At 93-years-old, Queen Elizabeth is a much-loved monarch, and has always said she will never abdicate, however a Regency Act could be invoked if she is no longer able to perform her duty as Queen.
According to the Act, if she was incapacitated, or evidence provided could prove "that the Sovereign is for some definite cause not available for the performance of those functions" then Prince Charles could rule as Prince Regent until her death, when he would ascend the throne.
If this were to occur, Prince Charles would take on the Queen's duties, and Prince Philip would become a guardian of the Queen.
Prince Charles is already taking on more royal duties, some of which would have previously been looked after by the Queen.
"He is starting to do that already, being at the state opening in Parliament and the Commonwealth conference," Phil Dampier continued.
"He is starting to take over a lot of the duties and doing the investitures."
Alongside taking on more royal responsibilities, Prince Charles is also proving a vital ally to his daughter-in-law, Meghan Markle as she grapples with her own family dramas.
Meghan has turned to Charles recently with her own father being absent from her life.
