Prince Charles is in a “very uncomfortable” and "frustrating" position of waiting to be king and feeling he has been ready to take on the position for around 20 years, said a relationship expert.

Having been born into roles gives sibling rivalries an extra level in the Royal Family with Charles having lived virtually all his life as the king apparent.

But with the Queen still going strong at 95 it means that Charles is having to bide his time and is set to inherit the throne into his old age.

Neil Wilkie, a relationship expert, believes that the way the royals get on with each other and their personalities in general are influenced strongly by their royal destiny.

Mr Wilkie told The Express: “Prince Charles has been in the very uncomfortable position for many years as the king-in-waiting, waiting for his mother to die.

And she’s outlasted many expectations, so he’s in a very frustrating position that he probably felt he was ready for the role about 20 years ago and it never happened.

“It may not happen for quite a few years to come and if he does become king then he’s not going to have a very long shot before he passes on and it goes to William.”

With Charles’ life being based around this expectation to be king, Princess Anne has had none of this pressure and has been able to get on with her life as a hard-working royal without causing drama.

Mr Wilkie feels that Anne has been able to accept her role whereas Prince Andrew has had more difficulty.

He continued: “If you look at Princess Anne, she has taken on the fact that she can never be queen anyway, but she is a royal and a hard-working diligent royal who generally rows the line and is a nice person to the rest of the world and works hard and is a great representative for the Royal Family.

“If you look at the other relatives, Prince Andrew hasn’t exactly been a shining example.

“So fundamentally a dysfunctional family and the normal ones are fairly rare and Princess Anne I guess I would classify as fairly normal.

“The rest are really weighed down by tradition, expectations, media interest.”

It is an argument that could also be used for the sibling rivalry between William and Harry with the Duke of Cambridge born with the likelihood that he will become king one day whereas for his brother his position is less defined.
