In 1964 the functions of the Admiralty were transferred to a new Admiralty Board, which is a committee of the tri-service Defence Council of the United Kingdom and part of the Ministry of Defence. The new Admiralty Board meets only twice a year, and the day-to-day running of the Royal Navy is controlled by a Navy Board (not to be confused with the historical Navy Board described later in this article). It is now uncommon for the various authorities now in charge of the Royal Navy to be referred to simply as "The Admiralty".
