The cypher of King Charles III has been revealed, showing an image to be used by government departments and on state documents and post boxes.
It was personally chosen by the King, from a range of designs produced by the College of Arms.
The monogram combines his initial "C" and "R" for Rex, the Latin for king, plus III for the third King Charles.

The cypher, a visual identity for the new reign, replaces the E II R of Queen Elizabeth II.
There will be other changes ahead to mark the new reign of King Charles:
- The Bank of England says new bank notes featuring a portrait of King Charles III are "expected to enter circulation by mid-2024", with the image to be revealed before the end of this year
- New coins will be produced, says the Royal Mint, and will appear "in line with demand from banks and post offices". There is no date set for when they will be in use, but an image of the new King Charles coins will be shown before they come into circulation
- There is a tradition, says the Royal Mint Museum, for the profile of a new monarch on coins to face in the opposite direction to their predecessor
- Existing banknotes and coins will continue to be valid, with Charles and Elizabeth notes and coins being used alongside each other. The Royal Mint says there are approximately 27 billion coins from Queen Elizabeth II's reign in circulation
- The Royal Mail says that new stamps featuring King Charles will "enter circulation once current stocks of stamps are exhausted"
But a set of four memorial stamps are to be released in November, showing portraits of Queen Elizabeth II taken at different stages during her reign.
As the period of royal mourning ends, the new cypher of King Charles will be used for the first time.
This personal monogram of the new monarch will have its first application in the Buckingham Palace post room on Tuesday, when it will be used to frank letters from the Royal Households.
It's an image that will begin to be used more widely, from uniforms to official stationery to public buildings.
