However, it turns out this is not the case, and while Prince Charles is to inherit the British throne, this may not be the case with the Commonwealth.
While the British throne is passed down as a hereditary position, the Commonwealth head position is not inherited in the same way.
Talks of a ‘secret succession plan’ have begun today to discuss who should be head of the Commonwealth, according to a source at the BBC.
What is the Commonwealth?
The Commonwealth is made up of 53 nations which are former territories of the British Empire.
Queen Elizabeth II was made Head of the Commonwealth at her coronation in 1953.
Which countries is the Queen head of state for?
The Queen is the Head of State for 16 of these nations, including Canada, Australia and Barbados.
A meeting is expected to take place today to look into how the Commonwealth is run.
According to the BBC, the meeting agenda reads: “Discussions will take into consideration the issues raised in the first session and also the wider governance considerations of the Commonwealth.”
A senior source at the BBC said: “I imagine the question of the succession, however distasteful it may naturally be, will come up.”
However, it is believed Charles is still the most likely candidate for the Commonwealth head role.
It is expected the group of Commonwealth officials will report the results of their meeting in April.
Queen is the longest serving monarch in British history.
She was crowned at the age of 25, on 6 February 1952.
However, many do not realise she was never expected to become Queen at all.
It happened under unusual circumstances, involving the abdication of her uncle king Edward VIII. But do you know what happened?
