There'll be some changes when King Charles takes to the throne.
It's something the Queen herself has addressed, in a letter she shared to mark the 70th anniversary of her accession. In it Her Majesty wrote: "And when, in the fullness of the time, my son Charles becomes King, I know you will give him and his wife Camilla the same support you have given me."
Without a crystal ball, it's impossible to see exactly what the future will look like for the royals, but there are some things that can be expected to change when Prince Charles becomes king.
Postboxes, banknotes and the national anthem are among the things that will change under the reign of King Charles, according to The Express. Here's how:
You might have noticed when you've popped a letter in a postbox that there's an engraving on them of EIIR - that's the Queen's cypher. It stands for Elizabeth II Regina, with the latter meaning queen in Latin.
However, when Charles becomes King, any new postboxes put into place would bear his cypher. If Charles decides to go down the same route with his regnal name (he can choose to keep Charles or a different name when he becomes king), then his cypher would be CIIIR. That's King Charles III Rex, with the latter meaning king in Latin.
Interestingly, you won't find post boxes with EIIR on them in Scotland. Instead mail boxes there have the Scottish Crown on them.
According to this handy explainer from the Postal Museum, it's because some Scots "do not accept the current Queen Elizabeth as the second monarch of her name, since Queen Elizabeth I was never ruler of Scotland."
Of course, you can expect stamps to change too. A miniature silhouette of the monarch's head is depicted on all stamps, so we can expect stamps to have an image of Charles on them instead once he becomes king.
When Prince Charles becomes the reigning monarch, portraits of him will be printed onto banknotes by the Bank of England and will also appear on coins produced by the Royal Mint.
Although they will enter circulation when he ascends the throne, The Express state that it will take several years before all the nation's currency will be replaced.
You don't need to know all the words to the national anthem to recall that 'God save our noble Queen' plays a vital part in it. Obviously, this will need changing once Charles is king and it's expected that the first time we'll hear this version will be at his and Camilla's coronation.
Lyrics such as 'send her victorious' will also change to reflect the new monarch.
