responsibility at The Firm as the Queen begins to slow down, after turning 95 last month.
He has also taken the helm of several family affairs and helped the Queen decide on the logistics of Meghan Markle and Prince Harry who stepped down from their management positions last year.
Charles’ plans for a lean monarchy when he takes the throne are well known, and he is reportedly looking to have a team of seven royals – not counting Prince Harry, Meghan Markle or Prince Andrew.
Royal author Angela Levin told talkRADIO: “Prince Charles has long wanted to downsize the monarchy to cut costs and make people worth the money they got from the taxpayer.
“I imagine that could be the time when Harry and Meghan will be abandoned by the royal family.
“I think the outer edge, which the Queen wanted to keep together for a very long time for sentimental reasons, which at her age she didn’t particularly particularly want a change which I think is understandable.
“But he wants to change and I think he will. “

The first steps for a small senior royals are already in place and the Queen revealed her new squad of eight royals over Christmas last year.
Her ‘new venture’, featuring The Queen, Charles, Camilla, Princess Anne, The Duke and Duchess of Cambridge, Prince Edward and Sophie Wessex, came together for a reunion photo at Windsor Castle after the Covid lockdown.
The arrangement fits Prince Charles’ long-term vision for a lean monarchy as well as the Queen’s mantra of ‘you have to see to be believed’.
Courtiers have been asked to plan events for the eight senior members, unofficially dubbed the “new business.”
A royal source said: “The family is united to explore the possibilities of working together to highlight the causes close to their hearts, help each other and help the country at the same time.
“The Queen has often said that they ‘have to be seen to be believed’ – this comes from the top. “
Charles has already stepped in to control the spending of Princesses Beatrice and Eugenie, which is said to have sparked a huge row with Prince Andrew.
A report released after Eugenie’s sabbatical found she spent more than £ 100,000 of taxpayer dollars to blast India, America, Thailand and South Africa.
She paid for the hotels and travel herself, but the massive security bill, including overtime, was funded by the taxpayer.
Speaking on the Channel 5 documentary Beatrice and Eugenie: Pampered Princesses ?, Royal expert Richard Kay said: “She was sort of moving from country to country, as most young people do. the middle class who take years off.
“But, of course, she was accompanied by bodyguards from the police.
“This meant that we, the taxpayers, were paying the police to accompany him to the beasts of the world.”
Charles reportedly stepped in to control spending, with author Angela Levin telling the program that he suggested Eugenie and Beatrice did not need expensive security as they are unlikely to ever become members of the Royal family.
Ms Levin added: ‘Prince Charles decided that since they were probably not very elderly royals it was too expensive for the public to pay so he stopped that. Prince Andrew was so angry that he wrote a note to the Queen. He said he wanted them to be seen as real members of the royal family. He didn’t want the protection officers to leave them. ”
When Charles takes the throne, many members of the royal family will be given different titles to reflect their new roles.
At the moment he is the Prince of Wales but this title is not his alone and is the official title of the Heir to the Throne. He is the 21st man to have it.
Diana became the Princess of Wales after marrying Charles in 1981.
Technically, Camilla should now have the title but she turned it down out of respect for Diana given the complications in their relationship.
However, the situation will be different when Kate ascends to the position of wife of the Heir to the Throne, but it is not yet known if she will take the title.
Kate can follow suit and not take the title, or she could use it as a tribute to the stepmom she never met.
After Prince Philip’s death last month, Prince Charles received his title of Duke of Edinburgh, but he will not use it.
When Charles becomes King, the title will go to the Queen and Philip’s youngest son, Prince Edward.
