Upon a "demise in the Crown" (the death of a Sovereign) his or her heir immediately and automatically succeeds, without any need for confirmation or further ceremony. (Hence arises the phrase "The King is dead. Long live the King!") Nevertheless, it is customary for the accession of the Sovereign to be publicly proclaimed. After an appropriate period of mourning has passed, the Sovereign is also crowned in Westminster Abbey, normally by the Archbishop of Canterbury. A coronation is not necessary for a Sovereign to rule; for example, Edward VIII was never crowned, yet was undoubtedly King during his short reign.
