In order to be an effective King, Prince Charles, who is next in line to the throne, it is crucial for him to get the support of his two sons, Prince William and Prince Harry.

According to royal expert, Rhiannon Mills, Prince Charles and his sons would need to present a united front in order to secure public confidence that Charles can succeed his mother, Queen Elizabeth II effectively.

"In some ways, Prince Charles is just like any parent as they get older, they need the support of their children," Mills said in a report by Express UK.

Apart from getting support from his sons, Prince Charles would also have to take a page from his mother's book. Mills said that the reason that the Queen has been an effective and well-beloved royal in the past six decades or so, has been because of her ability to be discreet about her true opinions and become apolitical.

This, according to Mills, is something that Prince Charles has yet to master. The royal expert said that it has been quite difficult for the heir to the throne to understand his actual role in the past decades.

Mills said this has made the public quite curious to see what type of king Prince Charles will be when he ascends to the throne.

While there has been no confirmation, it has been speculated that Queen Elizabeth, who turned 93 this year, will be slowing down on her activities and will be passing on the torch to her son by this year on her 94th birthday. It is likely for the Queen to follow in the footsteps of her husband and consort, Prince Philip, who retired to the royals' Norfolk home as he stepped down from official functions in 2017.

An indication of this is the Queen's inclusion of the Prince in her meetings about matters of state. According to a Town and Country report, the Prince has also been added to the distribution list for the Queen's official despatch boxes. This marks increased responsibilities for the Heir Apparent.

Prince Charles will also likely open the 2020 Commonwealth Heads of Government meeting in Rwanda after he was appointed as his mother's successor as Head of the Commonwealth. 

This is something that that royal author Phil Dampier is also expecting, but he says that the Queen could do this on her 95th birthday. She could invoke the 1937 Regency Act to relinquish her royal duties and pass them on to her heir. 

"There is talk that when she reaches 95 in a couple of years she may slow down and possibly the Regency Act will be brought in. She will still be Queen but Prince Charles will, in fact, take over most of the duties. He is starting to do that already, being at the state opening in Parliament and the Commonwealth conference. He is starting to take over a lot of the duties and doing the investitures," Dampier said in an interview
