King Charles III has used a new signature for the first time after being formally proclaimed as monarch at the Accession Council. During the first part of the meeting, His Majesty's role as King and regal name were confirmed in front of many important attendees, including Queen Consort Camilla and heir to the throne Prince William.
The event was televised for the first time ever, with Queen Elizabeth II's happening behind closed doors 70 years ago, which gave us incredible insight into the formal process, the Mirror reports. The new King followed a tradition going back centuries by signing the declaration with 'Charles R' - but he added the letter for a different reason to his late mother.
The Queen used the signature 'Elizabeth R' on official documents - but it's not to represent a secret name. It actually stands for 'regina', which means 'queen' in Latin - and because Charles is King, his 'R' stands for 'rex'.
